VDC AND TCS FUNCTIONS
VDC warning lamp in combination meter turns ON when a malfunction occurs in system [ABS actuator and
electric unit (control unit)]. The control is su spended for VDC and TCS functions. However, ABS and EBD
functions operate normally.
ABS FUNCTION
ABS warning lamp and SLIP indicator lamp in combination meter turn ON when a malfunction occurs in sys-
tem [ABS actuator and electric unit (control unit)]. The control is suspended for VDC, TCS and ABS functions.
However, EBD functions operate normally.
EBD FUNCTION
ABS warning lamp, brake warning lamp and SLIP indicator lamp in combination meter turn ON when a mal-
function occurs in system [ABS actuator and electric unit (control unit)]. The control is suspended for VDC,
TCS, ABS and EBD functions.

YES-2 >> “C1101”, “C1102”, “C1103” or “C1104” is disp layed as “PAST”: Inspection End (Erase “Self Diag-
nostic Result” of “ABS”).
NO-1 >> To check malfunction symptom before repair: Refer to GI-42, "
Intermittent Incident".
NO-2 >> Confirmation after repair: Inspection End.
Diagnosis ProcedureINFOID:0000000012430855
CAUTION:
Never check between wheel sensor harness connector terminals.
1.CHECK WHEEL SENSOR
1. Turn the ignition switch OFF.
2. Check the wheel sensor for damage.
Is the inspection result normal?
YES >> GO TO 3.
NO >> GO TO 2.
2.REPLACE WHEEL SENSOR (1)
With CONSULT
1. Replace the wheel sensor.
- Front: Refer to BRC-140, "
FRONT WHEEL SENSOR : Removal and Installation".
- Rear: Refer to BRC-141, "
REAR WHEEL SENSOR : Removal and Installation".
2. Erase “Self Diagnostic Result” of “ABS”.
3. Turn the ignition switch OFF → ON → OFF.
NOTE:
Wait at least 10 seconds after turning ignition switch OFF or ON.
4. Start the engine.
5. Drive the vehicle at approx. 50 km/h ( 31 MPH) or more for approx. 2 minutes.
NOTE:
Vehicle must be driven after repair or replacement to erase the previous DTCs.
6. Stop the vehicle.
7. Turn the ignition switch OFF. NOTE:
Wait at least 10 seconds after turning ignition switch OFF.
8. Start the engine. NOTE:
Wait at least 10 seconds after starting the engine.
9. Perform “Self Diagnostic Result” of “ABS”.
Is DTC
“C1101”, “C1102”, “C1103” or “C1104” detected?
YES >> GO TO 3.
NO >> Inspection End.
3.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Check the ABS actuator and electric unit (contro l unit) harness connector for disconnection or looseness.
3. Check the wheel sensor harness c onnector for disconnection or looseness.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair / replace harness or connector, securely lock the connector, and GO TO 4.
4.PERFORM SELF-DIAGNOSIS (1)
With CONSULT
1. Erase “Self Diagnostic Result” of “ABS”.
2. Turn the ignition switch OFF → ON → OFF.
NOTE:
Wait at least 10 seconds after turning ignition switch OFF or ON.
3. Start the engine.
4. Drive the vehicle at approx. 50 km/h ( 31 MPH) or more for approx. 2 minutes.
NOTE:
Vehicle must be driven after repair or replacement to erase the previous DTCs.
