I’ve come to the conclusion the J519 has gone bad, at least at the ‘A’ block connector (did not test connection for rear lights but suspect the same result). I tested the leads in block ‘A’ (front lighting) on the J519 (Vehicle Electronic System Control Module) and found very low voltage for the headlight. I did a continuity test on all relevant wires and they are fine. I have searched the forum and could not find specific answers to my questions, so before I spend a lot of money on both parts and tools, I’d like to ask this community the following. As a result, I have learned a lot (thanks), I have purchased the repair manual from Bentley’s Publishing, and I’m looking at buying the diagnostic cable/software from Ross-Tech. I have read many threads on this forum looking for advice for my problem. The problem used to be intermittent, but now, right side is not working permanently. All lights on right side are out (headlight, tail light, turn signals (front and back), brake light). Hi, I’m new to the forum, hoping to get some advice.
