Pinpoint Test N: The Cornering Lamp Is Always On

Refer to Wiring Diagram Set 91, Cornering Lamps for schematic and connector information. Diagrams By Number

Normal Operation

The cornering lamps are provided voltage when the parking lamps are on through circuit 14 (BN). The ground path is controlled by the multifunction switch through circuit 380 (VT/YE) for the LH cornering lamp and circuit 379 (BN/WH) for the RH cornering lamp. When the multifunction switch is placed in the LH or RH TURN position, the multifunction switch completes the ground path through circuit 57 (BK).

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors
- Multifunction switch

- Ignition OFF.
- Disconnect: Multifunction Switch C202c.
- Place the headlamp switch in the PARKING LAMPS ON position.
- Does the cornering lamp continue to illuminate?

Yes
REPAIR the circuit in question. TEST the system for normal operation.
