I've checked all 5 connectors on the ECU, and they are securely attached. If by rodent, you mean was a wire was chewed, that could easily be the case. My question is how to figure that out.
I'm trying to understand The diagnostic manual. I'm on DI-647 (an image is attached) where I'm checking the IG1 relay. The open/continuity is ok on my IG1's pins, so next it says, "Check for open circuit in harness and connector between IG1 No. 1 relay and combination meter (See page IN-36 )."
Can someone tell me how to check for that open circuit?
Sorry to liven up an old thread but can anyone tell me the location of IG1 No1 in the engine bay. I assume its under the main fuse block but it looks difficult to take apart. I have a ABS light on all the time but no fault codes on Scan gauge or when put in diagnostic mode. Help Please.
