1 | Did you perform the Lighting Diagnostic System Check? | Go to Step 2 | |
2 | Turn ON each of the dome fluorescent work lamps. Does the system operate normally? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 | Are all of the dome fluorescent work lamps inoperative? | Go to Step 5 | Go to Step 4 |
4 | Test the dome fluorescent work lamp signal and ground circuits for a high resistance, or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 21 | Go to Step 12 |
5 | Inspect the dome fluorescent work lamps fuse. Is the fuse open? | Go to Step 15 | Go to Step 6 |
6 | Connect a test lamp between the battery positive voltage circuit of the dome fluorescent work lamp relay, coil side and a good ground, and between the battery positive voltage circuit of the dome fluorescent work lamp relay, switch side and a good ground. Does the test lamp illuminate in both positions? | Go to Step 7 | Go to Step 14 |
7 | Test for a ground signal at the dome fluorescent work lamps relay control circuit of the dome fluorescent work lamp relay. Is a ground signal present? | Go to Step 10 | Go to Step 8 |
8 | Test for a ground signal at the dome fluorescent work lamp signal circuit of body control module (BCM). Is a ground signal present? | Go to Step 9 | Go to Step 13 |
9 | Test the dome fluorescent work lamp relay control circuit for a high resistance, or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 21 | Go to Step 13 |
10 | Connect a 3 amp fused jumper between the battery positive voltage circuit and the dome fluorescent work lamp signal circuit of the dome fluorescent work lamp relay. Do the lamps illuminate? | Go to Step 11 | Go to Step 16 |
11 | Inspect for poor connections at the harness connector of the dome fluorescent work lamp 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 21 | Go to Step 17 |
12 | Inspect the inoperative bulb for an open filament. Is the bulb OK? | Go to Step 19 | Go to Step 18 |
13 | 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 21 | Go to Step 20 |
14 | Repair the battery positive voltage circuit of the dome fluorescent work lamp relay. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 21 | -- |
15 | Repair the dome fluorescent work lamp signal or the battery positive voltage circuit of the dome fluorescent work lamp relay. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 21 | -- |
16 | Repair the dome fluorescent work lamp signal circuit. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 21 | -- |
17 | Replace the dome fluorescent lamps relay. Refer to Relay Replacement In Wiring Systems. Did you complete the replacement? | Go to Step 21 | -- |
18 | Replace the inoperative bulb. Did you complete the replacement? | Go to Step 21 | -- |
19 | Replace the dome fluorescent work lamp. Did you complete the replacement? | Go to Step 21 | -- |
20 |
Important: Perform the setup procedure for the BCM. Replace the body control module (BCM). Refer to Body Control Module Replacement in Body Control System. Did you complete the replacement? | Go to Step 21 | -- |
21 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 3 |
