Specified value: battery voltage
If the specified value was obtained:
-
Check the wiring from the Battery to the Transmission Control Module (TCM) J217 electrical harness connector T52 terminal 3 for an open
circuit or a short circuit.
-
If necessary, repair the faulty wiring connection.
If the specified value was obtained:
Checking Ground (GND)
-
Using a Multimeter, check the Transmission Control Module (TCM) J217 electrical harness connector T52 terminals 1 and 2 to Ground (GND)
connection on left headlight for resistance.
Specified value: 1.5 Ohms.
If the specification was not obtained:
-
Check the Transmission Control Module (TCM) J217 electrical harness connector T52 terminals 1 and 2 to Ground (GND) connection on left
headlight for an open circuit or a short circuit.
-
If necessary, repair the faulty wiring connection.
