DTC CONFIRMATION PROCEDURE

1.

CHECK SELF DIAGNOSTIC RESULT

 With 

CONSULT.

1. Turn the ignition switch ON.

2. Perform “Self Diagnostic Result”.
Is DTC C1197 detected?

YES

>> Proceed to diagnosis procedure. Refer to 

BRC-103, "Diagnosis Procedure"

.

NO

>> Inspection End.

Diagnosis Procedure

INFOID:0000000011280632

Regarding Wiring Diagram information, refer to 

BRC-55, "Wiring Diagram"

.

1.

CHECK BRAKE BOOSTER

1. Turn the ignition switch OFF.

2. Check brake booster. Refer to 

BR-10, "Inspection"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace brake booster. Refer to 

BR-31, "Removal and installation"

.

2.

CHECK VACUUM PIPING

Check vacuum piping. Refer to 

BR-33, "Exploded View"

.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace vacuum piping. Refer to 

BR-33, "Removal and Installation"

.

3.

CHECK VACUUM SENSOR CIRCUIT

1. Disconnect vacuum sensor harness connector.

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

3. Check continuity between vacuum sensor harness connector and ABS actuator and electric unit (control

unit) harness connector.

4. Check continuity between vacuum sensor harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace malfunctioning components.

4.

CHECK TERMINAL

• Check vacuum sensor pin terminals for damage or loose connection with harness connector.

• Check ABS actuator and electric unit (control unit) pin terminals for damage or loose connection with har-

ness connector.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> Repair or replace malfunctioning components.

5.

REPLACE VACUUM SENSOR

With CONSULT

1. Connect ABS actuator and electric unit (control unit) harness connector.

2. Replace vacuum sensor. Refer to 

BR-31, "Exploded View"

.

CAUTION:

Always replace brake booster because vacuum sensor cannot be disassembled.

3. Erase “Self Diagnostic Result” of “ABS”.

4. Turn the ignition switch OFF.

5. Start engine.

6. Perform “Self Diagnostic Result” of “ABS”.
Is DTC “C1197” detected?

YES

>> Replace ABS actuator and electric unit (control unit). Refer to 

BRC-134, "Removal and Installa-

tion"

.

NO

>> Inspection End.
