1 | Did you perform the Instrument Cluster Diagnostic Starting Point? | Go to Step 2 | Go to |
2 |
Does the Engine Speed parameter match the tachometer display? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 | Using a multimeter, Inspect the Instrument Panel cluster Engine Speed Output circuit cavity 27 for 6.5v-7.0v. Refer to Testing for Intermittent Conditions and Poor Connections in wiring systems Is voltage within specified value? | Go to Step 6 | Go to Step 4 |
4 | Using a multimeter, Inspect the PCM Engine Speed Output circuit connector 4 cavity 5 (C3 cavity 3 LNK) for 6.5v-7.0v. Refer to Testing for Intermittent Conditions and Poor Connections in wiring systems Is voltage within specified value? | Go to Step 5 | Go to Step 7 |
5 | Repair the open or high resistance in the Engine Speed Output circuit between PCM and the I/P. Refer to Wiring Repairs in Wiring Systems Did you complete the repair? | Go to Step 8 | -- |
6 | Replace the IPC. Refer to Instrument Cluster Replacement . Did you complete the replacement? | Go to Step 8 | -- |
7 | Replace the PCM. Refer to Powertrain Control Module Replacement . Did you complete the replacement? | Go to Step 8 | -- |
8 | Operate the system in order to verify the repair. Did you correct the condition? | System OK | Go to Step 2 |
