G2-G4:
Normal Operation
The PATS uses a visual anti-theft indicator located on top of the instrument panel. The PATS anti-theft indicator receives voltage from the powertrain control module (PCM) through circuit 343 (DB/LG) and proves out for 3 seconds when the key is turned to ON or START under normal operation. If there is a PATS issue, the indicator either flashes rapidly or glows steadily (for more than 3 seconds) when the key is turned to ON or START. PATS also flashes the anti-theft indicator every 2 seconds at ignition OFF to act as a visual anti-theft deterrent.
Possible Causes
- fuse
- circuit 1269 (OG/RD) open
- circuit 1523 (DG) open or short to ground
- anti-theft indicator
- powertrain control module (PCM)
