Circuit/System Testing
WARNING: This page is about a different car, the 2008 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition ON, verify DTC C0895 is set as current.
- If the DTC is not current, refer to Charging System Test .
- Ignition OFF, disconnect the harness connector at the ESC module.
- Ignition OFF, test for less than 5 ohms between the ground circuit terminal 47 and ground.
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Engine running, test for 9.5-15.5 volts between the B+ circuit terminal 32 and ground.
- If greater than the specified range, refer to Charging System Test .
- If less than the specified range, test the B+ circuit for a short to ground or an open/high resistance.
- If all circuits test normal, replace the ESC module.
