1. Turn Signal Lamps Malfunction

2. Turn Signal Switch Malfunction

3. Turn Signal/Hazard Flasher Module Malfunction

Circuit/System Description

The IGN E fuse in the engine wiring harness junction block supplies Ignition positive voltage to the turn signal switch assembly. With the ignition switch in the RUN or START position, ignition positive voltage is connected through the turn signal switch assembly to the turn signal/hazard flasher module which is powered by the HAZARD fuse also in the engine wiring harness junction block and is grounded at G201. When the turn signal switch is placed in either the left or right position, the circuit is complete from the turn signal/hazard flasher module to the turn signal lamps and to ground. The turn signal/hazard flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators. The front turn signals are grounded at G103 and G107. The rear turn signals are grounded at G401 and G402.
