Diagnostic Overview 

Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to Diagnostic Methods in Service Information for information about these practices.

Normal Operation and Fault Conditions 

The factory equipped remote start system enables the engine to be started from up to 100 meters (328 feet) away by pressing a sequence of buttons on theIKT or IA key. To activate the remote start system, press the lock button once to make sure the doors are locked, followed by 2 presses of the remote start button. The 3 button presses must occur within 3 seconds of each other. The IKT or IA key signal is received through an external antenna attached to the Tire Pressure Monitor Module (TPM) and communicated over the Medium Speed Controller Area Network (MS-CAN) to initiate the vehicle start.
