Cycle Outputs

Use a scan tool in order to cycle the Body Control Module (BCM) output functions.
1. Connect a scan tool to the Data Link Connector (DLC).
2. The first menu on the scan tool will be the MAIN MENU.
3. Input vehicle information as requested by the scan tool.
4. Select the BODY CONTROL MODULE in the APPLICATIONS MENU. This will take the scan tool to the BODY CONTROL MODULE MAIN MENU.
5. Select the SPECIAL FUNCTIONS feature. This will take the scan tool to the SPECIAL FUNCTIONS MAIN MENU.
6. Select the OUTPUT CONTROL feature.

When the BCM output cycling is selected. the BCM commands the output cycling. This feature can be used to determine if the BCM is able to cycle an output regardless of the inputs or any specific program instructions. Once a test is selected, the scan tool will command the BCM to energize the selected output. The scan tool then displays the status of the selected output. The displayed information represents only what was BCM-commanded, not what action was actually taken. Check if the BCM is performing each of the selected output functions.
