Anti-Theft

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 Cluster (IC). This 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 (Passive Anti-Theft System) concern, this indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the key is turned to the ON or START position. PATS (Passive Anti-Theft System) 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 IC (Instrument Cluster).

This pinpoint test is intended to diagnose the following:

- IC (Instrument Cluster)

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

NOTE: When a new IC (Instrument Cluster) is installed, the PATS (Passive Anti-Theft System) keys must be programmed into the new IC (Instrument Cluster).

NOTE: When a new IC (Instrument Cluster) is installed, the parameters must be reset in the IC (Instrument Cluster) 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: IC (Instrument Cluster) DataLogger.

- Trigger the active command THEFT_LMP to ON, then OFF.

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

Yes
GO to F2.

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

F2 CHECK FOR CORRECT IC (Instrument Cluster) OPERATION

- Disconnect the IC (Instrument Cluster) connector.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect the IC (Instrument Cluster) 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 IC (Instrument Cluster). RESET the parameters in both the IC (Instrument Cluster) and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset . PROGRAM the PATS (Passive Anti-Theft System) keys into the new IC (Instrument Cluster). REFER to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment . CYCLE the ignition. REPEAT the self-test. 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. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
