TROUBLE DIAGNOSIS


Basic Inspection


BRAKE FLUID LEVEL, FLUID LEAK, AND BRAKE PAD INSPECTION
1. Check fluid level in the brake fluid reservoir. If fluid level is low, add fluid.
2. Check the brake piping and around the ABS actuator and electric unit (control unit) for leaks. If there is leaking or seeping fluid, check the following items.
- If ABS actuator and electric unit (control unit) connection is loose, tighten the piping to the specified torque and recheck for leaks.
- If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) threads, replace the damaged part and recheck for leaks.
- When there is fluid leaking or seeping from a fluid connection, use a clean cloth to wipe off the fluid and recheck for leaks. If fluid is still seeping out, replace the damaged part. If the fluid is leaking at the ABS actuator and electric unit (control unit), replace the ABS actuator and electric unit (control unit) assembly.

CAUTION:
The ABS actuator and electric unit (control unit) cannot be disassembled and must be replaced as an assembly.
3. Check the brake pads for excessive wear.

POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure the battery positive cable, negative cable and ground connection are not loose. In addition, make sure the battery is sufficiently charged.

ABS WARNING LAMP INSPECTION
1. Make sure ABS warning lamp turns on for approximately 2 seconds when the ignition switch is turned ON.
If it does not, check CAN communications. If there are no errors with the CAN communication system, replace the combination meter. Refer to Removal And Installation.
2. Make sure the lamp turns off approximately 2 seconds after the ignition switch is turned ON. If the lamp does not turn off, conduct self-diagnosis of ABS actuator and electric unit (control unit). If no malfunctions are detected in self-diagnosis, replace combination meter. Refer to Removal And Installation.
3. After conducting the self-diagnosis, be sure to erase the error memory. Refer to "CONSULT-III Function (ABS)" Scan Tool Testing and Procedures
