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:

- PATS (Passive Anti-Theft System) concern

- IC (Instrument Cluster)

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

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

F1 CHECK THE DTCs

- Ignition OFF.

- Connect the scan tool.

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: Retrieve the IC (Instrument Cluster) DTCs.

Are there any IC (Instrument Cluster) DTCs retrieved?

Yes
REFER to DTC Charts. Antitheft and Alarm Systems

No
GO to F2.

F2 CHECK THE ANTI-THEFT INDICATOR FOR CORRECT OPERATION

- Ignition OFF.

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: IC (Instrument Cluster) DataLogger.

- Turn the active command THEFT_LMP to on then off.

Does the anti-theft indicator illuminate then turn off?

Yes
GO to F3.

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 Key Programming Using Diagnostic Equipment . CYCLE the ignition. REPEAT the self-test.

F3 CHECK FOR CORRECT IC (Instrument Cluster) OPERATION

- Disconnect all the IC (Instrument Cluster) connectors.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect all the IC (Instrument Cluster) connectors and make sure they seat 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 Key Programming 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. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
