Testing Possible Causes of Transmission Control Faults

Before performing a symptom-based diagnosis, first carry out checks to eliminate various other potential causes of the fault.

These situations include:

  • Battery state of charge
  • Defective fuses
  • Loose or corroded cables or electrical connectors
  • Ground connections to the transmission
  • Retrofitted add-on units which are not approved by Ford, such as air conditioning, car telephone, cruise control
  • Unapproved tire sizes
  • Incorrect tire size programmed with IDS (Integrated Diagnostic System)
  • Engine tuning

IDS Diagnosis

NOTE: Customer concerns relating to the transaxle can also be caused by engine-related faults.

The transmission control system of the AW55 is closely linked to the engine management system.

Faults in the engine management system may affect the transmission control system.

Before repairing the transaxle, it should be ensured that the fault is not caused by the engine management system or other non-transaxle components.

The diagnosis can be performed on the AW55 with the aid of von IDS.
