2010 Cadillac CTS Sedan AWD V6-3.6L Page 552
Conditions for Running the DTC
* CTD System is armed
* Intrusion sensor is enabled
Conditions for Setting the DTC
The BCM does not receive the power-up acknowledgement from the intrusion sensor
Action Taken When the DTC Sets
The BCM will ignore all inputs from the intrusion sensor for the remainder of the CTD System arming cycle
Conditions for Clearing the DTC
A current DTC will clear when the RIM receives a power-up acknowledgement from the intrusion sensor during the next CTD system arming cycle

Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the intrusion sensor.
2. Ignition ON, verify a test lamp illuminates between the B+ circuit terminal A and ground.
瀚慖f the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
3. Ignition OFF, disconnect the X7 harness connector at the BCM.
4. Ignition ON, test for less than 1 volt between the following signal circuit terminals and ground:
* Terminal 12
* Terminal 15
瀚慖f greater than the specified range, test the signal circuit for a short to ground.
5. Test for infinite resistance between the following signal circuit terminals and ground:
* Terminal 12
* Terminal 15
瀚慖f less than the specified value, test the signal circuit for a short to ground.
6. Test for less than 2 ohms of resistance between the following signal circuit terminals:
* Terminal 12 at the BCM and terminal B at the intrusion sensor
* Terminal 15 at the BCM and terminal C at the intrusion sensor
瀚慖f greater than the specified range, test the signal circuit for an open/high resistance.
