Turn Signal Indicator: Testing and Inspection
The diagnosis found here addresses an inoperative turn signal indicator lamp condition.
If the problem being diagnosed is related to inoperative turn signals or hazard warning lamps, be certain to repair the turn signal and hazard warning
system before attempting to diagnose or repair the turn signal indicators.
If no turn signal or hazard warning system problems are found, the following procedure will help locate a short or open in the left or right turn signal
indicator circuit.
Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of
wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
1. Disconnect and isolate the battery negative cable. Remove the instrument cluster.
2. Connect the battery negative cable. Activate the hazard warning system by moving the hazard warning switch button to the ON position.
Check for battery voltage at the inoperative (right or left) turn signal circuit cavity of the instrument panel wire harness connector (Connector C2)
for the instrument cluster. There should be a switching (ON and OFF) battery voltage signal.
If OK, replace the faulty turn signal indicator bulb.
If not OK, repair the open (right or left) turn signal circuit to the left multi-function switch as required.
