WARNING: This page is about a different car, the 2008 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connector at the TCM X1 connector.
- Ignition ON, install a 3A fused jumper wire between the TCM X1 connector terminal 5 and ground. Verify the scan tool ECM PNP switch parameter displays Park/Neutral.
- If not the specified value, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the ECM.
- If all circuits test normal, replace the TCM/Tr Switch.
