Turn Signal Indicator: Testing and Inspection
The diagnosis found here addresses an inoperative turn signal indicator lamp condition. For any other turn signal problem, refer to Lighting and Horns
/Turn Signal and Hazard Warning Systems for diagnosis. If no turn signal or hazard warning system problem is found, the following procedure will help
locate a short or open in the indicator lamp circuit.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAG SYSTEMS BEFORE ATTEMPTING ANY STEERING
WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
1. Disconnect and isolate the battery negative cable. Remove the instrument cluster.
2. Connect the battery negative cable. Activate the hazard warning system by depressing the hazard warning switch button to the On position. Check
for battery voltage at the inoperative (right or left) turn signal indicator lamp circuit cavity of the instrument cluster wire harness connector. There
should be a switching (on and off) battery voltage signal. If OK, replace the faulty (right or left) indicator lamp bulb. If not OK, repair the open
circuit to the turn signal/ hazard warning (multi-function) switch as required.
