Normal Operation
The passive anti-theft system (PATS) uses an anti-theft indicator. This indicator proves out for 3 seconds when the ignition switch is in 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 ignition switch is in the ON or START position.

Possible Causes
- powertrain control module (PCM) calibration
- PCM
- instrument cluster
