Pinpoint Test F: The Anti-Theft Indicator Is Always/Never On

Normal Operation

The Passive Anti-Theft System (PATS) uses a visual anti-theft indicator located in the Instrument Panel Cluster (IPC). The anti-theft indicator proves out for 3 seconds when the key is turned to the ON or START position. If there is a PATS concern, the 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. 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 IPC.

This pinpoint test is intended to diagnose the following:

- IPC

- Does the anti-theft indicator illuminate, then turn off?

Yes
GO to F2.

No
INSTALL a new IPC. REFER to Instrumentation, Message Center, and Warning Chimes Instrument Panel Cluster (IPC). RESET the parameters in both the IPC and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset Passive Anti-Theft System (PATS) Parameter Reset. PROGRAM the PATS keys into the new IPC. REFER to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. CYCLE the ignition. REPEAT the self-test.

-------------------------------------------------
F2 CHECK FOR CORRECT IPC OPERATION

- Disconnect the IPC connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the IPC connector and make sure it seats correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?

Yes
INSTALL a new IPC. REFER to Instrumentation, Message Center, and Warning Chimes Instrument Panel Cluster (IPC). RESET the parameters in both the IPC and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset Passive Anti-Theft System (PATS) Parameter Reset. PROGRAM the PATS keys into the new IPC. REFER to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. CYCLE the ignition. REPEAT the self-test.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. TEST the system for normal operation.
