WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Fail Case 1
- No IMS direction switch DTCs are set.
- A valid IMS direction indicated by the IMS switch does not match the direction indicated by the HPCM software 6 out of 8 times within 200 milliseconds.
Fail Case 2
- No IMS direction switch DTCs are set.
- Two valid IMS directions are indicated at the same time 6 out of 8 times within 200 milliseconds.
Fail Case 3
- One IMS direction switch circuit has failed.
- The HPCM calculates a transmission direction based upon the remaining IMS circuits but it does not match the direction indicated by the HPCM software 6 out of 8 times within 200 milliseconds.
Fail Case 4
- Multiple IMS directions and one IMS direction switch circuit has failed.
- Based upon the remaining IMS circuits the HPCM calculated two directions at the same time.
Fail Case 5
- More than one IMS direction circuit has failed and the HPCM cannot calculate a transmission direction.
- Ignition voltage is 9.5-18V.
