Normal Operation

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The Passive Anti-Theft System (PATS) uses a visual anti-theft indicator located in the Instrument Cluster (IC). This anti-theft indicator proves out for 3 seconds when the key is turned to the ON or START position under normal operation. If there is a PATS  concern, this anti-theft indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the key is turned to the ON or START position. Retrieve DTCs from the IC  and the Transmission Control Module (TCM) to determine if there are any PATS  -related DTCs that can indicate the cause of the no-start.

A PATS  no-start can involve a vehicle no-start due to either the fuel injectors not operating or the Electronically Controlled Continuously Variable Transmission (eCVT) not cranking the engine (or both). A low battery voltage can cause the PATS  to allow the eCVT  to crank the engine, but can keep the fuel injectors from operating. Also, a key read concern can keep the fuel injectors from operating, while a TCM  -PCM ID concern can be at fault if there is no starter operation, although a key read concern can also be the cause of an inoperative eCVT  (starter). PATS  also flashes the anti-theft indicator every 2 seconds at key off to act as a visual theft deterrent. The anti-theft indicator operation is controlled by the IC  .

This pinpoint test is intended to diagnose the following:
