RUNNING LIGHT CONTROL MODULE INSPECTION


id091800807900

1. Connect the connector to the running light control module.

2. Connect the negative battery cable.

3. Measure the voltage at the running light control module using voltmeter.

• When inspecting terminal 1G, 2J or 1J for continuity, disconnect the running light control module connector.

4. If the value are not as specified in the Terminal Voltage List (Reference), inspect the parts under "Action" and related wiring harnesses.

5. If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the running light control module.
