Pinpoint Test H: 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 anti-theft indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the key is turned to the ON or the 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 is controlled by the IC (Instrument Cluster).

This pinpoint test is intended to diagnose the following:

- IC (Instrument Cluster)

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

H1 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 IC (Instrument Cluster) active command THEFT_LMP to on, then off.

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

Yes
GO to H2.

No
INSTALL a new IC (Instrument Cluster). TEST the system for normal operation.

H2 CHECK FOR CORRECT IC (Instrument Cluster) OPERATION

NOTE: When using the Integrated Diagnostic System (IDS), the IC (Instrument Cluster) and the Transmission Control Module (TCM) parameters are reset at the same time.

- 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). CARRY OUT the parameter reset procedure on both modules. REFER to Passive Anti-Theft System (PATS) Parameter Reset . PROGRAM the PATS keys into the new IC (Instrument Cluster). REFER to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment . CLEAR the DTCs. 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.
