Circuit/System Testing (Non-Hybrid)
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.
- Ignition OFF, disconnect the PNP switch harness connector.
- Ignition ON, verify the scan tool TR. Sw. A/B/C/P parameter is HI/HI/HI/HI.
- If not the specified value, test each signal circuit for a short to ground. If all circuits test normal, replace the TCM.
- Ignition OFF, test for less than 10 ohms between terminal 11 on the harness side and ground.
- If greater than the specified value, check the ground circuit for an Open/High resistance.
- If all circuits test normal, test or replace the PNP Switch.
