C1336

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1210/36,C1336/98: Zero Point Calibration of Yaw Rate Sensor Undone


DESCRIPTION

The skid control ECU receives signals from the yaw rate and G sensor via the CAN communication system.

The yaw rate sensor has a built-in G sensor.

If there is trouble in the bus lines between the yaw rate and G sensor and the CAN communication system, the DTCs U0123/62 (yaw rate sensor communication trouble) and U0124/95 (G sensor communication trouble) are stored.

INSPECTION PROCEDURE

NOTICE:
When replacing the master cylinder solenoid, perform zero point calibration Programming and Relearning.

HINT
When U0073/94, U0100/65, U0114/38, U0123/62, U0124/95, U0126/63 or U0130/68 is output together with C1210/36 or C1336/98, inspect and repair the trouble areas indicated by U0073/94, U0100/65, U0114/38, U0123/62, U0124/95, U0126/63 or U0130/68 first.

PROCEDURE

1. CHECK SENSOR INSTALLATION

(a) Check that the yaw rate and G sensor is installed properly.

OK:

The sensor is tightened to the specified torque.

The sensor is not tilted.

NG -- INSTALL YAW RATE AND G SENSOR CORRECTLY
OK -- Continue to next step.

2. PERFORM ZERO POINT CALIBRATION OF YAW RATE AND G SENSOR

(a) Perform the zero point calibration of the yaw rate and G sensor Programming and Relearning.

NEXT -- Continue to next step.

3. RECONFIRM DTC

(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

(b) Check if the same DTCs are output Reading and Clearing Diagnostic Trouble Codes.

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