Normal Operation
The PATS transceiver receives voltage from the smart junction box (SJB) on circuit CBP18 (GY/OG) and is grounded on circuit GD116 (BK/VT). The PATS transceiver and the instrument cluster communicate on circuits VRT23 (VT/GY) and VRT24 (YE/OG). The instrument cluster compares the keycode stored in memory and sends a message over the controller area network (CAN) to the powertrain control module (PCM) to start the vehicle if the key code is correct.

Possible Causes
- fuse
- circuit CBP18 (GY/OG) open or short to ground
- circuit GD116 (BK/VT) open
- circuit VRT23 (VT/GY) open or short to ground
- circuit VRT24 (YE/OG) open or short to ground
- PATS transceiver
- instrument cluster
