As a follow up to my introductory post:
3 OBD scanners fail to communicate with my ECU.. Autel, Innova and the cheap red HF scanner. Connector pinout yields the following (using pin 5 as grnd) Key on Eng off.
Pin 1 10.6v
Pin 2 empty
Pin3 .o5V
Pin 4 grnd
Pin 5 grnd
Pin 6 empty
Pin 7 11.3v
Pin 8 12V
Pin 9 10.4v
Pin 10 empty
Pin 11 0v
Pin 12 empty
Pin 13 11.2v
Pin 14 empty
Pin 15 7.6v
Pin 16 12v
This was a fleet vehicle that had a GPS box installed, I removed it. Everything else is in tack.
Also the turn left turn signal is operational to at least the relay (it clicks fast but no lights, dash or otherwise) bulbs and fuses good.
Would a failure in the fuse box disable communication to the ecu and also muck up the left turn?
Am I looking at a trip to the dealer for possible ECU repair?
How are these guys?
