1 | Did you review the Exterior Lighting Systems Description and Operation and perform the necessary inspections? | Go to Step 2 | |
2 | Verify that the turn signal lamps and/or indicators are always ON or flashing. Do the turn signal lamps 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) always ON or flashing? | Go to Step 9 | Go to Step 4 |
4 | Is only one turn signal lamp or the turn signal lamps on one side of the vehicle always ON or flashing? | Go to Step 5 | Go to Step 6 |
5 | Inspect the affected bulb/socket for an internal short, poor terminal contact, or a shorted filament. Was a problem found? | Go to Step 10 | Go to Step 6 |
6 | Disconnect the turn signal lamp flasher. Do the turn signals and indicators still illuminate with the multifunction turn signal switch in any position? | Go to Step 7 | Go to Step 12 |
7 | Test the turn signal lamp supply voltage and turn signal switch signal circuits for a short to voltage. Refer to Circuit Testing in Wiring Systems. Was a problem found? | Go to Step 8 | Go to Step 11 |
8 | Repair the short to voltage in the turn signal lamp supply voltage circuit or the turn signal switch signal circuit. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | Go to Step 13 | -- |
9 | Replace the IPC. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the repair? | Go to Step 13 | -- |
10 | Replace or repair the affected bulb/socket. Did you complete the repair? | Go to Step 13 | -- |
11 | Replace the multifunction switch. Refer to Turn Signal Multifunction Switch Replacement in Steering Wheel and Column. Did you complete the repair? | Go to Step 13 | -- |
12 | Replace the turn signal lamp flasher. Refer to Hazard and Turn Signal Flasher Replacement . Did you complete the repair? | 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 |
