Test A

PINPOINT TEST A: THE ANTI-THEFT INDICATOR IS ALWAYS/NEVER ON - ENGINE CRANKS, BUT NO THREE SECOND THEFT INDICATOR PROVE-OUT

Test A1-A4:

Test A4-A6:

Normal Operation
The PATS uses an LED indicator. This indicator will prove out for 3 seconds when the ignition switch is turned to ON or START under normal operation. If there is a PATS concern, this indicator will either flash rapidly or glow steadily (for more than 3 seconds) when the ignition switch is turned to ON or START. PATS also "flashes" the theft indicator every 2 seconds at key OFF to act as a visual theft deterrent.

Possible Causes
- anti-theft LED is inoperative
- PCM
- circuit 1768 (OG/RD)
- circuit 343 (DB/LG)
