Pinpoint Test Z: The Anti-Theft Indicator Is Never/Always On
Normal Operation
The Instrument Panel Cluster (IPC) interacts with the PCM (non-hybrid) or Transmission Control Module (TCM) (hybrid) and controls the Passive Anti-Theft System (PATS) function. The IPC controls the anti-theft indicator based upon the status of the PATS.
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 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 START mode. The PATS 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 concern
- IPC
PINPOINT TEST Z: THE ANTI-THEFT INDICATOR IS NEVER/ALWAYS ON
-------------------------------------------------
Z1 CHECK THE ANTI-THEFT INDICATOR OPERATION
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: IPC DataLogger.
- Select the IPC 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 Z2.
No
INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) Instrument Panel Cluster (IPC). TEST the system for normal operation.
-------------------------------------------------
Z2 RETRIEVE THE RECORDED DTCs FROM THE CONTINUOUS IPC SELF-TEST
- Check for recorded IPC DTCs from the continuous self-test.
- Are any PATS-related DTCs recorded?
Yes
REFER to Anti-Theft - Passive Anti-Theft System (PATS) Testing and Inspection.
No
INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) Instrument Panel Cluster (IPC). TEST the system for normal operation.
