Description

INFOID:0000000004212635

The wheel sensors detect wheel speed and transmit the signals to the brake ECU. These signals are used for

control of the ABS control system. Each of the front and rear rotors has 48 serrations.

When the rotors rotate, the magnetic field generated by the permanent magnet in the wheel sensor induces an

AC voltage.

Since the frequency of this AC voltage changes in direct proportion to the speed of the rotor, the frequency is

used by the ECU to detect the speed of each wheel.

DTCs C1271 and C1272 can be deleted when the wheel sensor sends a wheel speed signal or the Test Mode

ends. DTCs C1271 and C1272 are output only in the Test Mode.

DTC Logic

INFOID:0000000004212636

NOTE:

• DTCs C0200 and C1271 are for the front wheel sensor RH.

• DTCs C0205 and C1272 are for the front wheel sensor LH.

• The brake warning light comes on when wheel sensor malfunctions are detected in two or more wheels.

Diagnosis Procedure

INFOID:0000000004212637

CAUTION:

When replacing the brake ECU, perform initialization of linear solenoid valve and calibration.

1.

CHECK MASTER CYLINDER PRESSURE SENSOR

Check master cylinder pressure sensor. Refer to 

BRC-11, "TEST MODE PROCEDURE"

.

>> GO TO 2.

2.

CHECK HARNESS AND CONNECTOR (MOMENTARY INTERRUPTION)

Using the “DATA MONITOR” of CONSULT-III, check for any momentary interruption in the wire harness and

connector corresponding to a DTC.

ABS/VDC:

Result

NOTE:

Perform the above inspection before removing the sensor and connector.

A

>> GO  TO  3.

B

>> GO  TO  11.

C

>> GO  TO  6.

3.

READ VALUE OF CONSULT-III (FRONT WHEEL SENSOR)

1. Turn the ignition switch OFF.

2. Connect the CONSULT-III.

3. Turn the ignition switch ON (READY).

4. Select the “DATA MONITOR” on the CONSULT-III.

ABS/VDC:

5. Check that these is no difference between the speed value output from the wheel sensor displayed on the

CONSULT-III and the speed value displayed on the speedometer when driving the vehicle.

NOTE:

Factors that affect the indicated vehicle speed include tire size, tire inflation, and tire wear. The speed indi-

cated on the speedometer has an allowable margin of error. This can be tested using speedometer tester

(calibrated chassis dynamometer). For details about testing and the margin of error, see the reference

chart.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 6.
