Hey folks.
So this Jetta 2.0 is in a Vanagon. It has run ok for thousands of miles but has had a few consistent minor issues.
I went through the harness, again, using several different versions of wiring diagram. I found:
No ground to ECU 33. ("sensors ground") This has been corrected. Associated sensors were connected to ground however.
VOM on ECU 1 and 54, no power, ign. off. I may have wired it to the 15 buss. Ran out of daylight to check.
What exactly does the ground to ECU 33 do?
What difference will it make if I wire ECU 54 to B+ (constant power)?
Thanks. Neil.
