BRAKE/PARK BRAKE INDICATOR
The brake/park brake indicator illuminates when the parking brake is applied with the ignition switch turned to the ON position (Refer to PARK BRAKE SWITCH TEST table. The same lamp will also illuminate if one of the two (hydraulic or ABS) service brake systems fail when the brake pedal is applied.
| PROCEDURE | EXPECTED RESULTS |
|---|---|
| 1. Turn key to run wait till bulb check is complete | 1. Brake indicator lamps comes ON for a few seconds, then will turn OFF. |
| 2. Apply park brakes. | 2. Verify that the brake indicator lamp comes ON. |
| 3. Disengage the park brakes. | 3. Verify Brake indicator lamp turns OFF. |
| 4. Repeat steps 2 and 3 with key in OFF/ACC and LOCK positions. | 4. Brake indicator lamp should not come ON. |
| 5. In an Automatic Transmission vehicle apply park brakes, start the vehicle, press brake pedal and shift into reverse or drive. | 5. The brake indicator lamp should flash. (Move on to Step 7) |
| 6. In a Manual Transmission vehicle, start the vehicle with park brakes applied. | 6. The brake indicator lamp should start flashing. (Move on to Step 7) |
| 7. Drive the vehicle over 8 km/h (5 mph) with the park brake engaged. | 7. The park brake lamp should flash accompanied with a chime. |
PARK BRAKE SWITCH TEST
CHIME/BUZZER SYSTEM
The hard wired chime warning system inputs to the ElectroMechanical Instrument Cluster (EMIC), as well as other hard wired circuits for this system may be diagnosed and tested using conventional diagnostic tools and procedures. 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.
However, conventional diagnostic methods may not prove conclusive in the diagnosis of the EMIC, the Controller Area Network (CAN) data bus, or the electronic message inputs used by the EMIC to provide chime warning system service. The most reliable, efficient, and accurate means to diagnose the EMIC, the CAN data bus, and the electronic message inputs for the chime warning system requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic information.
| CONDITION | POSSIBLE CAUSES | CORRECTION |
|---|---|---|
| NO KEY-IN IGNITION WARNING CHIME, BUT OTHER CHIME FEATURES OK | 1. Driver door ajar switch sense circuit open. | 1. Check for continuity between the driver door ajar switch sense circuit connector and the instrument cluster connector. Repair the open driver door ajar switch sense circuit, if required. |
| 2. Key-in ignition switch sense circuit open. | 2. Check for continuity between the key-in ignition switch sense circuit connector and instrument cluster connector. Repair the open key-in ignition switch sense circuit, if required. | |
| 3. Key-in ignition switch ground circuit open. | 3. Check for continuity between the ground circuit cavity of the ignition switch connector and a good ground. Repair the open ground circuit, if required. | |
| 4. Faulty ignition switch. | 4. Check for continuity between the ground circuit terminal and the key-in ignition switch sense circuit terminal in the ignition switch connector. There should be continuity with a key in the ignition lock cylinder. Replace the faulty ignition switch, if required. | |
| NO EXTERIOR LAMPS-ON WARNING CHIME, BUT OTHER CHIME FEATURES OK | 1. Driver door ajar switch sense circuit open. | 1. Check for continuity between the driver door ajar switch sense circuit connector and the instrument cluster connector. Repair the open driver door ajar switch sense circuit, if required. |
| 2. Headlamp switch signal circuit open. | 2. Check for continuity between the headlamp switch output circuit connector and the instrument cluster connector. Repair the open headlamp switch signal circuit, if required. | |
| NO CHIMES AND OTHER INSTRUMENT CLUSTER FEATURES ERRATIC OR DISABLED | 1. Instrument cluster ground circuit(s) open. | 1. Check for continuity between the ground circuits of the instrument cluster connector and a good ground. Repair the open ground circuits(s), if required. |
| 2. Instrument cluster fused B(+) circuit(s) open. | 2. Check for battery voltage at the B(+) circuits of the instrument cluster connector. Repair the open fused B(+) circuit(s), if required. | |
| 3. Instrument cluster fused ignition switch output (run-start) circuit open. | 3. With the ignition switch in the On position, check for battery voltage at the fused ignition switch output (run-start) circuit of the instrument cluster connector. Repair the open fused ignition switch output (run-start) circuit, if required. | |
| 4. Faulty instrument cluster. | 4. Replace the faulty instrument cluster, if required. | |
| NO CHIMES, BUT ALL OTHER INSTRUMENT CLUSTER FEATURES OK | 1. Faulty instrument cluster. | 1. Replace the faulty instrument cluster, if required. |
FASTEN SEAT BELTS
To test the seat belt reminder function, perform the following
With the drivers seat belt unbuckled and fully retracted, turn the ignition to the ON position. The seat belt warning light will flash 4 - 8 times and the chime will sound 3 - 5 seconds, then remain lit. If the seat belt is not fastened, and the vehicle reaches a speed of 5 - 10 mph (8 - 16 kmh), the indicator light will flash 4 - 8 times and then remain lit while the chime sounds for 3 - 5 seconds. This will continue until the seatbelt is pulled from the retractor.
If the lamp does not light, verify the seat belt reminder function is enabled, for more information. Refer to STANDARD PROCEDURE . If the reminder function is enabled, check the connection at the seat belt retractor. Replace as necessary.
