- Turn ignition off. Disconnect control unit harness. Turn ignition on. Check voltage between body ground and terminals "G" (Black wire), "J" (Black Wire) and "K" (Black/Yellow wire) of control unit harness.
- Voltage should be present only on terminal "K". If voltage is present on other terminals, check for short to voltage. If voltage is not present on terminal "K", check/replace "TURN" or "METER" fuse. If wiring is okay, replace control unit.
