ABS/TCS

Abnormal Battery Voltage

DIAGNOSTIC PROCEDURE
With CONSULT-II: Malfunction code No. C1109
Without CONSULT-II: Malfunction code No. 57

1. INSPECTION START





ABS actuator and electric unit (control unit) power supply and ground circuit inspection.
>> GO TO 2.

2. CHECK CONNECTOR
1. Disconnect ABS actuator and electric unit (control unit) connector E125. Check terminals for deformation, disconnection, looseness or damage. Then reconnect connector.
2. Repeat self-diagnosis.
Does warning lamp activate again?
YES >> GO TO 3.
NO >> Inspection End.

3. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY CIRCUIT





1. Disconnect ABS actuator and electric unit (control unit) connector E125.
2. Check voltage between ABS actuator and electric unit (control unit) connector E125 terminal 15 (GY) and ground.
Does battery voltage exist when ignition switch is turned ON?
YES >> GO TO 4.
NO >> GO TO 5.

4. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND
Refer to "ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND".
Is ground circuit OK?
YES >> Check ABS actuator and electric unit (control unit) pin terminals for damage and the connection of ABS actuator and electric unit (control unit) harness connector. Reconnect ABS actuator and electric unit (control unit) harness connector. Then retest.
NO >> Check the following.
- Harness connector E125
- Harness for open or short between ABS actuator and electric unit (control unit) and ground. If NG, repair harness or connectors.

5. CHECK FUSE
Check 10A fuse 49 for ABS actuator and electric unit (control unit). Refer to "POWER SUPPLY ROUTING CIRCUIT".
Is fuse OK?
YES >> GO TO 6.
NO >> If fuse is blown, be sure to eliminate cause of problem before installing new fuse.

6. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY CIRCUIT
1. Turn ignition switch to OFF position.
2. Check continuity between battery and ABS actuator and electric unit (control unit) connector E125 terminal 15 (GY).
Does continuity exist?
YES >> Check battery. Refer to "BATTERY".
NO >> Check the following.
- Harness connector E125
- Harness for open or short between ABS actuator and electric unit (control unit) and fuse. If NG, repair harness or connectors.
