Note 1:Brake warning lamp will turn on in case of operating parking brake (switch turned on) or of actuating brake fluid level switch
(brake fluid is insufficient).
Note 2:After starting engine, turn OFF.
1. Make sure ABS warning lamp, VDC OFF indicator lamp (when VDC OFF switch is OFF), and SLIP indica- tor lamp turn on approximately 2 second, and brake warning lamp turns on when ignition switch is turned
ON. If they do not, check VDC OFF indicator lamp and then VDC OFF switch. Refer to BRC-48, "
Compo-
nent Inspection". Check CAN communications. Refer to “CAN Communication Inspection”. If there are no
errors with VDC OFF switch and CAN communication system, check combination meter. Refer to DI-5
.
2. Make sure ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp turn off approximately 2 sec- ond after turn ignition switch ON, and brake warning lamp turns off after engine starts. If lamps do not turn
off, perform self-diagnosis.
3. With engine running, make sure VDC OFF indicator lamp turns on and off when VDC OFF switch is turned ON and OFF. If indicator lamp status does not correspond to switch operation, check the VDC OFF
switch system. Refer to BRC-48, "
Component Inspection".
4. Make sure ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off 2 seconds after engine is started. If ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp have not turned
off 10 seconds after engine has been started, perform self-diagnosis of ABS actuator and electric unit
(control unit).
5. After performing the self-diagnosis, be sure to erase the error memory. Refer to BRC-26, "
Self-Diagnosis".
NOTE:
Brake warning lamp will turn ON in case of parking brake operation (when switch is ON) or of brake fluid level
switch should not stay “ON” position.
