I bring you along in this video not just to show you a fix on a Nissan Versa with a P0705 but I show you the value of having a library of service data. In this case it was Identifix that gave me a silver bullet on a repair that likely would have taken some time to figure out.

Excellent video, however, I'm still not sure why a loose connector pin on a rear panel light assembly would cause the computer to not properly determine what drive mode was being selected.
it's not just the backfeeding power being picked up by the driver as the reverse signal, it depends if the reverse signal is actually being used by the transmission control module as the actual condition not the requested condition, so you get a conflict with more than one signal in which sets the code
The things that are hidden in software / firmware. That make no sense and no one knows about. Great work. I have chased so many loose connections over my years. Some are fairly easy and most are real bears in the woods.
Me: How'd you fix the transmission?
Mr. O: Repaired the taillight connector.
Me: Hmmm…what?
Very interesting. I like your method and follow up.
Very nice video!! Thank you for sharing the knowledge!! God Bless!!!
Always appreciate your in-depth review. Going off the beaten track like so many others do. And not doing what many shops do and fire the parts cannon at it.
Gearbeitet ONCE
Import Mr. O. Lobed IT 👍your THE man!
The Nissan keeps wanting the D.
Awesome video, just goes to show you that electricity does take the path of least resistance. It is wild the way a bad ground can mess with the flow of power to other components of a circuit.
Let the countdown to a well-deserved 700,000 subs begin 👍🏽🔧🧰👊🏽
That reminds me of a car I owned a while ago, it was an ED falcon but this problem covered the entire range from the EB2 to the ED falcon to LTD fitted with the Smartlock imobilation system, if the high mounted brake light globe blew (burnt out) it would activate the Smartlock system and you couldn't start the car.
Whoa whoa whoa! My guy, you forgot one little thing! "WHATS IT GOT STUNTMAN!"
What was the ? 😂
What size t-pin do you use, i only seam to find large ones? Love you videos. Thanks
Thanks for coming in today Fella 👌👍🍻
You do good work 👏
Water in the tail lights? I see this all the time . it's a backfeed through the tail lights. You can also get a transmission drivability problem because of water and the tail lights.
Bolts were loose someone replaced a bulb and didn’t connect it properly
I heard you say kanueter valve and I cracked up.. I used that part name in the early 80s while working in the walmart service center. Our promotions gal came in with her new chevy nova ( the import one ) for a oil change. She was cute and I thought I'd give her a hard time. I told her that her kanueter valve failed and the main bolt keeping the engine together rusted out. She freaked out because she just bought the car. I let her rant for a bit and told her I was messing with her and the car was fine. I thought she was going to hit me. She finally laughed. Anyway nice find using your diagnostic skills.
As a professional tech, identifix is useful some times like you say grain of salt but also sometimes the motor specs have more published info the all data (somedata) can’t speak for pro demand as we don’t use that where I work
Great job Eric, and I hope your Father's Day was amazing!!
Does SMA contribute any of his wisdom to these digital knowledge databases?
Love watching your videos, a true automotive technician. You use your noodle, you're honest. I wish I was years younger and you needed help in the garage. I was a Chrysler,Dodge, Jeep tech for over 30 years. I saw a lot over the years and I can tell you are one of the best auto technicians. Thank you for your videos.
Now THAT was a strange one! I never would've guessed that in half a billion light years! Some great info there! I'm in that stuck-in-the-middle stage of my career. I don't get enough diagnostic work, or even automotive work in general to justify the expense. Now, some months I do – sometimes I'll get several per week … but at any moment it can go away for 2 months straight where I'm just doing tires and brake jobs, or just doing lawn equipment, chainsaws, and ultralight aircraft (How's that for a mix?), and won't need to look anything up. Wish they had an in-between service that's above DIY, but below full shop cost. Or a pay-per-view service like AllData. That's where I'm at! In diagnostic limbo, so to speak, lol. Great stuff as always, man!
Hope you can rely to this. What do you use to clean off green snot from a bundle of wires. This could be product promotion for you. Thanks, Steve
Not the first time a come across whacky shit like that in that tool.
I felt the same. Like wtf? Do taillights have to do with a transmission. And sure enough.
I'm onto different things now I have decided recently.
I'll always work on own and help a few friends when I have time.
But im at 50 moving onto my true calling. Food in the summer spring and fall and And rehab construction in the Winters. Into spring starting end of fall.
More Rewarding to me and more money less overhead.
I love these videos and all the channels like yours that will keep me up to date on this engineering disasters caused by engineers being dicks due to their wives cheating on them with a mechanic Hahaha
who cares bout the cat mat i want the star wars bag!
Your adage, "the money light.." never been so true!
Tail lights on a dodge truck have similar quirks. Sometimes it seems as if the routing layout was an after thought. Got very familiar with the schematics over the years out of necessity.
i used to have some trouble to untill i purchased for a fairy price workshop manual from somewhere workshopcarmanuals i dont know what,but it helped,more easy with many pages
In Nissan connector numbers B=body harness. M=main harness. E=engine harness. F=fuel injectors
Good job there Eric definitely a uh a good fix and a good dad helper there. Dumb backfeed issues are really a nightmare at times and it pays to what things over on the old side to see if there is any issues other than the codes I've found at sometimes a non functioning piece or weird functioning piece will lead you to the fix so good job keep up the good work and pay this is all more money she is a good asset
Great video and wow I learnt a lot. Here in the winter salt belt . We lose ground s all the time. The road salt eats them off the frame or body
Funnily enough, had the same problem on a 1977 Morris Marina. What's that you ask? Doubt if they were popular in the US, but in 1979 I saw one in……Altoona Pa. ! Moral of story, don't overlook the bleedin' obvious. To that I would add, start with the simple stuff…. Thoroughly enjoy your content. Regards from UK
Same thing with old 90s-2000 VW… set the MIL when both breaklight bulbs are blown.
Breakpedal switch malfunction.
In my experience they tend to work loose again
"just crank the engine over, watch me scream" hahahaha. I'm laughing way to hard at that. My other half has actually done that to me.
Plus, I held a spark plug on a generator and got a mate to crank it to check it was sparking as we couldn't see it.
Hell, it's not stupid if it works…
hi Eric between you and ray you pair have got me out of some sticky situations with repairs i had some thing similar a few days ago with my trailer lights what it turned out to be was a loose wire in the plug that had frayed and was touching other connectors 30 min later all fixed without a service call saved me some big $$$
That was a weird scenario and i would never have dreamed to look in the tail light harness. I am sure you would have found the issue with the identi fix but the time you saved by checking out what a prior fella had posted as his fix..thats priceless. And the drag test…you think of all the connections in a wiring harness and everything is just so but if there is one teensy bit not the same it causes problems. It really is in the details…sometimes finite details at that not to mention the 2 loose t/light nuts as well.. A great video Eric!!!
In 1973, I owned a Datsun 240Z it had a drivability problem I could never find, until the small ground wire between the back of the engine block and the body of the car became loose. When I noticed the wire became quite hot I tighten the bolts and the problem went away. On the 1973 Datsun 240Z the battery ground cable was grounded to the body of the car not to the engine.
I so hate shops that SCREW people out of money… A BIG Thanks to guys that show videos like this and TAKE THE TIME to UPDATE sources like Identifx with stuff they were even too lazy to identify. Thanks, Great Video and a BIG THANKS to @Rainman Ray's Repairs for pointing me over to see ANOTHER Honest Mechanic who likes solving puzzles! "THE GOOD GUYS!"
there is corrosion that builds up on the board in the tail lights. I changed the range sensor/neutral safety switch first and to no avail, after I cleaned the corrosion off, didnt work. I replaced the whole taillight. BOOM FIXED. This is my aunts 2013 versa. There is a service bulletin on this fix. Insane how this is all wired.
Why did you choose Autel scan tool over the other options. Thank you
Eric, did you add your fix to the Idenifix site?
I'll be dipped nice nod to VGG eric love that guy too.
Wow. That video wasn't what I was expecting. Bad grounds cause alot of problems it seems.
Just saw it a second time …Good job !
Do not use identifix. Do not know any shops that use it either. That said the issue you had on that Nissan was quite unique. I could see how it could have led you down the rabbit hole. This addendum in Identifix surely led you down the path of a successful repair.
Rainman Ray sent me…👍
Great video sir
Love the channel and Rainman auto said hey
Couldn't anyone just google the problem, instead of paying for a program?
the beauty of this was all you needed to do was look at the back lights to see they were messed up. you always want to do the easy diag first, then go deeper. nothing worse than doing 5 hours work just to find it could have been fixed in 5 minutes.
Greatt video Eric, toyotas has a similar issue too.
nissan versa 2010 and up have let to find the link to trannyshifting problem service info do not say anything bout trans to tail lights what the heck. fix your tail lights will fix your trans problem i see this 4 years ago
fyi my nissan dealer are good people they said check your tails water gets in the lights tranny goes crazy . thanks my guy.
i use mitchel ownedby snap on
Kinda like the Chevy HHR the cruise control won't work if the bulbs in the center break light are out
will i get burnt by buyin the new mx808 autel my solus is outdated
Good job explaining. I be worried about breaking the connector.
Ok but the previous dude who figured out the tail light was the problem
A Guy Before You Jabbing With a Test Light.
LMAO… You auto guys have it so easy. Plug in a scan tool and all the answers are there in front of you. Nothing like that in my industry where I need eight bits of expensive test equipment to make one basic operating change, but that's radio broadcasting for you…
But I'm still perplexed as to why a ground on a tail lamp fitting would affect the transmission position sensor…. Totally weird.!! … and I'm glad I don't own a Nissan.
Been watching for a few years now and this has to be one of the most entertaining and educational videos that you have published. Well done Mr. and Mrs. O.
WHEN YOU NEED TO TAKE AN “AMBER HEARD”. (T-PAPER IN THE TRUNK).
eric a quick heads up if you get silly strange or odd codes /eventss on a fiat or a lancia then look under the headlights from behind the main fumction earths are located there
Once again your videos are very informative and interesting. Thanks for being a great teacher!
the biggest problem is that nissan got into bed with peugot citroen some yearars ago and the citroens would throw all sorts of faults up between the headlights the wipers and the alternator / charge rate
But now do you get to note what you did in the service data cloud for the next guy?
For a Drag Queen Mrs O is pretty convincing🤣
Great video Mr O 👍
Great job as always Eric. Reminds me of when I changed my brake lights on my 2012 Accord coupe to LED and the cruise control would not work with the head lights on. I found a fix for it. Took a couple weeks for me to understand what was going on. Keep them videos coming.
Nissan quality stinks, as Scotty Kilmer always observe
Nice vid Eric, Rainman Ray sent me over… I have watched some content on your channel before and always knew you were a "stand up" guy. Great job on the easy fix.
Thank you, my uncle Carl told me one time he spent 3 days on a 82 or 72 jeep like vehicle with a misfire. As he was at his wit's end and was going to give the customer it back. He noticed a taillight out and thought he should at least fix it. After that he started it up to back out of the shop and yup No misfire! He had to know so he put the old light back in and yup misfire. Thank you for your videos and remembering my uncle Carl. Him and his brother Eric were both master mechanics. They taught me most of what I know. Now I watch great people like you.
Incredible:
1. That diagnosis is pure karma
2. It points to industry-wide engineering failure. That a loose tail-light connector could put an otherwise healthy vehicle out of service and make it undriveable is Bad Engineering. Its bad systems design. And to follow-up with no way to track the problem thru networked electronics (totally unnecessary for tail lights) is shameful. Entire service industry should call-out those ivory-tower engineers who are making money by early obsolescence. Rather die by rust than by corroded wiring harness.
Sorry for rant. It was a great diagnostic video. Watched 4 times. Trying to figure out how to acquire some of that diagnostic Karma. Thanks Eric!!!!!

Nissan created a huge headache by saving less than a nickel on that part.
followed a link over here from rainman rays repair channel, although ive been a southmain subscriber for years heh heh heh. commenting to not be a jerk!
Alldata Tech Assist-They hold your hand through the entire repair and you can call as many times as you need with no extra charge.
One video in, recommended by Rainman Ray, and you have another subscriber. I'm an Aussie though so if I ask questions don't hate me
Rainman Ray told me to come over to this channel to check out this episode.
Even older cars have a ground problems with rear lights. Most people don't know how to diagnose that either.
I'd suspect that the control module doesn't buffer the reverse switch lead, it just measures the voltage from the lamp. Since the lamps had no ground path, any time you hit the brake light or others, you drove the line to the reverse switch high, through the reverse lamp, with the bad ground.
I don't much care for rear light that are sealed units. These often have a PC board can can have connection issues or broken solders.
Another example of previous peoples problems saved me a minimum of $150. My dash would drop all the meters and light the airbag and seat belt lights only. If I slapped the dash things would come back on. It effected the back lights for the instruments as well as no turn signals. The headlights worked fine. My car is a ford Freestyle. There is a group on the web that post its problems and fixes. I found one that was a match. It said the uController, on the right side of the instrument panel's, crystal had a solder problem( Euro Solder, no lead! ). It would fracture and have bad contact. I took it apart, re-soldered it and not problem since. There were a several after market places that would service the cluster for $150. I suspect all they do for many of these is re-solder the crystal. I suspect it is like the three taps of the hammer, joke, it is just knowing where to tap it.
Another time my wife's Toyota's clock was flaky. The display would go out. Toyota wants $275 for the clock. I see people on the web offering $50 to fix it. Something that cheap means it has to be something simple. I open the clock and press on things a little. When I pressed on the large surface mount resistors, it would light up. Another case for Euro Solder. ( 10 years later it works fine after I re-soldered them )
Another great video sir with great tips to avoid the shock and awe of the parts cannon! Three things…. one – it was nice to see the cross collaboration with Ray two – the innuendo gave me more than one good chuckle three – that guy that published the great tip needs a patreon account =)
rainman ray's repairs send me over here great video I subscribed 😀
You know you trust your wife when you are standing behind a vehicle and tell her to put it in reverse.
GD NISSAN TAIL LIGHTS! I had a inop cruise control because both tail lights were burnt out. I missed that for days and my coworker found it in 10 minutes
I think Identifix gets a bad rep bc everyone points out the silver bullet allure BUT no one mentions the testing they layout for you as well when you looking something up. Its a lazy tech problem, not an Identifix problem
Rainman Ray's Repairs sent me over. Thanks for the video.
Hey Eric, I hope that the "parts" magazine is NY compliant! 10 parts or less for you buddy, otherwise, your pinko commie government will be paying you a visit. Good explanation of how valuable Identifix can be, it can also be a bunch of rope to hang yourself with.
I am Swiss and I tell you that most of shops overhere make that opposit of you: they see diagnostic Codes and just exchange this parts what tells the Code! Instead when I ask for a issue, the answer is always the same: there are no diagnostic Codes storaged, your vehicle is in great condition!
I whish I could find over here a mechanic like you…😊
this is vantastic youtube chan, great work learned a lot here
Basically identifix is not a diagnosis, it a starting point.
Man what a silly design, that a light wire connection can cause such a problem.
