DTC C1210/36 Zero Point Calibration of Yaw Rate Sensor Undone; DTC C1336/39 Zero Point Calibration of Acceleration Sensor Undone: Description

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

The deceleration sensor is built into the yaw rate sensor.

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

These DTCs are also output when the calibration has not been completed.

DTC DETECTING CONDITIONS AND TROUBLE AREAS REFERENCE

DTC No.	DTC Detecting Conditions	Trouble Areas
C1210/36	When either of following 1 or 2 detected: When battery terminal connected, shift lever moved to non-P position (A/T) or parking brake OFF (M/T) within 15 seconds of ECU terminal IG1 initially turned ON. Yaw rate sensor zero point recorded in ECU deleted.	Yaw rate sensor and deceleration sensor Zero point calibration not complete PNP switch circuit (P position) (A/T) Parking brake switch circuit (M/T) Master cylinder solenoid (skid control ECU)
C1336/39	When either of following 1 or 2 detected: In TEST mode, shift lever shifted to non-P position (A/T) or parking brake OFF (M/T) 2 seconds after ECU terminal IG1 initially turned ON. Deceleration sensor zero point recorded in ECU deleted.	Yaw rate sensor and deceleration sensor Zero point calibration not complete PNP switch circuit (P position) (A/T) Parking brake switch circuit (M/T) Master cylinder solenoid (skid control ECU)
