ABS/TCS
Abnormal Battery VoltageDIAGNOSTIC 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. Check terminals for damage or loose connections. Then reconnect connector.
2. Carry out self-diagnosis again. 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.
2. Check voltage between ABS actuator and electric unit (control unit) connector terminal 15 and ground. Does battery voltage exist when ignition switch is turned ON?
Yes >>GO T) 4.
No >>GO TO 5.
4. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND ABS/TCS
Is ground circuit OK?
OK >> Check ABS actuator and electric unit (control unit) pin terminals for damage or the connection of ABS actuator and electric unit (control unit) harness connector. Reconnect ABS actuator and electric unit (control unit) harness connector. Then retest.
NG >>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 45 (Engine control) for ABS actuator and electric unit (control unit). Refer to "POWER SUPPLY ROUTING CIRCUIT". Power Distribution
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 ON position.
2. Check continuity between battery and ABS actuator and electric unit (control unit) connector terminal 15.
Does continuity exist?
Yes >>Check 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.
