1 | Did you perform the Lighting Systems Diagnostic System Check? | -- | Go to Step 2 | |
2 |
Do the left turn signal lamps operate properly? | -- | Go to Step 3 | |
3 | With a scan tool, observe the Left Turn Signal data parameter in the instrument cluster (IPC) inputs data list. Does the scan tool indicate that the Left Turn Signal data parameter turns ON and OFF? | -- | Go to Step 6 | Go to Step 4 |
4 | Test the left turn signal lamp supply voltage circuit of the Instrument Cluster (IPC) 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 7 | Go to Step 5 |
5 | Inspect for poor connections at the harness connector of the Instrument Cluster (IPC). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 7 | Go to Step 6 |
6 | Replace the Instrument Cluster (IPC). Refer to Instrument Cluster Replacement in Instrument Panel, Gauges, and Console. Did you complete the replacement? | -- | Go to Step 7 | -- |
7 | Operate the system in order to verify the repair. Did you correct the condition? | -- | System OK | Go to Step 2 |
