WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
- Verify the customer concern.
- Visually inspect the following for obvious signs of mechanical or electrical damage. VISUAL INSPECTION CHART
Mechanical Electrical - Throttle body
- Auxiliary relay box fuse F01 (5A)
- Central junction box (CJB) fuse(s):
- 2 (20A)
- 14 (10A)
- Circuitry
- Speed control switch
- Stoplamp switch
- Speed control deactivator switch
- Clutch pedal position (CPP) switch
- Powertrain control module (PCM)
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- Verify the speedometer operates correctly without speed control by test driving the vehicle. If the speedometer does not operate correctly, refer to INSTRUMENT CLUSTER article.
- Verify the stoplamps operate correctly with the ignition switch in the ON position. If the stoplamps do not operate correctly, refer to EXTERIOR LIGHTING article.
- Verify the parking brake warning indicator is operating correctly. If the parking brake warning indicator does not operate correctly, refer to INSTRUMENT CLUSTER article.
- If the cause is not visually evident, connect the scan tool to the data link connector (DLC).
- If the scan tool does not communicate with the VCM:
- Check the VCM connection to the vehicle.
- Check the scan tool connection to the VCM.
- Refer to MODULE COMMUNICATIONS NETWORK article, No Power To The Scan Tool, to diagnose no communication with the scan tool.
- If the scan tool does not communicate with the vehicle:
- Verify the ignition key is in the ON position.
- Verify the scan tool operation with a known good vehicle.
- Refer to MODULE COMMUNICATIONS NETWORK article to diagnose no response from the PCM.
- Carry out the network test:
- If the scan tool responds with no communication for one or more modules, refer to MODULE COMMUNICATIONS NETWORK article.
- If the network test passes, retrieve and record the continuous memory DTCs.
- Clear the continuous DTCs and carry out the self-test diagnostics for the PCM.
- If the DTCs retrieved are related to the concern, go to the Powertrain Control Module (PCM) Diagnostic Trouble Code (DTC) Index. For all other DTCs, refer to MULTIFUNCTION ELECTRONIC MODULES article.
- If no DTCs related to the concern are retrieved, go to Symptom Chart .POWERTRAIN CONTROL MODULE (PCM) DIAGNOSTIC TROUBLE CODE (DTC) INDEX
