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). The anti-theft 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 concern, the 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 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.

This pinpoint test is intended to diagnose the following:
- IC



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

NOTE: When a new IC is installed, the PATS keys must be programmed into the new IC.

NOTE: When a new IC is installed, the parameters must be reset in the IC 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 DataLogger.
- Trigger the IC active command ALL_LAMP (all warning lamps) to ON, then OFF.
- Does the anti-theft indicator illuminate, then turn off?

Yes
GO to F2.

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

-------------------------------------------------
F2 CHECK FOR CORRECT IC OPERATION


- Disconnect the IC connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the IC 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. RESET the parameters in both the IC and the PCM. REFER to Passive Anti-Theft System (PATS) Parameter Reset Passive Anti-Theft System (PATS). PROGRAM the PATS keys into the new IC. REFER to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment 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.
