Turn Signal Indicator: Testing and Inspection
Hard Wired Lamp Diagnosis
Each of the lamps found upon a hard wired circuit input to the instrument cluster for proper operation. The following procedures will help to diagnose
conditions that may cause an inoperative hard wired lamp circuit condition.
WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAG BEFORE ATTEMPTING ANY STEERING WHEEL,
STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER
PRECAUTIONS COULD RESULT IN ACCIDENTAL AIR-BAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
The diagnosis found here addresses an inoperative turn signal indicator lamp condition. For any other turn signal problem, refer to Turn Signal and
Hazard Warning Systems Diagnosis for further 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.
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 cluster wire harness connector B. There should be a
switching (on and off) battery voltage signal. If OK, replace the faulty (right or left) turn signal indicator lamp bulb. If not OK, repair the open
(right or left) turn signal circuit to the turn signal/hazard warning (multi-function) switch as required.
