1 | Did you perform the Diagnostic System Check - Vehicle? | Go to Step 2 | Go to Diagnostic System Check - Vehicle in Vehicle DTC Information |
2 |
Do the daytime running lamps (DRL) illuminate? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 |
Are the headlamps illuminated? | Go to Step 4 | Go to Step 5 |
4 | Connect a 15-amp fused jumper wire between the ground circuit of the DRL relay at the DRL resistor connector and the ground circuit at the DRL resistor connector. Are the headlamps illuminated? | Go to Step 7 | Go to Step 8 |
5 | Test the ground circuit of the DRL relay for an open or high resistance. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 11 | Go to Step 6 |
6 | 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 11 | Go to Step 9 |
7 | Inspect for poor connections at the harness connector of the DRL resistor. Refer to Underhood Electrical Center or Junction Block Replacement and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 11 | Go to Step 10 |
8 | Repair an open or high resistance in the ground circuit of the DRL resistor. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 11 | -- |
9 | Replace the DRL relay. Refer to Relay Replacement in Wiring Systems. Did you complete the replacement? | Go to Step 11 | -- |
10 | Replace the DRL resistor. Refer to Daytime Running Lamps (DRL) Resistor Replacement . Did you complete the replacement? | Go to Step 11 | -- |
11 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 2 |
