“C1142” detected?
YES >> Proceed to diagnosis procedure. Refer to BRC-108, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003766955
1.CHECK STOP LAMP SWITCH
Check stop lamp switch. Refer to BRC-99, "
Diagnosis Procedure".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace malfunction component.
2.CHECK DATA MONITOR
Check pressure sensor signal. Refer to BRC-108, "
Component Inspection".
Is the inspection result normal?
YES >> GO TO 3.
NO >> Check brake pedal, brake booster, and master cylinder for mount play, looseness, brake system
fluid leakage, etc.
- Brake pedal: Refer to BR-6, "
Inspection and Adjustment".
- Brake booster: Refer to BR-12, "
Inspection".
- Brake master cylinder: Refer to BR-11, "
Inspection".
3.ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) SELF-DIAGNOSIS
Perform ABS actuator and electric unit (control unit) self-diagnosis.
Is any item indicated on the self-diagnosis display?
YES >> Replace ABS actuator and electric unit (control unit).
NO >> Check ABS actuator and electric unit (control unit) pin terminals for damage or loose connection
with harness connector. If any items are damaged, repair or replace damaged parts.
Component InspectionINFOID:0000000003766956
1.CHECK DATA MONITOR
On “DATA MONITOR”, select “PRESS SENSOR” and check the brake fluid pressure.

DTC CONFIRMATION PROCEDURE
1.DTC REPRODUCTION PROCEDURE
1. Turn the ignition switch ON.
2. Perform ABS actuator and electric unit (control unit) self-diagnosis.
Is DTC
“C1145” or “C1146” detected?
YES >> Proceed to diagnosis procedure. Refer to BRC-113, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003766968
CAUTION:
Sudden turns (such as spin turns, acceleration turns), drifting, etc., when VDC function is off (VDC
OFF switch “ON”) may cause yaw rate/side G sensor system to indicate a malfunction. However, this
is not a malfunction, if normal operation can be resumed after restarting engine. Then erase memory
of self-diagnosis.
If vehicle is on turn-table at entrance to parking garage, or on other moving surface, VDC OFF indica-
tor lamp may illuminate and CONSULT-III self-diagnosis may indicate yaw rate sensor system mal-
function. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of
turn-table or other moving surface, and start the engine. Results will return to normal.
1.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect ABS actuator and electric unit (control unit) connector.
3. Disconnect yaw rate/side G sensor connector.
4. Check terminal for deformation, disconnection, looseness, etc.
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace damaged parts.
2.CHECK YAW RATE/SIDE G SENSOR POWER SUPPLY CIRCUIT
1. Turn the ignition switch ON.
CAUTION:
Never start the engine.
2. Check the voltage between yaw rate/side G sensor harness connector and ground.
3. Turn the ignition switch OFF.
4. Check the voltage between yaw rate/side G sensor harness connector and ground.
