1 | Did you perform the Lighting System Diagnostic System Check? | Go to Step 2 | |
2 |
Do the daytime running lamps remain illuminated? | Go to Step 3 | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems |
3 | With a scan tool, observe the Daytime Running Lamp parameter in the Dash Integration Module (DIM) outputs data list. Does the scan tool indicate that the Daytime Running Lamp parameter is OFF? | Go to Step 4 | Go to Step 8 |
4 |
Did the DRL headlamps turn OFF? | Go to Step 5 | Go to Step 9 |
5 | Connect a test lamp between the control circuit of the DRL relay to the battery positive voltage circuit of the DRL relay coil. Does the test lamp illuminate? | Go to Step 6 | Go to Step 7 |
6 | Test for a short to ground in the DRL relay control circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 12 | Go to Step 8 |
7 | Inspect for poor connections at the DRL relay. 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 12 | |
8 | Inspect for poor connections at the Dash Integration Module (DIM). 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 12 | Go to Step 11 |
9 | Repair the short to voltage in the DRL supply voltage circuit. Refer to Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 12 | -- |
10 | Replace the DRL relay. Refer to Relay Replacement in Wiring Systems. Did you complete the replacement? | Go to Step 12 | -- |
11 |
Important:: Perform the setup procedure for the Dash Integration Module (DIM). Refer to Body Control Module (BCM) Programming/RPO Configuration . Replace the DIM. Refer to Dash Integration Module Replacement in Body Controls. Did you complete the replacement? | Go to Step 12 | -- |
12 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 2 |
