Inspection Procedure

NOTE: When replacing the master cylinder solenoid, perform zero point calibration (See CALIBRATION ).
  1. CHECK TIRE SIZE 
    1. Check tire size and condition of all 4 wheels.

    OK: Condition of all 4 wheels is normal and tire size is same. 

    NG: REPLACE TIRES SO THAT ALL 4 TIRES ARE SAME SIZE 

    OK: Go to next step 

  2. INSPECT SPEED SENSOR ROTOR 
    1. Check the front speed sensor rotors (See DTC C0200/31 FRONT SPEED SENSOR RH CIRCUIT; DTC C0205/32 FRONT SPEED SENSOR LH CIRCUIT; DTC C1235/35 FOREIGN OBJECT IS ATTACHED ON TIP OF FRONT SPEED SENSOR RH; DTC C1236/36 FOREIGN OBJECT IS ATTACHED ON TIP OF FRONT SPEED SENSOR LH ) and rear speed sensor rotors (See DTC C0210/33 REAR SPEED SENSOR RH CIRCUIT; DTC C0215/34 REAR SPEED SENSOR LH CIRCUIT; DTC C1238/38 FOREIGN OBJECT IS ATTACHED ON TIP OF REAR SPEED SENSOR RH; DTC C1239/39 FOREIGN OBJECT IS ATTACHED ON TIP OF REAR SPEED SENSOR LH ).

    RESULT REFERENCE

    Result Proceed to
    OK A
    NG Front speed sensor B
    Rear speed sensor C

    B: REPLACE FRONT AXLE HUB SUB-ASSEMBLY (SPEED SENSOR ROTOR)  (See DISASSEMBLY )

    C: REPLACE REAR AXLE HUB AND BEARING ASSEMBLY (SPEED SENSOR ROTOR)  (See INSPECTION )

    A: Go to next step 

  3. INSPECT SPEED SENSOR 
    1. Check the front speed sensor circuit (See DTC C0200/31 FRONT SPEED SENSOR RH CIRCUIT; DTC C0205/32 FRONT SPEED SENSOR LH CIRCUIT; DTC C1235/35 FOREIGN OBJECT IS ATTACHED ON TIP OF FRONT SPEED SENSOR RH; DTC C1236/36 FOREIGN OBJECT IS ATTACHED ON TIP OF FRONT SPEED SENSOR LH ) and rear speed sensor circuit (See DTC C0210/33 REAR SPEED SENSOR RH CIRCUIT; DTC C0215/34 REAR SPEED SENSOR LH CIRCUIT; DTC C1238/38 FOREIGN OBJECT IS ATTACHED ON TIP OF REAR SPEED SENSOR RH; DTC C1239/39 FOREIGN OBJECT IS ATTACHED ON TIP OF REAR SPEED SENSOR LH ).

    Result 

    RESULT REFERENCE

    Result Proceed to
    OK A
    NG Front speed sensor B
    Rear speed sensor C

    B: REPLACE FRONT SPEED SENSOR  (See FRONT SPEED SENSOR )

    C: REPLACE REAR SPEED SENSOR  (See REMOVAL )

    A: Go to next step 

  4. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU - SPEED SENSOR) 
    1. Check the front speed sensor circuit (See DTC C0200/31 FRONT SPEED SENSOR RH CIRCUIT; DTC C0205/32 FRONT SPEED SENSOR LH CIRCUIT; DTC C1235/35 FOREIGN OBJECT IS ATTACHED ON TIP OF FRONT SPEED SENSOR RH; DTC C1236/36 FOREIGN OBJECT IS ATTACHED ON TIP OF FRONT SPEED SENSOR LH ) and rear speed sensor circuit (See DTC C0210/33 REAR SPEED SENSOR RH CIRCUIT; DTC C0215/34 REAR SPEED SENSOR LH CIRCUIT; DTC C1238/38 FOREIGN OBJECT IS ATTACHED ON TIP OF REAR SPEED SENSOR RH; DTC C1239/39 FOREIGN OBJECT IS ATTACHED ON TIP OF REAR SPEED SENSOR LH ).

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  5. RECONFIRM DTC 
    1. Clear the DTCs (See DTC CHECK/CLEAR ).
    2. Drive the vehicle at a speed of approximately 32 km/h (20 mph) or more for 60 seconds or more.
    3. Check if the same DTCs are output (See DTC CHECK/CLEAR ).

    HINT:

    Reinstall the sensors, connectors, etc. and restore the previous vehicle conditions before rechecking for DTCs.

    Result 

    RESULT REFERENCE

    Result Proceed to
    DTC is output. A
    DTC is not output. B

    B: USE SIMULATION METHOD TO CHECK  (See HOW TO PROCEED WITH TROUBLESHOOTING )

    A: REPLACE MASTER CYLINDER SOLENOID  (See DISASSEMBLY )
