Pinpoint Test Q: 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 ignition is transitioned to the ON or START position. If there is a PATS concern, the anti-theft indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the ignition is transitioned to the ON or the 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 when the Remote Function Actuator (RFA) module sends a message to the IPC over the Medium Speed Controller Area Network (MS-CAN).

This pinpoint test is intended to diagnose the following:

- IPC
- RFA module



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

-------------------------------------------------
Q1 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 ( PATS indicator control only) to ON, then OFF.
- Does the anti-theft indicator illuminate, then turn off?

Yes
GO to Q2.

No
INSTALL a new IPC. REFER to Instrument Panel, Gauges and Warning Indicators. CYCLE the ignition. REPEAT the self-test.

-------------------------------------------------
Q2 CHECK THE RFA MODULE


- Ignition OFF.
- Disconnect: RFA Module C2153D.
- Ignition ON.
- Operate the system and verify the concern is still present.
- Is the concern still present?

Yes
GO to Q3.

No
GO to Q4.

-------------------------------------------------
Q3 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. 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. TEST the system for normal operation.

-------------------------------------------------
Q4 CHECK FOR CORRECT RFA MODULE OPERATION


- Disconnect all the RFA module connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the RFA module 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 RFA module. REFER to Body Control Systems. RESET the parameters in both the RFA module and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset - Intelligent Access (IA) With Intelligent Access (IA). PROGRAM the IA keys into the new RFA module. REFER to Key Programming Using Diagnostic Equipment - Intelligent Access (IA) With Intelligent Access (IA). 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. TEST the system for normal operation.
