How To Erase Self Diagnostic Result
- After erasing DTC memory, start engine and drive vehicle at 30 km/h (19 MPH) or more for approximately 1 minute as the final inspection, and make sure that the ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp turn OFF. CAUTION: If memory cannot be erased, perform applicable diagnosis. NOTE: When the wheel sensor malfunctions, after inspecting the wheel sensor system, the ABS warning lamp, SLIP indicator lamp and brake warning lamp will not turn OFF even when the system is normal, unless the vehicle is driven at approximately 30 km/h (19 MPH) or more for approximately 1 minute. Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake fluid level switch operation (when brake fluid is insufficient). VDC OFF switch should not stay in ON position.
ACTIVE TEST MODE
| CAUTION | Do not perform active test while driving vehicle. Make sure to completely bleed air from brake system. The active test cannot be performed with the ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp or brake warning lamp on. ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp and brake warning lamp turn on during active test. |
Note. When active test is performed while depressing the pedal, the pedal depression amount will change. This is normal. "TEST IS STOPPED" is displayed 10 seconds after operation start. After "TEST IS STOPPED" is displayed, to perform test again, touch BACK.
