DETECTION CONDITION	C1295 • BCM detects the steering angle sensor internal abnormality (signal overflow). C1307 • BCM detects the steering angle sensor internal abnormality (signal jump). C1441, C1442, C144C • Open circuit in wiring harness between BCM and steering angle sensor C1443, C1444, C144A • Short to ground in wiring harness between BCM and steering angle sensor
POSSIBLE CAUSE	• Excessive grease is adhering to solid disc for steering angle detection • Steering wheel is off-center • Steering angle sensor connector or terminal malfunction • Open circuit in steering angle sensor power supply circuit • Open circuit in steering angle sensor ground circuit • BCM connector or terminal malfunction • Short to ground in steering angle sensor signal circuit • Short to power supply in steering angle sensor signal circuit • Open circuit in steering angle sensor signal circuit • Improper installation or positioning of steering angle sensor • Steering angle sensor malfunction • BCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT SOLID DISC FOR STEERING ANGLE DETECTION • Visually inspect the solid disc for the steering angle detection. • Is excessive grease adhering?	Yes	Wipe off excessive grease using a cloth, then go to Step 10.
1		No	Go to the next step.
2	INSPECT STEERING WHEEL FOR OFF-CENTER • Drive the vehicle and inspect the steering wheel position while driving in a straight line. • Is the steering wheel off-center?	Yes	Inspect and adjust the front wheel alignment to correct the steering wheel alignment, then go to Step 12. (See FRONT WHEEL ALIGNMENT.)
2		No	Go to the next step.
3	INSPECT STEERING ANGLE SENSOR CONNECTOR CONDITION • Turn the ignition switch to the LOCK position. • Disconnect the negative battery cable. • Disconnect the steering angle sensor connector. • Inspect the connector and terminals for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminal, then go to Step 12.
3		No	Go to the next step.
4	INSPECT STEERING ANGLE SENSOR POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT • Steering angle sensor connector is disconnected. • Reconnect the negative battery cable. • Turn the ignition switch to the ON position. • Measure the voltage at the steering angle sensor terminal F (wiring harness-side). • Is there any voltage?	Yes	Go to the next step.
4		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 12.
5	INSPECT STEERING ANGLE SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT • Steering angle sensor connector is disconnected. • Turn the ignition switch off. • Disconnect the negative battery cable. • Inspect for continuity between the steering angle sensor terminal B (wiring harness-side) and body ground. • Is there continuity?	Yes	Go to the next step.
5		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 12.
6	INSPECT BCM CONNECTOR CONDITION • Disconnect the BCM connector. • Inspect the connector and terminals for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminal, then go to Step 12.
6		No	Go to the next step.
7	INSPECT STEERING ANGLE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND • Steering angle sensor and BCM connectors are disconnected. • Inspect for continuity between the following terminals (wiring harness-side) and body ground: ― Steering angle sensor terminal A ― Steering angle sensor terminal C ― Steering angle sensor terminal E ― Steering angle sensor terminal D • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, then go to Step 12.
7		No	Go to the next step.
8	INSPECT STEERING ANGLE SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • Steering angle sensor and BCM connectors are disconnected. • Reconnect the negative battery cable. • Turn the ignition switch to the ON position. • Measure the voltage at the following terminals (wiring harness-side): ― Steering angle sensor terminal A ― Steering angle sensor terminal C ― Steering angle sensor terminal E ― Steering angle sensor terminal D • Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 12.
8		No	Go to the next step.
9	INSPECT STEERING ANGLE SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT • Steering angle sensor and BCM connectors are disconnected. • Turn the ignition switch to the LOCK position. • Disconnect the negative battery cable. • Inspect for continuity between the following terminals (wiring harness-side): ― Steering angle sensor terminal A—BCM terminal 3O ― Steering angle sensor terminal C—BCM terminal 3M ― Steering angle sensor terminal E—BCM terminal 3K ― Steering angle sensor terminal D—BCM terminal 3I • Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 12.
10	INSPECT FOR IMPROPER INSTALLATION OF STEERING ANGLE SENSOR • Visually inspect the installation of steering angle sensor. • Is there any malfunction?	Yes	Repair installation or replace the steering angle sensor, then go to Step 12. (See COMBINATION SWITCH REMOVAL/INSTALLATION.)
10		No	Go to the next step.
11	INSPECT STEERING ANGLE SENSOR • Inspect the steering angle sensor. (See STEERING ANGLE SENSOR INSPECTION.) • Is there any malfunction?	Yes	Replace the steering angle sensor, then go to the next step. (See COMBINATION SWITCH REMOVAL/INSTALLATION.)
11		No	Go to the next step.
12	VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the BCM using the M-MDS. (See CLEARING DTC [BCM].) • Start the engine and drive the vehicle at 10 km/h {6.2 mph} or more. • Perform the BCM DTC inspection using the M-MDS. (See DTC INSPECTION [BCM].) • Is the same DTC present?	Yes	Replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)
12		No	DTC troubleshooting completed.
