1 | Did you review the Lighting System Description and Operation and perform the necessary inspections? | Go to Step 2 | |
2 | Verify that the tail lamps are inoperative. Does the system operate normally? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 |
Does the test lamp illuminate? | Go to Step 4 | Go to Step 5 |
4 | Use a test lamp to check junction block 1, C6 cavity 9 to ground. Does the test lamp illuminate? | Go to Step 6 | Go to Step 7 |
5 | Connect a test lamp between cavity 3 of the TAIL relay and ground. Do the park and tail lamps illuminate? | Go to Step 9 | Go to Step 8 |
6 | Repair the open in the GRN wire between the junction block 1, C6 cavity 9 and the junction block 2, C3 cavity 9. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | Go to Step 14 | -- |
7 | Replace junction block 1. Is the replacement complete? | Go to Step 14 | -- |
8 |
Replace the TAIL Relay. Is the replacement complete? | Go to Step 14 | -- |
9 | Test for high resistance between cavity 6 of connector C3 of junction block 2 and cavity 16 of the DRL control module connector. Is there high resistance in the LT GRN wire? | Go to Step 10 | Go to Step 11 |
10 | Test for an open between cavity 14 of the turn/signal/headlamp switch connector and cavity 17 of the DRL control module connector. Is an open condition present? | Go to Step 13 | Go to Step 12 |
11 | Repair the open in the LT GRN wire between cavity 6 of connector C3 of junction block 2 and cavity 16 of the DRL control module connector . Refer to Wiring Repairs in Wiring Systems. Is the replacement complete? | Go to Step 14 | -- |
12 | Repair the open in the LT GRN/BLK wire between cavity 17 of the DRL control module connector and cavity 14 of the turn signal/headlamp switch. Refer to Wiring Repairs in Wiring Systems. Is the replacement complete? | Go to Step 14 | -- |
13 | Replace the DRL module. Refer to Daytime Running Lights (DRL) Control Module Replacement . Is the replacement complete? | Go to Step 14 | -- |
14 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 3 |
