Pinpoint Test V: The Anti-Theft Indicator Is Never/Always On
Normal Operation
The Instrument Cluster (IC) controls the Passive Anti-Theft System (PATS) with the PCM and receives the anti-theft key status from the hardwired PATS transceiver. If there is a PATS concern, the IC anti-theft indicator glows steadily for one minute then flashes a 4-digit fault code 10 times when the ignition switch is turned to the ON position. The PATS also flashes the theft indicator approximately every 2 seconds at ignition OFF to act as a visual theft deterrent. Refer to Anti-Theft - Passive Anti-Theft System (PATS) Anti-Theft - Passive Anti-Theft System (PATS) for additional PATS information.
This pinpoint test is intended to diagnose the following:
- PATS concern
- IC
