- Ignition ON, observe the scan tool Left Turn Signal Switch parameter while using the turn signal/multifunction switch to turn the left turn signal on and off. The parameter should cycle between Active and Inactive.
- If the parameter does not cycle between the specified values, refer to Turn Signal/Multifunction Switch Circuit Test. .
- If the parameter does cycle between the specified values and the left turn signal is inoperative, refer to Turn Signal Circuit Test. .
- Observe the scan tool Right Turn Signal Switch parameter while using the turn signal/multifunction switch to turn the right turn signal on and off. The parameter should cycle between Active and Inactive.
- If the parameter does not cycle between the specified values, refer to Turn Signal/Multifunction Switch Circuit Test. .
- If the parameter does cycle between the specified values and the right turn signal is inoperative, refer to the Turn Signal/Multifunction Switch Circuit Test. .
- Ignition ON, place the turn signal/multifunction switch in the left turn position. The left turn signal indicator on the IPC should cycle ON and OFF.
- If the indicator is always OFF, replace the IPC.
- Ignition ON, place the turn signal/multifunction switch in the right turn position. The right turn signal indicator on the IPC should cycle ON and OFF.
- If the indicator is always OFF, replace the IPC.
