(a) If the skid control ECU detects a malfunction, the ABS and/or BRAKE warning lights and the slip indicator lights come on in accordance with the trouble area to warn the driver.
HINT:
NOTICE:
If parts connected to the IG terminal circuit are damaged due to high voltage, DTCs may not be able to be output from the ABS warning light and slip indicator light by connecting SST to the DLC3. In this case, inspect the IG power source circuit.
2. WARNING LIGHT AND INDICATOR LIGHT CHECK
(a) Release the parking brake.
CAUTION:
When releasing the parking brake, set chocks to hold the vehicle for safety.
HINT:
When the parking brake is applied or the level of the brake fluid is low, the BRAKE warning light comes on.
(b) Check that the ABS warning light, BRAKE warning light and slip indicator light come on when the ignition switch is turned to ON, and go off in approximately 3 seconds.
