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 under normal operation. If there is a PATS issue, 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:

PINPOINT TEST F: THE ANTI-THEFT INDICATOR IS ALWAYS/NEVER ON

NOTE: When a new IPC is installed, the PATS keys must be programmed into the new IPC and the parameters must be reset in the IPC and the PCM.

-------------------------------------------------
F1 CHECK THE ANTI-THEFT INDICATOR FOR CORRECT OPERATION

- Ignition OFF.
- Connect the scan tool.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: IPC DataLogger.
- Trigger the IPC active command THEFT_LMP (theft lamp) to ON, then OFF.
- 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). TEST the system for normal operation.

-------------------------------------------------
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). TEST the system for normal operation.

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