1, Check the "P- GND" Wiring Harness
1. Place the key switch in the OFF position, unplug the engine
ECU wiring harness connector 2 (machine side) from the
socket, and measure the resistance between each of engine
ECU terminals V39, V59, V79 or V80 and the chassis ground (at
the wiring harness side).
