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 | ||||||||||||||||
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. 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 Control Module References. 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 | ||||||||||||||||
