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 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 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.

This pinpoint test is intended to diagnose the following:

- IC



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 DataLogger.
- Trigger the IC active command ALL LAMPS to on, then off.
- Does the anti-theft indicator illuminate, then turn off?

Yes
GO to H2.

No
INSTALL a new IC. TEST the system for normal operation.

-------------------------------------------------
H2 CHECK FOR CORRECT IC OPERATION


NOTE: When using the IDS, the IC and the TCM parameters are reset at the same time.

- Disconnect all the IC connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect all the IC 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. CARRY OUT the parameter reset procedure on both modules. REFER to Passive Anti-Theft System (PATS) Parameter Reset Passive Anti-Theft System (PATS). PROGRAM the PATS keys into the IC. REFER to Integrated Keyhead Transmitter (IKT) Key Programming Using Diagnostic Equipment 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. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
