Circuit/System Testing
WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition OFF, disconnect the harness connectors of the K84 keyless entry control module.
- Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 10 Ω between the ground circuit terminals listed below and ground:
- Terminal 2 X2
- Terminal 6 X2
- If greater than the specified range, test the ground circuit for an open/high resistance.
- Test for greater than 9 V between the B+ circuit terminals listed below and ground:
- Terminal 1 X2
- Terminal 5 X2
- If less than the specified range, test the B+ circuit for a short to ground or an open/high resistance.
- If the circuits test normal, replace the K84 keyless entry control module.
