Diagnostic Test

1. TEST FOR INTERMITTENT CONDITION

NOTE: Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.


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 sensor?

Yes


No

2. (F943) FUSED RUN/START RELAY OUTPUT CIRCUIT OPEN OR SHORTED



Turn the ignition off.
Disconnect the Steering Angle Sensor harness connector.
Turn the ignition on.
Using a 12-volt test light connected to ground, check the (F943) Fused Run/Start Relay Output circuit.

Does the test light illuminate brightly?

Yes


No

3. (Z910) GROUND CIRCUIT OPEN



Turn the ignition off.
Using a 12-volt test light connected to 12-volts, check the (Z910) ground circuit.

Does the test light illuminate brightly?

Yes


No

4. (D65) CAN C BUS (+) CIRCUIT OPEN



Disconnect the TIPM C1 harness connector.
Measure the resistance of the (D65) CAN C Bus (+) circuit between the TIPM C1 harness connector and the Steering Angle Sensor connector.

Is resistance below 5.0 ohms?

Yes


No

5. (D64) CAN C BUS (-) CIRCUIT OPEN



Measure the resistance of the (D64) CAN C Bus (-) circuit between the TIPM C1 harness connector and the Steering Angle Sensor connector.

Is resistance below 5.0 ohms?

Yes


No
