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. Start the engine.

2. Drive the vehicle at approx. 50 km/h (31 MPH) or more for approx. 2 minutes.

3. Stop the vehicle.

4. Turn the ignition switch OFF.

NOTE:

Wait at least 10 seconds after turning ignition switch OFF.

5. Start the engine.

NOTE:

Wait at least 10 seconds after start the engine.

6. Perform self-diagnosis for “ABS”.
Is DTC “C1115” detected?

YES-1 >> “CRNT” is displayed: Proceed to 

BRC-88, "Diagnosis Procedure"

.

YES-2 >> “PAST” is displayed: 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:0000000012199693

CAUTION:

Never check between wheel sensor harness connector terminals.

1.

CHECK TIRE

Check the tire air pressure, wear and size. Refer to 

WT-47, "Tire Air Pressure"

.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Adjust air pressure or replace tire and GO TO 2.

2.

CHECK DATA MONITOR (1)

With CONSULT

1. Erase self-diagnosis result for “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. Select “ABS” and “DATA MONITOR”, check “FR LH SENSOR”, “FR RH SENSOR”, “RR LH SENSOR”

and “RR RH SENSOR”.

NOTE:

Set the “DATA MONITOR” recording speed to “10 msec”.

5. Read a value (wheel speed) of both normal wheel sensors and error-detecting wheel sensor. 

NOTE:

Vehicle must be driven after repair or replacement to erase the previous DTCs.

Note the difference at 50 km/h (31 MPH) between the wheel speed detected by the error detecting wheel sen-

sor and the maximum/minimum wheel speed detected by the normal wheel sensors, is the difference within

5%, respectively?

YES

>> GO TO 3.

NO

>> GO TO 4.

3.

PERFORM SELF-DIAGNOSIS (1)

With CONSULT

1. Stop the vehicle.

2. Turn the ignition switch OFF.

NOTE:

Wait at least 10 seconds after turning ignition switch OFF.

3. Start the engine.

NOTE:

Wait at least 10 seconds after start the engine.

4. Perform self-diagnosis for “ABS”.
Is DTC “C1115” detected?

YES

>> GO TO 4.

NO

>> INSPECTION END

4.

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 5.

NO

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

5.

CHECK WHEEL SENSOR AND SENSOR ROTOR

1. Turn the ignition switch OFF.

2. Disconnect wheel sensor harness connector.

3. Remove dust and foreign matter adhered to the wheel sensor and sensor rotor with a vacuum dust collec-

tor through the wheel sensor mounting hole.

CAUTION:

Install wheel sensor with no backlash and float, and tighten the mounting bolt to the specified

torque.

sensor tester. The red SENSOR indicator should flash ON and OFF to indicate an output signal.

NOTE:

If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and

retest.

Does the ABS active wheel sensor tester detect a signal?

YES

>> GO TO 11.

NO

>> GO TO 8.

sor and the maximum/minimum wheel speed detected by the normal wheel sensors, is the difference within

5%, respectively?

YES

>> GO TO 9.

NO

>> GO TO 19.
