Circuit/System Verification

Arm the content theft deterrent system. The security LED should illuminate and/or flash during the arming sequence.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the B10B Ambient Light/Sunload Sensor.

2. Test for less than 10 ohm between the low reference circuit terminal 6 and ground.

瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance.

3. Ignition ON, test for less than 1 V between the control circuit terminal 1 and ground.

瀚慖f greater than the specified range, test the control circuit for a short to voltage. If the circuit tests normal, replace the K9 BCM.

4. Command the security LED ON. Test for B+ between the control circuit terminal 1 and ground.

瀚慖f less than the specified range, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace

the K9 BCM.

5. If all circuits test normal, replace the B10B Ambient Light/Sunload Sensor.
