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 then goes out to indicate PATS is functional and the vehicle has been enabled. If there is a PATS 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 also flashes the anti-theft indicator every 2 seconds at key off to act as a visual theft deterrent. If the vehicle is equipped with PATS, the anti-theft indicator flashes every 2 seconds for 10 seconds, then it goes out and stays off with the key in the OFF position. With a non-PATS vehicle and with the key in the ON position, the anti-theft indicator proves-out for 3 seconds, then goes out to indicate the vehicle has been enabled. If the vehicle is equipped with PATS or is not equipped with PATS, 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 both 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 THEFT_LMP to on, then off.
- Does the anti-theft indicator illuminate, then turn off?
Yes
GO to F2.
No
INSTALL a new IC. REFER to Instrument Panel, Gauges and Warning Indicators. RESET the parameters in 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 Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. CYCLE the ignition. REPEAT the self-test.
-------------------------------------------------
F2 CHECK FOR IC DTCs
- Retrieve the IC DTCs (if present).
- Were any IC DTCs retrieved?
Yes
REFER to DTC Charts.
No
GO to F3.
-------------------------------------------------
F3 CHECK FOR CORRECT IC OPERATION
- 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. REFER to Instrument Panel, Gauges and Warning Indicators. 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 Key Programming Using Diagnostic Equipment Using Diagnostic Equipment. 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.
