Pinpoint Test AD: The Passive Anti-Theft System (PATS) Indicator Is Never/Always On

Normal Operation

The Passive Anti-Theft System (PATS) uses a visual anti-theft indicator located in the Instrument Cluster (IC). This 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 the START position. PATS also flashes the anti-theft indicator every 2 seconds at key off to act as a visual theft deterrent. The anti-theft indicator is controlled by the IC.

This pinpoint test is intended to diagnose the following:

- PATS concern
- IC
