Now that we have diagnosed the Dodge Caravan with the code P2308 "Ignition Coil 3 Secondary Circuit - Insufficient Ionization" in the first video, it is time to replace the ECM with a used one and see if we can figure out the rest of this puzzle.

Autel for the win indeed.
This anomaly happened on cylinder 1 in first video
Straight science! Study, replicate! Study, replicate! Discover diagnosis!! Love it!!
Epic videos. I replaced my plugs cables, ignition coil, and still I have a misfire
misfire data is under system check in Autel
My 2017 Dodge Grandioso flagged an engine light this morning. Now at the shop running a diagnostic and I am hoping I can interrupt the shop manager and say, "wait, let me guess … a P#### cylinder misfire code?"", well my friend this is how we fix it … and then link to your video!
ooops lol
“Ah sh*t it’s got to be warmed up” bahahhaha
How long and how much should something like this be. Here in year 2021 and in Evansville Indiana.
In autel, check MODE 6 for misfire counts. There is a kind of COP probe BAR for picking the coil secondary spark signals on sequence. two bars serial connected for two banks of coils, the fire order is 1 2 3 4 5 6.
Looking for some ideas . 05 Chrysler Town and country with the 3.3. Idles nice, but won't develop any power. Starts running rough around 3500rpms, won't upshift till you let off the accelerator. If you want to go into passing gear, it's like you shifted into neutral. Exhaust glows right after manifold on 2,4,6 bank. Compression is good, codes P0404, P0406, & P0700
E=mc2
Latest update on autel it now has misfire data
Your diagnoses is good enough to justify throwing all new coils at it.
Oil change light out of fuel miss fire ecm in the toilet
Hi how are you
Thanks for this video I learned a lot of from you
But when you replace used ecu you don't need subscribe with launch x431 or ezydiag only write vin number the car should be start
Thanks
Diagnostics will not drive the Amps that high..You would asking for trouble. As the fuse is only rated for what 20amps?
How, do you keep going?? Investigating
New drinking game: Take a shot every time Eric says "Opps" while stabbing at the scan tool! ;>)
Such an interesting case study… I'm hooked! Part 3, here I go! 😁😅
Eric, I can't help but think that the reason tech authority wouldn't allow you to enter that PIN was because you didn't rewrite the VIN into the donor PCM first. I'd bet that would have saved you the trouble of swapping the boxes around as much as you did.
Big compliments, you take lots of time to diagnoses the problem 👍. Instead of hook on a computer to read the codes and throwing part on the car to replace. What most shops do.
Love to watch your videos 👍👍👍
Swap that coil see if problem follows the coil
A head scratcher. Thanks for the video.
I am curious.I would like the condition of the spark plug and compare with the rest.Also the coil
I know it’s an old video but if you ever run into that issue again, look at the top right it tells you the vin it’s reading and at the time you were having the issues it was reading the vin out of the used pcm not the car.
Switch the coils see if it moves
do you get the key code with the subscription?? also autel does programmable module installation for fords its a bad ass tool
and I believe it was an newer.. town and country
I seen that same coil pattern on a danner video ecm was fine he switched coils.. and same thing bad coil
I have an autel at my shop. I was trying to program a set of keys but couldn't get the 4 digit code from the dealership. Is there another way to obtain it? How did you get the security code?
Mopar Giant shows about $40 for coil,plug and capacitor. You have many hours/dollars in diag ,why ?
"crap biscuits" they ruin my process as well. lol
that's interesting
hi eric just a thought but there is a website you can go to called IATN international automotive technicians network you can usally find any good known waveforms for coils crank and cam sensors any waveform you need and I believe it has nkown bad ones also
How much do you charge for diagnosing an issue like this. I run into the issues occasionally that take 3/4 hours of work, but at my rate that would be 400 dollars…
Hi eric, i like your rhythm , momentum and genuine excitement as your diagnosis unfolds. love watching your videos, keep them up.
I have been watching your videos for a while now and I appreciate you keeping your channel clean.
Since the current limit in the PCM is set to about 15 Amps and the anomaly goes to 17 it almost has to be something in the coil. If there is a hole in the coil with carbon tracks around it we can do wild speculation.
Here's some… if there is a fault between the primary and secondary on the auto transformer where the secondary arcs back over to the primary sending HV back to the PCM it will not be a happy camper.
Can't it be the TIPM? It is a Chrysler! LOL.
That was excellent trouble shooting Eric. I personally think that the computer senses something wrong with the #4 cyl. and firing it again. I would swap the coil to another hole.
This same problem was on #3 before the ecm was swapped. So, is there a sensor that is sensing that 1 coil (was 3 , now 4) has not fired and is trying to correct it ?????
Wow, what a pain in the bum programming that thing! I'd have been melting down big time thinking I just made a brick, lol.
I'm going to have to check and see if the Autel I got has that capability. I don't have the Elite.
Can't wait for part III ! The suspense is killing me!
Eric O did you try to put it in Drive to duplicate the original bad misfire at all? I am just curious if your bad wave form on the #4 would be more drastic or consistently bad with a load on it?
Did you check the blinker fluid?
I can't jump to conclusions but one of the You-Tube certified techs should know the answer. Send em a badge, Eric. HaHaHa
Watching again, not the how long the coil is "ON" for when it acts up compared to how long it, or any other coil, is ON for ! When it messes up, it is starting to charge (dwell) the coil coil much longer. Why it starts charging early is an unknown.
It would be interesting to look at the crankshaft position sensor pulse in relation to those 2 waveforms. One thing that will cause early charge time is "adaptive dwell", which is where the PCM thinks the engine is accelerating so in order to get a full charge on the coil it starts charging the coil earlier.
