Turn Signal On Chime Does Not Function, But Turn Signals Function Properly

WARNING: This page is about a different car, the 1998 Pontiac Sunfire. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect instrument cluster connector. Disconnect radio Gray 10-pin connector C2. Disconnect multi-function alarm module connector C1. Disconnect cruise control module connector. Disconnect Powertrain Control Module (PCM) Black 80-pin connector C2. Using DVOM, check voltage between multi-function alarm module harness connector C1, terminal "A" (Dark Green/White wire) and ground. If zero volts exist, go to next step. If zero volts does not exist, go to step 3).
Using DVOM, check resistance between multi-function alarm module harness connector C1, terminal "A" (Dark Green/White wire) and ground. If resistance is infinite, go to step 4). If resistance is not infinite, go to step 5).
Repair short to voltage in Dark Green/White wire between instrument cluster, cruise control module, radio connector C2, multi-function alarm module connector C1 and PCM connector C2. See WIRING DIAGRAMS . Recheck system operation.
Using DVOM, check resistance between multi-function alarm module harness connector C1, terminal "A" (Dark Green/White wire) and PCM connector C2, terminal No. 16 (Dark Green/White wire). If resistance is 0-2 ohms, go to step 6). If resistance is not 0-2 ohms, go to step 7).
Repair short to ground in Dark Green/White wire between instrument cluster, cruise control module, radio connector C2, multi-function alarm module connector C1 and PCM connector C2. See WIRING DIAGRAMS . Recheck system operation.
Replace multi-function alarm module. Recheck system operation. If system is still not operating properly, replace PCM. See appropriate REMOVE/INSTALL/OVERHAUL article in ENGINE PERFORMANCE section:
- REMOVE/INSTALL/OVERHAUL - 2.2L
- REMOVE/INSTALL/OVERHAUL - 2.4L
Repair open in Dark Green/White wire between multi-function alarm module and PCM connector C2. Recheck system operation.
