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 indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the key is turned to the ON or 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 operation is controlled by the IC . If there is a High Speed Controller Area Network (HS-CAN) concern, or a PATS concern, the anti-theft indicator in the IC flashes and the vehicle experiences a PATS no-start.
This pinpoint test is intended to diagnose the following:
- Starting system concern
- PATS concern
