Normal Operation
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
During each vehicle start sequence, when the key is turned to the START or ON position, the Passive Anti-Theft System (PATS) transceiver reads the PATS key identification code and sends the data to the Instrument Panel Cluster (IPC). If the concern is due to a PATS concern, PATS DTCs should be set in the IPC and DTC P1260 in the PCM. If it is due to a starting system, or a driveability concern, there is no PATS DTCs in the IPC or DTC P1260 in the PCM.
This pinpoint test is intended to diagnose the following:
- Starting system concern
- PATS concern
