- Trouble Symptom Chart
- Symptom Procedures
- Inspection Procedure 1: Scan tool MB991958 communication with ASC system is impossible
- Inspection Procedure 2: Brake warning light stays ON with the parking brake lever released (ABS warning light is OFF)
- Inspection Procedure 3: When the ignition switch is turned to the "ON" position (engine stopped), the ABS warning light does not illuminate
- Inspection Procedure 4: Brake warning light does not illuminate when the ignition switch is turned to ON position (engine stopped)
- Inspection Procedure 5: ABS warning light stays ON after the engine is started
- Inspection Procedure 6: ASC warning light stays ON after the engine is started
- Inspection Procedure 7: ASC OFF light stays ON after the engine is started
- Inspection Procedure 8: The stability control/TCL system cannot be disabled when ASC OFF switch is pressed for 3 seconds or more to turn the system OFF
- Inspection Procedure 9: Abnormality in brake operation
- Inspection Procedure 10: Abnormality in active stability control system operation
