Test F: Anti-Theft Number Of Programmed Keys Is Below Minimum

PINPOINT TEST F: ANTI-THEFT NUMBER OF PROGRAMMED KEYS IS BELOW MINIMUM

Test F1-F4:

Normal Operation
The transceiver module communicates with the passive anti-theft system (PATS) key. During each vehicle start sequence, the transceiver module reads the PATS key identification code and circuit 1216 (GY/OG) sends the data to the powertrain control module (PCM). The control functions are contained in the PCM. This module carries out all of the PATS functions, such as receiving the identification code from the PATS key and controlling engine enable. The PCM initiates the key interrogation sequence when the key is turned to ON or START.

Possible Causes
- less than 2 keys programmed to the system
- PATS transceiver
- unprogrammed PATS key
- PCM
