C1290

DTC C1290 MALFUNCTION IN ZERO POINT OF STEERING SENSOR

CIRCUIT DESCRIPTION

DTC Detection Condition:

The steering angle sensor signal is sent to the skid control ECU through the CAN communication system. When there is a malfunction in the communication system, it will be detected by the diagnosis function.

INSPECTION PROCEDURE

NOTE: When replacing the master cylinder solenoid, perform zero point calibration.

HINT:
- When U0073/94, U0100/65, U0123/62, U0124/95 or U0126/63 is output together with C1231/31 and C1290/66, inspect and repair the trouble areas indicated by U0073/94, U0100/65, U0123/62, U0124/95 or U0126/63 first.
- When the speed sensor or the yaw rate and deceleration sensor has trouble, DTCs of the steering angle sensor may be output even when the steering angle sensor is normal. When DTCs of the speed` sensor (C0200/31, C0205/32, C0210/33, C0215/34, C1235/35, C1236/36, C1238/38, C1239/39) or yaw rate and deceleration sensor (C1232/32, C1234/34, C1243/43, C1244/44, C1245/45, C1381/97) are output together with other DTCs of the steering angle sensor, inspect and repair the speed sensor and yaw rate and deceleration sensor first, and then inspect and repair the steering angle sensor.
- Start the inspection from step 1 when using the hand-held tester and start from step 3 when not using the hand-held tester.

HINT:
- When troubleshooting in accordance with the DTC CHART, check DTCs before replacing the steering angle sensor.
- When troubleshooting in accordance with the PROBLEM SYMPTOMS TABLE, be sure to follow the table before replacing the steering angle sensor.
