PINPOINT TEST G307559p6: C1277, C1295; STEERING ANGLE SENSOR (SA SENSOR) 'A' AND 'B' CIRCUIT FAILURE

G307559t20: CHECK THE VOLTAGE SUPPLY TO THE STEERING ANGLE SENSOR
1. Disconnect the steering angle sensor electrical connector IP37.
2. Turn the ignition switch to the ON position.
3. Measure the voltage between IP37, pin 04 (R) and GROUND.

^ Is the voltage less than 10 volts?

-> Yes GO to Pinpoint Test G307559t21.

-> No GO to Pinpoint Test G307559t22.

G307559t21: CHECK THE STEERING ANGLE SENSOR VOLTAGE SUPPLY CIRCUIT FOR HIGH RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the ABS/DSC module electrical connector EC30.
3. Measure the continuity between EC30, pin 07 (R) and IP37, pin 04 (R).

^ Is the resistance greater than 5 ohms?

-> Yes REPAIR the high resistance circuit. This circuit includes the splice IPS14. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

-> No Contact dealer technical support for advice on possible ABS/DSC module failure.

G307559t22: CHECK THE STEERING ANGLE SENSOR GROUND SUPPLY CIRCUIT
1. Turn the ignition switch to the OFF position.
2. Reconnect the ABS/DSC module electrical connector EC30.
3. Disconnect the yaw/lateral rate sensor electrical connector IP23.
4. Turn the ignition switch to the ON position.
5. Measure the resistance between IP37, pin 01 (B) and GROUND.

^ Is the resistance greater than 5 ohms?

-> Yes REPAIR the high resistance circuit. This circuit includes the splice IPS10. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

-> No GO to Pinpoint Test G307559t23.

G307559t23: CHECK THE STEERING ANGLE SENSOR SIGNAL CIRCUIT 'A' FOR HIGH RESISTANCE
1. Turn the ignition switch to the OFF position.
2. Disconnect the ABS/DSC module electrical connector EC30.
3. Measure the resistance between EC30, pin 03 (Y) and IP37 pin 02 (Y).

^ Is the resistance greater than 5 ohms?

-> Yes GO to Pinpoint Test G307559t24.

-> No REPAIR the high resistance circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

G307559t24: CHECK THE STEERING ANGLE SENSOR SIGNAL CIRCUIT 'B' FOR HIGH RESISTANCE
1. Measure the resistance between EC30, pin 06 (U) and IP37, pin 03 (U).

^ Is the resistance greater than 5 ohms?

-> Yes GO to Pinpoint Test G307559t25.

-> No REPAIR the high resistance circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

G307559t25: CHECK THE STEERING ANGLE SENSOR SIGNAL CIRCUIT 'A' FOR SHORT TO GROUND
1. Measure the resistance between IP37, pin 02 (Y) and GROUND.

^ Is the resistance less than 10,000 ohms?

-> Yes REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

-> No GO to Pinpoint Test G307559t26.

G307559t26: CHECK THE STEERING ANGLE SENSOR SIGNAL CIRCUIT 'B' FOR SHORT TO GROUND
1. Measure the resistance between IP37, pin 03 (B) and GROUND.

^ Is the resistance less than 10,000 ohms?

-> Yes REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

-> No GO to Pinpoint Test G307559t27.

G307559t27: CHECK THE STEERING ANGLE SENSOR SIGNAL CIRCUITS 'A' AND 'B' FOR SHORT TO EACH OTHER
1. Measure the resistance between IP37, pin 03 (B) IP37, pin 02 (Y).

^ Is the resistance less than 5 ohms?

-> Yes REPAIR the short circuit. For additional information, refer to Vehicle/Diagrams. CLEAR the DTC. TEST the system for normal operation.

-> No INSTALL a new steering angle sensor. CLEAR the DTC. TEST the system for normal operation. If the DTC is repeated, contact dealer technical support for advice on possible ABS/DSC module failure.
