Turn Signal Indicators Inoperative - Left
- If lighting diagnostic system check was performed, go to next step. If lighting diagnostic system check was not performed, go to LIGHTING DIAGNOSTIC SYSTEM CHECK .
- If left turn signal exterior lights operate properly, go to next step. If left turn signal exterior lights do not operate properly, diagnose inoperative turn signals. See EXTERIOR LIGHTS article in WIRING DIAGRAMS.
- Turn ignition off. Connect scan tool to Data Link Connector (DLC). See Figure . Turn ignition on. Move turn signal lever to left turn position. Using scan tool, select Instrument Panel Cluster (IPC) data list. Monitor LEFT TURN SIGNAL status. If LEFT TURN SIGNAL status is not ON, go to next step. If LEFT TURN SIGNAL status is ON, go to step 6 .
- Check for open or high resistance in Light Blue wire between IPC connector C1 terminal B12 and splice S208. See Figure . S208 is located approximately 36.5" (92.7 cm) from Instrument Panel Integration Module (IPM) connector C1. See Figure . If circuit is okay, go to next step. If faulty circuit is found and repaired, go to step 8 .
- Check for poor connections at IPC connector. If connections are okay, go to next step. If faulty connections are found and repaired, go to step 8 .
- Turn ignition off. Connect scan tool to Data Link Connector (DLC). See Figure . Turn ignition on. Using scan tool, select Instrument Panel Cluster (IPC) SPECIAL FUNCTIONS and perform DISPLAY(S) TEST. Monitor left turn signal indicator during test. If left turn signal indicator comes on during test and then turns off, check for intermittent circuits and connections for left turn signal. If left turn signal indicator does not come on during test and then turn off, go to next step.
- Replace IPC. See INSTRUMENT PANEL CLUSTER under REMOVAL & INSTALLATION. After repairs, go to next step.
- After repairs, recheck operation of indicator. If indicator operates properly, repair is complete. If indicator does not operate properly, go to step 2 .
