INSPECTION PROCEDURE

NOTICE:

* When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using the Techstream and note

them down before removal.

* It is necessary to perform the initialization See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring

System/Testing and Inspection/Programming and Relearning/Initialization (from 12/2010) after the registration See:

Instrument Panel, Gauges and Warning Indicators/Tire Monitoring System/Testing and Inspection/Programming and

Relearning/Registration (from 12/2010) of the transmitter IDs into the tire pressure warning ECU if the ECU and/or one of

the valve and transmitters have been replaced.

PROCEDURE

1. CHECK DTC OUTPUT (C2176/76)

(a) Clear the DTC See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring System/Testing and Inspection/Reading and

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

(b) Turn the ignition switch off.

(c) Turn the ignition switch on (IG) and check for DTCs See: Instrument Panel, Gauges and Warning Indicators/Tire Monitoring

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

OK:

DTC C2176/76 is not output.

C0200/31,C0205/32,C1235/35,C1236/36,C1271/71,C1272/72,C1275/75,C1276/76: Right Front Wheel Speed Sensor Signal Malfunction

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.
