Visual Inspection
Visual InspectionThis inspection will identify modifications or additions to the vehicle operating system that may affect diagnosis. Inspect the vehicle for non-Ford factory add-on devices such as:
^ NON OEM electronic add-on items:
- Remote starter equipment
- Air conditioning
- Generator (alternators)
- Engine turbo
- Cellular telephone
- Cruise control
- CB radio
- Linear amplifiers
- Backup alarm signal
- Computer
^ Vehicle modification:
- These items, if not installed correctly, will affect the powertrain control module (PCM), or transaxle function. Pay particular attention to add-on wiring splices in the PCM harness or transaxle wiring harness, abnormal tire size, or axle ratio changes.
- Damaged, bent, broken or loose fluid cooler tubes.
- Leaks.
- Correct linkage adjustments.
Shift Linkage Check
Check for a misadjustment in shift linkage by matching the detents in the transmission range selector lever with those in the transmission. If they match, the misadjustment is in the indicator. Do not adjust the shift linkage.
Hydraulic leakage at the manual control valve can cause delay in engagements and/or variator slipping while operating, if the linkage is not correctly adjusted.
Check TSBs
Refer to all technical service bulletins which pertain to the concern and follow the procedure.
Carry Out On-Board Diagnostics (KOEO, KOER)
After a road test, with the vehicle warm and before disconnecting any connectors, carry out the Quick Test using the diagnostic tool. Refer to Computers and Control Systems for diagnosis and testing of the powertrain control system.
