DTC DETECTION LOGIC

POSSIBLE CAUSE

NOTE:

Confirm if DTC is PAST or CRNT. If DTC is CRNT, proceed with Diagnosis Procedure. If DTC is PAST, clear

DTC. Do not replace the ABS actuator and electric unit (control unit) for a PAST DTC.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn the ignition switch OFF

and wait at least 10 seconds before conducting the next test.

>> GO TO 2.

2.

CHECK DTC DETECTION

With CONSULT

1. Turn the ignition switch OFF.

NOTE:

Wait at least 10 seconds after turning ignition switch OFF.

2. Start the engine.

NOTE:

Wait at least 10 seconds after start the engine.

3. Perform self-diagnosis for “ABS”.
Is DTC “C1113”, “C1145” or “C1146” detected?

YES-1 >> “C1113”, “C1145”, or “C1146” is displayed by “CRNT”: Proceed to 

BRC-85, "Diagnosis Proce-

dure"

.

YES-2 >> “C1113”, “C1145”, and “C1146” are displayed by “PAST”: INSPECTION END (Erase the memory

of self-diagnosis results.)

NO-1 >> To check malfunction symptom before repair: Refer to 

GI-45, "Intermittent Incident"

.

NO-2 >> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000012199691

1.

CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY AND GROUND CIR-

CUIT

Check the ABS actuator and electric unit (control unit) power supply and ground circuit. Refer to 

BRC-129,

"Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair / replace harness, connector, fuse, or fusible link.

2.

CHECK CONNECTOR

1. Turn the ignition switch OFF.

2. Check the ABS actuator and electric unit (control unit) harness connector for disconnection or looseness.

3. Check the yaw rate/side/decel G sensor harness connector for disconnection or looseness.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair / replace harness or connector, securely lock the connector, and GO TO 3.

3.

PERFORM SELF-DIAGNOSIS

With CONSULT

1. Turn the ignition switch OFF.

NOTE:

Wait at least 10 seconds after turning ignition switch OFF.

2. Start the engine.

NOTE:

Wait at least 10 seconds after start the engine.

3. Perform self-diagnosis for “ABS”.
Is DTC “C1113”, “C1145” or “C1146” detected?

YES

>> GO TO 4.

NO

>> INSPECTION END

4.

CHECK YAW RATE/SIDE/DECEL G SENSOR POWER SUPPLY CIRCUIT

1. Turn the ignition switch OFF.

2. Disconnect ABS actuator and electric unit (control unit) harness connector.

3. Disconnect yaw rate/side/decel G sensor harness connector.

4. Check the continuity between yaw rate/side/decel G sensor harness connector and ABS actuator and

electric unit (control unit) harness connector.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair / replace harness or connector.

5.

CHECK YAW RATE/SIDE/DECEL G SENSOR GROUND CIRCUIT

Check the continuity between yaw rate/side/decel G sensor harness connector and ABS actuator and electric

unit (control unit) harness connector.

3. Turn the ignition switch ON.

NOTE:

Never start the engine.

4. Select “ABS”, “DATA MONITOR” and “DECEL G-SEN” in order.

5. Move yaw rate/side/decel G sensor as shown in the figure to

check the output before and after moving the sensor.

Is the inspection result normal?

YES

>> GO TO 9.
