Sick of this asd issue

so i ordered new ecu and i was able to start the jeep without the jumper installed, but it is idling like crap like its only on 3 cylinders.my odometer is flashing and my voltage gauge isnt reading anything but my led readout i installed is says the system has 18 volts. i called the computer company and they said they is still an issue with the asd system, like a bad ground that would make that circuitry over energize the system, is there a know spot to look for that would help me with my issue. just about to say screw it and just run the thing with the jumper, but i have a feeling i am not getting the performance it should have because i am piggie backing a system

Re: Sick of this asd issue

just saying.............

in your OTHER thread, there was MUCH HELP from frango. he is the forum WJ expert and was walking you through the correct troubleshooting. go back in there and follow his lead. throwing parts at it like a new ecu isnt going to solve something like a bad ground.

There was an actual issue with the ecm. But it has now unleashed a new gremil I didn't know about. The circuit now has power. And is turning everything on. That's why I started a new thread because it's a different issue now

Never mind. Just went over the posts from the other thread. I miss the part of him saying to make a new ground for post 86 on the asd relay and it fixed the issue. No jumper and she runs perfect. Sorry about the run around

Re: Sick of this asd issue

The voltage regulator for the alternator sits inside the PCM. So if with the previous PCM the voltage was ok, but now with the new PCM the voltage is too high, there is obviously something wrong with the new PCM. Just try and disconnect the small connector on the alternator. It will remove the power to the field and the alternator will stop generating power. Does the engine now run fine?

Just saw your answer now. Pin 86 is no ground, but is the power feed side of the ASD relay. The ground side, which is switched via the PCM, is on pin 85.
As mentioned in earlier reply, there was something wrong with the switching of the ASD relay. You did put a new relay in, which didnīt help. So then you will have to measure the wiring for continuity. You never replied anymore with any results thereafter.
