1 | Did you perform the Instrument Cluster Diagnostic System Check? | -- | Go to Step 2 | |
2 | Is the PRNDL display and the DIC display inoperative? | -- | Go to Step 9 | Go to Step 3 |
3 |
Does the Engine Speed parameter match the tachometer display? | -- | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 4 |
4 |
Is the voltage measured greater than the specified value? | 9.0 V | Go to Step 5 | Go to Step 6 |
5 | Test the engine speed signal circuit for a short to battery voltage between the IPC and the PCM. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 12 | Go to Step 8 |
6 | Test the engine speed signal circuit for an open, a short to ground, or high resistance between the IPC and the PCM. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 12 | Go to Step 7 |
7 | Inspect for poor connections at the 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 12 | Go to Step 10 |
8 | Inspect for poor connections at the PCM. 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 12 | Go to Step 11 |
9 | Repair the open in the Off/Run/Crank voltage circuit. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair? | -- | Go to Step 12 | -- |
10 | Replace the IPC. Refer to Instrument Cluster Replacement . Did you complete the replacement? | -- | Go to Step 12 | -- |
11 |
Important: Program the replacement PCM. Replace the PCM. Refer to Powertrain Control Module Replacement . Did you complete the replacement? | -- | Go to Step 12 | -- |
12 | Operate the system in order to verify the repair. Did you correct the condition? | -- | System OK | Go to Step 2 |
