Test Description
The numbers below refer to the step numbers on the diagnostic table.
-
This step tests for a malfunctioning cruise control module that is interrupting the vehicle speed signal circuit.
-
This step tests for a malfunctioning head-up display (HUD) that is interrupting the vehicle speed signal circuit.
-
This step tests for the proper voltage from the instrument panel cluster (IPC).

3 | Does the odometer operate properly? | -- | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 15 |
Does the Vehicle Speed Sensor parameter match the speedometer display? | -- | Go to Step 9 | Go to Step 5 | |
Does the Vehicle Speed Sensor parameter match the speedometer display? | -- | Go to Step 10 | Go to Step 6 | |
Does the voltage measure greater than the specified value? | 9 V | Go to Step 8 | Go to Step 7 | |
7 | Test the vehicle speed signal circuit for an open, a high resistance, or a short to ground. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 17 | Go to Step 11 |
8 | Test the vehicle speed signal circuit for a short to voltage. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | -- | Go to Step 17 | Go to Step 12 |
9 | Inspect for poor connections at the harness connector of the cruise control module. 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 17 | Go to Step 13 |
10 | Inspect for poor connections at the harness connector of the head-up display (HUD). 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 17 | Go to Step 14 |
11 | Inspect for poor connections at the harness connector of the instrument panel 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 17 | Go to Step 15 |
12 | 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 17 | Go to Step 16 |
13 | Replace the cruise control module. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement? | -- | Go to Step 17 | -- |
14 | Replace the HUD. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement? | -- | Go to Step 17 | -- |
15 | 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 17 | -- |
16 | 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 17 | -- |
17 | Operate the system in order to verify the repair. Use the scan tool in order to clear the DTCs that may have set in other modules during diagnosis. Did you correct the condition? | -- | System OK | Go to Step 2 |
