TROUBLE DIAGNOSIS

Basic InspectionBFS000E7
BRAKE FLUID LEVEL, LEAKAGE AND BRAKE PAD
1. Check fluid level in the brake fluid reservoir tank. Refill the brake fluid if fluid level is low.
2. Check the area around the brake piping and actuator for leakage. If leakage or oozing is detected, check
as follows:

If ABS actuator and electric unit (control unit) connections are loose, tighten connections to the speci-
fied torque. Check again for leakage, and make sure that there is no fluid leakage.

If the flare nuts at the connections and the threads of the actuator are damaged, replace the damaged
parts. Then check again for leakage, and make sure that there is no fluid leak.

If leakage or oozing is detected on parts other than actuator connections, wipe with a clean cloth and
check again. If there is still leakage or oozing, replace the damaged part.

If leakage or oozing is detected on actuator body, wipe with a clean cloth and check again. If there is
still leakage or oozing, replace ABS actuator and electric unit (control unit).
CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake pad for wear. Refer to BR-26, "
PAD WEAR INSPECTION" , “FRONT DISC BRAKE”, BR-33,
"PAD WEAR INSPECTION" , “REAR DISC BRAKE”.
POWER SUPPLY CIRCUIT TERMINAL LOOSENESS AND BATTERY
Check battery for looseness on the battery positive/negative terminal and ground connection. Also make sure
that battery voltage does not drop.
INSPECTION OF ABS WARNING LAMP, BRAKE WARNING LAMP, VDC OFF INDICATOR LAMP,
AND SLIP INDICATOR LAMP
×: ON –: OFF
Note 1: Turns off after engine start
Note 2: The brake warning lamp turns on during parking brake operation (when switch is on) and brake fluid level sensor operation
(insufficient brake fluid).
1. Make sure that when the ignition switch is turned ON, the ABS warning lamp, VDC OFF indicator lamp
(when VDC OFF switch is off), and SLIP indicator lamp turn on for approximately 1 second, and that the
brake warning lamp turns on. If they do not turn on, perform CAN communication system diagnosis. Refer
to BRC-81, "
CAN Communication System" . Be sure to check VDC OFF switch before checking VDC OFF
indicator lamp. Refer to BRC-81, "
VDC OFF SWITCH" . Check combination meter if there is no malfunc-
tion in CAN communication system and VDC OFF switch. Refer to DI-4, "
COMBINATION METERS" .
2. Check if the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off approximately
1 second after the ignition switch is turned ON, and if the brake warning lamp turns off after the engine is
started. If they do not turn off, perform self-diagnosis.
