1 | Did you review the Exterior Lighting Systems Description and Operation and perform the necessary inspections? | -- | Go to Step 2 | |
2 | Verify that the hazard lamps are inoperative. Do the hazard lamps operate normally? | -- | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 | Inspect the HAZARD LPS fuse in the IP Fuse Block. Is the fuse open? | -- | Go to Step 4 | Go to Step 5 |
4 | Using a J 39200 Digital Multimeter (DMM), Disconnect the hazard warning switch and test for a short to ground in the hazard warning switch battery positive voltage supply circuit. Refer to Circuit Testing in Wiring Systems. Was a short to ground found? | -- | Go to Step 8 | Go to Step 12 |
5 | Using a test lamp to ground, test the battery positive voltage supply circuit at the hazard warning switch connector. Refer to Circuit Testing in Wiring Systems. Does the test lamp illuminate? | -- | Go to Step 6 | Go to Step 9 |
6 | Connect the test lamp between the battery positive voltage supply circuit and the ground circuit at the hazard warning switch connector. Refer to Circuit Testing in Wiring Systems. Does the test lamp illuminate? | -- | Go to Step 7 | Go to Step 10 |
7 |
Does the test lamp flash? | B+ | Go to Step 11 | Go to Step 12 |
8 | Repair the short to ground in the hazard warning switch battery positive voltage supply circuit. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | -- | Go to Step 13 | -- |
9 | Repair the open or high resistance in the hazard warning switch battery positive voltage supply circuit. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | -- | Go to Step 13 | -- |
10 | Repair the open or high resistance in the ground circuit to the hazard warning switch. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | -- | Go to Step 13 | -- |
11 | Repair the open or high resistance in the front turn signal switch signal circuits. Refer to Wiring Repairs in Wiring Systems. Is the repair complete? | -- | Go to Step 13 | -- |
12 | Replace the hazard warning switch. Refer to Hazard Warning Switch Replacement . Is the repair complete? | -- | Go to Step 13 | -- |
13 | Operate the system in order to verify the repair. Did you correct the condition? | -- | System OK | Go to Step 3 |
