1 | Did you perform the Diagnostic System Check - Vehicle? | 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 | 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 IPC for an open or high resistance. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 21 | Go to Step 13 | ||||||||||||||||
5 | Is only one turn signal lamp inoperative? | Go to Step 6 | Go to Step 8 | ||||||||||||||||
6 | Inspect the inoperative bulb/socket for an internal short, poor terminal contact, or an open filament. Was a problem found? | Go to Step 18 | Go to Step 7 | ||||||||||||||||
7 | Test for an open, high resistance, or short to ground in the turn signal lamp supply voltage circuit. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 21 | Go to Step 16 | ||||||||||||||||
8 | Inspect the IGN E fuse and the FLASHER fuse. Is either fuse open? | Go to Step 11 | Go to Step 9 | ||||||||||||||||
9 | Test for an open or high resistance in the following circuits:
Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 21 | Go to Step 10 | ||||||||||||||||

Is continuity present? | Go to Step 12 | Go to Step 14 | ||||||||||||||||
11 | Test the following circuits for a short to ground:
Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 21 | Go to Step 14 | ||||||||||||||||
12 | Test the following circuits for an open or high resistance:
Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? | Go to Step 21 | Go to Step 15 | ||||||||||||||||
13 | Inspect for poor connections at the IPC. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition? | Go to Step 21 | Go to Step 17 | ||||||||||||||||
14 | Inspect for poor connections at the multifunction turn signal switch. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition? | Go to Step 21 | Go to Step 19 | ||||||||||||||||
15 | Inspect for poor connections at the turn signal/hazard flasher module. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition? | Go to Step 21 | Go to Step 20 | ||||||||||||||||
16 | Repair the ground circuit of the inoperative lamp. Refer to Wiring Repairs . Did you complete the repair? | Go to Step 21 | -- | ||||||||||||||||
17 | Replace the IPC. Refer to Control Module References for replacement, setup, and programming. Did you complete the repair? | Go to Step 21 | -- | ||||||||||||||||
18 | Replace or repair the inoperative bulb/socket. Did you complete the repair? | Go to Step 21 | -- | ||||||||||||||||
19 | Replace the multifunction turn signal switch. Refer to Turn Signal Multifunction Switch Replacement . Did you complete the repair? | Go to Step 21 | -- | ||||||||||||||||
20 | Replace the turn signal/hazard flasher module. Refer to Hazard and Turn Signal Flasher Replacement . Did you complete the repair? | 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 | ||||||||||||||||
