Hi all,
I have been having issues for several weeks now with a 22 Dodge Ram 1500 Etorque with first initial startup.
the back story goes as follows.
we have deleted the Generator and 48V battery for a TVS3000 S/C.
All before the Ecm was unlocked vehicle would start fine with no alternator or generator on first crank.
After the PCM was unlocked it was fine for about 2 starts then started playing up as follows.
I have emailed our support in Aus and in the USA with no resolution yet.
i have attached my correspondence with both support teams to make a better understanding for you all.
I am having issues with a 2022 dodge ram 1500 on First Start up.
If you put foot in the brake and crank straight away it will crank the Fire but cut out, it will continue to do this this for another 3 time's until it will not fire at all.
But if you turn the ignition to "run" and wait approx 5 seconds it will start fine, although will crank longer than usual.
The pcm has been unlocked and tested through Bench flashing and OBD2 with no issues.
The logs you see attached show this condition, I see and realise that the ltft and stft are nearly maxed out, but it was still doing this before this other condition.
Could this be a faulty pcm?
I have sent it back to vcm where it was unlocked and they bench read it and wrote and said that it was fine.
I have tried starting without the bypass cable which made no difference.
I now have lost coms with pcm in permanent set which May not be included in the attachments.
Any help would be greatly appreciated.
Good morning, I have looked over the multiple logs I have of this vehicle and as soon as it fires it cutting injector pw to zero, this seems like it is the immobilizer being active. Any continuing crank after this event shows no injector activity.
Does this sound like I am on the right path possibly?
Any guidance would be greatly appreciated.
