1 | Did you perform the Lighting Systems Diagnostic System Check? | Go to Step 2 | |||||||||||||||||||
2 | Verify that the turn signal lamps and/or indicators are inoperative. Do the turn signal lamps and/or indicators operate normally? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 | ||||||||||||||||||
3 | Are only the turn signal indicators in the instrument panel cluster (IPC) inoperative? | Go to Step 4 | Go to Step 5 | ||||||||||||||||||
4 | Test the inoperative turn signal supply voltage circuit to the IP cluster 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 18 | Go to Step 11 | ||||||||||||||||||
5 | Is only 1 turn signal lamp inoperative? | Go to Step 6 | Go to Step 7 | ||||||||||||||||||
6 | Test for an open, high resistance, or short to ground in the turn signal lamp supply voltage circuit or an open or high resistance in the turn signal lamp ground circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 18 | Go to Step 15 | ||||||||||||||||||
7 | Inspect the IGN E fuse and the FLASHER fuse in the underhood fuse block. Is either fuse open? | Go to Step 10 | Go to Step 8 | ||||||||||||||||||
8 | Test for an open or high resistance in the following circuits. Refer to Circuit Testing and Wiring Repairs in Wiring Systems:
Did you find and correct the condition? | Go to Step 18 | Go to Step 9 | ||||||||||||||||||

Is continuity present? | Go to Step 10 | Go to Step 12 | ||||||||||||||||||
10 | Test the following circuits for an open, high resistance or short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems:
Did you find and correct the condition? | Go to Step 18 | Go to Step 13 | ||||||||||||||||||
11 | Inspect for poor connections at the IPC. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 18 | Go to Step 14 | ||||||||||||||||||
12 | Inspect for poor connections at the multifunction turn signal switch. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 18 | Go to Step 16 | ||||||||||||||||||
13 | Inspect for poor connections at the turn/hazard flasher. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 18 | Go to Step 17 | ||||||||||||||||||

Important: Perform the set up procedure for the IPC. Replace the IPC. Refer to Instrument Cluster Replacement in Instrument Panel, Gages, and Console. Did you complete the repair? | Go to Step 18 | -- | ||||||||||||||||||
15 | Replace or repair the inoperative bulb/socket. Did you complete the repair? | Go to Step 18 | -- | ||||||||||||||||||
16 | Replace the multifunction turn signal switch. Refer to Turn Signal Multifunction Switch Replacement in Steering Wheel and Column. Did you complete the repair? | Go to Step 18 | -- | ||||||||||||||||||
17 | Replace the hazard/turn flasher. Refer to Hazard and Turn Signal Flasher Replacement . Did you complete the repair? | Go to Step 18 | -- | ||||||||||||||||||
18 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 3 | ||||||||||||||||||
