Test F

PINPOINT TEST F: THE ANTI-THEFT SYSTEM DOES NOT OPERATE CORRECTLY - PATS IGNITION KEY TRANSPONDER SIGNAL IS NOT RECEIVED OR TRANSPONDER PROGRAMMING FAILED (DAMAGED KEY OR NON-PATS KEY)

Test F1-F3:

Normal Operation
The transceiver module communicates with the PATS key. The control functions are contained in the instrument cluster. This instrument cluster carries out all of the PATS functions such as receiving the identification code from the PATS key and controlling starter enable. The instrument cluster initiates the key interrogation sequence when the key is inserted in the ignition when the key is turned to RUN or START.

Possible Causes
- instrument cluster
- PATS transceiver
- PATS key
