Circuit/System Testing
- Verify that DTC C0186 or C0196 is not set
- Ignition OFF, disconnect the harness connector at the EBCM.
- Ignition ON, test for less than 1 volt between the circuit terminal of the appropriate circuit and ground.
- Reference voltage circuit terminal 5
- Reference ground circuit terminal 40
- Serial Data circuit terminals 18 and 19
- If greater than the specified range, test the appropriate circuit for a short to voltage.
- Ignition OFF, test for infinite resistance between the ignition voltage terminal of the appropriate sensor listed below and ground.
- Reference voltage circuit terminal 5
- Reference ground circuit terminal 40
- Serial Data circuit terminals 18 and 19
- If less than the specified value, test the appropriate circuit for a short to ground.
- Ignition OFF, disconnect the harness connector at the Steering Angle Sensor.
- Ignition OFF, test for less than 2 ohms between the appropriate circuit terminals listed below.
- Reference voltage circuit terminal 5 at the EBCM harness connector and terminal 1 at the Steering Angle Sensor harness connector.
- Reference ground circuit terminal 40 at the EBCM harness connector and terminal 6 at the Steering Angle Sensor harness connector.
- Communication circuit terminal 18 at the EBCM harness connector and terminal 3 at the Steering Angle Sensor harness connector.
- Communication circuit terminal 19 at the EBCM harness connector and terminal 4 at the Steering Angle Sensor harness connector.
- If greater than the specified value, test the ignition voltage circuit for an open or high resistance.
- If all circuits test normal, replace the Steering Angle Sensor. If the DTC resets replace the EBCM.
