*NO RESPONSE FROM SAS (STEERING ANGLE SENSOR)





For a complete wiring diagram Consult Diagrams/Electrical.





Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION
Turn the ignition on.

NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.

With the scan tool, select ECU view.

NOTE: A red X will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.

Does the scan tool display a red X next to the module?

Yes

- Go To 2

No

- The no response condition is not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness connectors for broken, bent, pushed out, and corroded terminals.

2. (F941) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN OR SHORTED




Turn the ignition off.
Disconnect the Steering Angle Sensor harness connector.
Using a 12-volt test light connected to ground, check the (F941) Fused Ignition Switch Output (Run-Start) circuit at the Steering Angle Sensor harness connector.
Does the test light illuminate brightly?

Yes

- Go To 3

No

- Repair the ((F941) Fused Ignition Switch Output (Run-Start) circuit for an open or short.
- Perform the BODY VERIFICATION TEST - VER 1.Body Verification Test.

3. (Z907) GROUND CIRCUIT OPEN




Using a 12-volt test light connected to 12-volts, check the (Z907) ground circuit Steering Angle Sensor harness connector.
Does the test light illuminate brightly?

Yes

- Go To 4

No

- Repair the (Z907) ground circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1.Body Verification Test.

4. (D65) CAN C BUS (+) CIRCUIT OPEN
Turn the ignition off.
Disconnect the FCM C1 harness connector.
Measure the resistance of the (D65) CAN C Bus (+) circuit between the FCM connector and the Steering Angle Sensor connector.
Is resistance below 5.0 ohms?

Yes

- Go To 5

No

- Repair the (D65) CAN C Bus (+) circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1.Body Verification Test.

5. (D64) CAN C BUS (-) CIRCUIT OPEN
Measure the resistance of the (D64) CAN C Bus (-) circuit between the FCM connector and the Steering Angle Sensor connector.
Is resistance below 5.0 ohms?

Yes

- Replace the Steering Angle Sensor.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Repair the (D64) CAN C Bus (-) circuit for an open.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test.
