Circuit Description
The security indicator is used by both the VTD system and the CTD system. The security indicator is controlled by the body control module (BCM) via the security indicator control circuit. When VTD or CTD requests the security indicator be illuminated, the BCM grounds the security indicator control circuit, illuminating the security indicator.
Conditions for Setting the DTC
The BCM detects a short to battery in the security indicator control circuit.
Action Taken When the DTC Sets
The BCM will set and store DTC B0688
Conditions for Clearing the MIL/DTC
| • | The BCM no longer detects a short to battery in the security indicator control circuit. |
| • | A scan tool is used to clear the DTC. |
Step | Action | Yes | No |

Does the security indicator turn ON and OFF with each command? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 | Test for a short to battery in the security indicator control circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 6 | Go to Step 4 |
4 | Inspect for poor connections at the harness connector of the BCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 6 | Go to Step 5 |

Important: The BCM programming and setup procedure must be performanced when replacing the BCM. Refer to Body Control Module (BCM) Programming/RPO Configuration in Body Control System. Replace the BCM. Refer to Body Control Module Replacement in Body Control System. Did you complete the replacement? | Go to Step 6 | -- |
6 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 1 |
