DTC C1297: Steering Angle Sensor: Procedure

1. Clear the DTC. Refer to DTC CHECK / CLEAR .
2. Turn the engine switch off.
3. Turn the engine switch on (IG) again and check that no CAN communication system DTC(s) is output. Refer to DIAGNOSIS SYSTEM .
4. Start the engine.
5. Drive the vehicle and turn the steering wheel to the right and left at a speed of 35 km/h (24 mph) and check that no brake control system (steering angle sensor) DTC (C1432, C1433 or C1434) is output. Refer to DIAGNOSTIC TROUBLE CODE CHART .

   Result

   Result		Proceed to
   Neither CAN communication system DTC nor brake control system DTC is output		A
   CAN communication system DTC is output		B
   Brake control system (steering angle sensor) DTC (C1432, C1433 or C1434) is output		C

   HINT: 

   When DTCs indicating a CAN communication system malfunction are output, repair the CAN communication system before repairing each corresponding sensor.
