Chrysler Repair/ASD problem


QUESTION: Hi Roland the measurement of resistance with multimeter set at 200 goes between 01.5-00.8 was taken with #5 fuse and #1 fuse removed also plug at PCM with the pin #46 with the green and orange wire we've been chasing, removed. ignition off and the other components I disconnected during troubleshoot.Thanks

ANSWER: Hi Steve,
The only item you didn't list was the ASD relay itself which I will assume is also removed from its socket. (If the ASD wasn't removed, then do that and re-measure) If that is now the case then there is Either:
A short circuit inside the powerbox itself (which I doubt), OR
A short circuit somewhere along the red/tan* wire that comes from a splice inside the powerbox and goes to the PCM plug pin #46 which you have unplugged at the moment.
So I suggest that you start at the PCM plug and trace carefully along the harness as far as you can in the hope of finding a place where that red/tan wire is shorted to another wire or to a piece of bare metal. The reading of 0.08 will certainly cause fuse #5 to blow as would any reading lower than 0.6 ohms and even 1.5 ohm would likely blow the fuse when you have all the other items plugged back in.
If that search doesn't produce a reading close to infinite (as there is nothing else connected to the #53 fuse pin) then there has to be a short in side the powerbox proper.
Thanks for verifying the reading.
And thanks for the rating/nomination which now has totaled to 5, so no further need since that is the maximum that Allexperts will "count" from a individual questioner.
*The wire I'm suspecting is actually red/tan not dark green/orange, so excuse my error.

QUESTION: the pin ive been measuring was not pin 46 my eyes are a little bad and I realize just now it was on the other plug.Is my time used up?

No, you are close to the answer. So keep at it. But please ask follow up questions rather than new questions, so that the history of the progress stays in play longer.
So actually the wrong plug was disconnected which means the red/tan wire at pin 46 was still connected which may explain why the resistance was so low. So re-measure resistance from pin 53 of the fuse to ground and see what it actually is.
