Normal Operation
The instrument cluster controls the passive anti-theft system (PATS) with the powertrain control module (PCM) and receives the anti-theft key status from the hardwired PATS transceiver. If there is a PATS concern, the instrument cluster anti-theft indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the ignition switch is turned to the ON or START positions. The PATS also flashes the theft indicator every 2 seconds at ignition OFF to act as a visual theft deterrent.
This pinpoint test is intended to diagnose the following:

|---|---|---|---|
| STEP | INSPECTION | ACTION | |
| 1 | RETRIEVE THE RECORDED DTCs FROM BOTH THE CONTINUOUS AND ON-DEMAND INSTRUMENT CLUSTER SELF-TESTS
|
Yes | If PATS-related DTCs were retrieved, see DIAGNOSTIC TROUBLE CODE (DTC) INDEX - ANTI THEFT - PATS . For all other instrument cluster DTCs, see INSTRUMENT CLUSTER DIAGNOSTIC TROUBLE CODE (DTC) INDEX . |
| No | VERIFY the vehicle is equipped with PATS. Go to next step. | ||
| 2 | CONFIRM THE PATS FUNCTIONS CORRECTLY
|
Yes | Go to next step. |
| No | VERIFY the vehicle is equipped with PATS. | ||
| 3 | CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
|
Yes | INSTALL a new instrument cluster. See INSTRUMENT CLUSTER . 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. | ||
