3 | Does the odometer operate properly? | -- | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 11 |
4 |
Does the Vehicle Speed Sensor parameter match the speedometer display? | -- | Go to Step 7 | Go to Step 5 |
5 |
Does the voltage measure greater than the specified value? | 9 V | Go to Step 9 | Go to Step 6 |
6 | Test the vehicle speed signal circuit for an open or for a high resistance between the instrument panel cluster (IPC) and the PCM. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 13 | Go to Step 8 |
7 | Inspect for poor connections at the harness connector of the DIC. 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 13 | Go to Step 10 |
8 | Inspect for poor connections at the harness connector of 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 13 | Go to Step 11 |
9 | Inspect for poor connections at the harness connector of 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 13 | Go to Step 12 |
10 | Replace the DIC. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement? | -- | Go to Step 13 | -- |
11 | Replace the IPC. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement? | -- | Go to Step 13 | -- |
12 | Replace the PCM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement? | -- | Go to Step 13 | -- |
13 | Operate the system in order to verify the repair. Did you correct the condition? | -- | System OK | Go to Step 2 |
