OK:

The speed value output from the speed sensor displayed on the Techstream is the same as the actual vehicle speed.

NG -- REPLACE ABS & TRACTION ACTUATOR ASSEMBLY

OK -- Continue to next step.

11. RECONFIRM DTC

(a) Clear the DTC See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and

Clearing Diagnostic Trouble Codes/DTC Check / Clear (to 12/2010).

(b) Start the engine.

(c) Drive the vehicle at the speed of 32 km/h (20 mph) or more for 60 seconds or more.

(d) Check that the same DTC is recorded See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and

Inspection/Reading and Clearing Diagnostic Trouble Codes/DTC Check / Clear (to 12/2010).

Result:

HINT

These DTCs may be stored due to a malfunction in the connector terminal connection, etc.

B -- INSPECT SPEED SENSOR TIP

A -- END

12. INSPECT SPEED SENSOR TIP

(a) Remove the front speed sensor See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Wheel Speed

Sensor/Service and Repair/Front Speed Sensor/Removal.

(b) Check the sensor tip.

OK:

No scratches or foreign matter on the sensor tip.

NOTICE:

Check the speed sensor signal after cleaning or replacement See: Brakes and Traction Control/Antilock Brakes / Traction

Control Systems/Testing and Inspection/Scan Tool Testing and Procedures/Test Mode Procedure (to 12/2010).

NG -- CLEAN OR REPLACE SPEED SENSOR

OK -- CLEAN OR REPLACE SPEED SENSOR ROTOR

C1276/76 - Abnormal Change in Output Signal of Front Speed Sensor LH (Test Mode DTC)

DESCRIPTION

The speed sensor detects wheel speed and transmits the appropriate signals to the skid control ECU. These signals are used for control of the ABS

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 speed sensor induces 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 skid control ECU to detect the speed of each wheel.

DTCs C1271/71, C1272/72, C1275/75 and C1276/76 are output only in the Test Mode.
