TROUBLE DIAGNOSIS


Basic Inspection


BASIC INSPECTION 1: BRAKE FLUID LEVEL, LEAK INSPECTION AND BRAKE PAD
1. Check fluid level in brake reservoir tank. If fluid level is low, refill brake fluid. Refer to Procedures.
2. Check for leakage in brake tubes or hoses and around ABS actuator and electric unit (control unit). If there is leaking or seeping fluid, check the following items.
- If the brake tube connections at ABS actuator and electric unit (control unit) are loose, tighten flare nuts to the specified torque. Then inspect again and confirm that there is no leakage.
- If flare nuts or screws of ABS actuator and electric unit (control unit) are damaged and loose, replace damaged parts. Then inspect again and confirm that there is no leakage.
- If there is leakage at any location other than ABS actuator and electric unit (control unit) connections, wipe away leakage with clean cloth. Then inspect again and confirm that there is no leakage.
- If there is leakage from ABS actuator and electric unit (control unit), wipe away leakage with clean cloth.
Then inspect again. If there is still leakage, replace ABS actuator and electric unit (control unit).

CAUTION:
ABS actuator and electric unit (control unit) cannot be disassembled.
3. Check brake disc rotor and pads.
- Front disc rotor: Refer to Disassembly and Assembly of Brake Caliper Assembly.
- Front brake pad: Refer to Procedures.
- Rear disc rotor: Refer to Disassembly and Assembly of Brake Caliper Assembly.
- Rear brake pad: Refer to Procedures.

BASIC INSPECTION 2: LOOSENESS OF POWER SYSTEM TERMINALS AND BATTERY
Check battery for looseness on battery positive/negative terminals and ground connection. Also make sure battery voltage does not drop and alternator is normal.

BASIC INSPECTION 3: ABS WARNING LAMP, BRAKE WARNING LAMP, VDC OFF INDICATOR

LAMP AND SLIP INDICATOR LAMP

ON and OFF Timing for Warning Lamp and Indicator Lamp





Check the following items when unsuitable for an above condition.
- ABS warning lamp: CAN Communication Circuit.
- Brake warning lamp: CAN Communication Circuit, Brake Fluid Level Switch Circuit BRC-53, "Parking Brake Switch Circuit".
- VDC OFF indicator lamp: CAN Communication Circuit, VDC OFF Switch Circuit.
- SLIP indicator lamp: CAN Communication Circuit.
If malfunction is not found, refer to Warning Lamp and Indicator Lamp Circuit.
