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:

- IPC



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 Instrument Panel, Gauges and Warning Indicators. RESET the parameters in both the IPC and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset - Integrated Keyhead Transmitter (IKT) With Integrated Keyhead Transmitter (IKT). PROGRAM the PATS keys into the new IPC. REFER to Key Programming Using Diagnostic Equipment - Integrated Keyhead Transmitter (IKT) Integrated Keyhead Transmitter (IKT). 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 Instrument Panel, Gauges and Warning Indicators. RESET the parameters in both the IPC and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset - Integrated Keyhead Transmitter (IKT) With Integrated Keyhead Transmitter (IKT). PROGRAM the PATS keys into the new IPC. REFER to Key Programming Using Diagnostic Equipment - Integrated Keyhead Transmitter (IKT) Integrated Keyhead Transmitter (IKT). 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. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
