DTC

U0422:00/U0422:28/U0422:64/U0422:86

Steering angle sensor

DETECTION CONDITION

•  U0422:00/U0422:86

―  The steering angle sensor detects signal modulation or steering angle that exceeds specification.

•  U0422:28

―  The neutral position of the steering angle cannot be estimated from the signals from the ABS wheel-speed sensors and the SAS control module.

•  U0422:64

―  The signal from the steering angle sensor remains unchanged when the steering angle is turned to the right and left.

POSSIBLE CAUSE

•  Improper installation or positioning of the steering angle sensor

•  Signal error from the ABS wheel-speed sensor

•  Signal error from the SAS control module

•  Signal errors from sensors due to rough road driving

•  Steering angle sensor malfunction

•  Poor connection at connectors (female terminal)

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT FOR BCM MALFUNCTION • Switch the ignition to off. • Using the M-MDS, perform the DTC inspection for the BCM. (See DTC INSPECTION [BCM].) • Is the DTC displayed?	Yes	Go to applicable DTC inspection. (See DTC TABLE [BCM].)
1		No	Go to the next step.
2	VERIFY THAT THE SAME DTC IS NOT PRESENT • Clear the DTCs from the memory. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Start the engine and drive the vehicle at 10 km/h {6.2 mph} or more. • Are the same DTCs present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION.)
2		No	Go to the next step.
3	VERIFY THAT NO OTHER DTCS ARE PRESENT • Are any other DTCs output?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
3		No	DTC troubleshooting completed.
