BRAKE CONTROL: ELECTRONICALLY CONTROLLED BRAKE SYSTEM: C1240/95: Yaw Rate Sensor Discrimination

DTC C1240/95 - Yaw Rate Sensor Discrimination

DESCRIPTION

The skid control ECU determines if the yaw rate and acceleration sensor identification information sent via CAN communication matches the yaw rate and acceleration sensor identification information memorized by the skid control ECU.






INSPECTION PROCEDURE
NOTICE:
- When replacing the yaw rate and acceleration sensor, perform zero point calibration Programming and Relearning.
- When replacing the skid control ECU, perform initialization of linear solenoid valve and calibration Programming and Relearning.

PROCEDURE

1. CHECK PART NUMBER (YAW RATE AND ACCELERATION SENSOR)
(a) Check that the proper yaw rate and acceleration sensor is installed.
OK:
Proper yaw rate and acceleration sensor installed.
NG -- REPLACE YAW RATE AND ACCELERATION SENSOR
OK -- Continue to next step.

2. RECONFIRM DTC
(a) Clear the DTC Reading and Clearing Diagnostic Trouble Codes.
(b) Turn the engine switch on (IG).
(c) Check if the same DTC is recorded Reading and Clearing Diagnostic Trouble Codes.
