Pinpoint Test AH: The Anti-Theft Indicator Is Never/Always On

Normal Operation

The Instrument Panel Cluster (IPC) interacts with the PCM and controls the Passive Anti-Theft System (PATS) function. The IPC (Instrument Panel Cluster) controls the anti-theft indicator based upon the status of the PATS (Passive Anti-Theft System).

The anti-theft indicator proves out for 3 seconds when the key is turned to the ON or START position. If there is a PATS (Passive Anti-Theft System) concern, the anti-theft indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the ignition is switched to the ON or the START mode. The PATS (Passive Anti-Theft System) also flashes the anti-theft indicator every 2 seconds at ignition off to act as a visual theft deterrent for all vehicles.

This pinpoint test is intended to diagnose the following:

- PATS (Passive Anti-Theft System)

- IPC (Instrument Panel Cluster)

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

AH1 CARRY OUT THE IPC (Instrument Panel Cluster) ANTI-THEFT INDICATOR ACTIVE COMMAND USING THE SCAN TOOL

- Ignition ON.

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

- Select the IPC (Instrument Panel Cluster) anti-theft indicator (THEFT_LMP) active command. Command the anti-theft indicator on and off while observing the anti-theft indicator.

Does the anti-theft indicator illuminate when commanded on, and turn off when commanded off?

Yes
GO to AH2.

No
INSTALL a new IPC (Instrument Panel Cluster). REFER to Instrument Panel Cluster (IPC) . TEST the system for normal operation.

AH2 RETRIEVE THE RECORDED DTCs FROM THE CONTINUOUS IPC (Instrument Panel Cluster) SELF-TEST

- Check for recorded IPC (Instrument Panel Cluster) DTCs from the continuous self-test.

Are any PATS (Passive Anti-Theft System) -related DTCs recorded?

Yes
REFER to Antitheft and Alarm Systems.

No
INSTALL a new IPC (Instrument Panel Cluster). REFER to Instrument Panel Cluster (IPC) . TEST the system for normal operation.
