TITLE: Turn Signal Diagnosis

APPLIES TO: Sephia

SERVICE TIP:

CONDITION

Left and right turn signals do not work, but hazard light operation is okay.

CORRECTIVE ACTION






Do not replace the combination switch until you have tested the hazard switch as described below:
- First check to make sure the turn signal fuse is good.
- Next check for power (12 volt) at connector C234 pin #8 of the hazard switch.
- If there is no power at pin #8 of the hazard switch when the hazard switch is in the off or non-energized position replace the hazard switch.
- If hazard switch and wire harness to combination switch is okay, replace combination switch.

Comments:
Power is supplied to the solid state flasher module from pin #8 of the hazard switch. In the off position, pin #8 is electrically connected to pin #5 of the hazard switch which is directly connected to the 10 amp turn signal fuse (see circuit diagram below). Therefore, if there is an open in the hazard switch, power will not get to the combination switch.
