PINPOINT TEST D: DATA MISMATCH (RECEIVED DATA DOES NOT MATCH WHAT WAS EXPECTED)

Test D1-D2:

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 engine enable. The instrument cluster initiates the key interrogation sequence when the key is inserted in the ignition cylinder and when the key is turned to RUN or START.

Possible Causes
- PCM calibration
- instrument cluster calibration
- instrument cluster
