J1 - J2:

J2 - J4:

Normal Operation
During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and circuit 1216 sends the data to the instrument cluster.

Possible Causes
^ PATS transceiver
^ circuitry
^ instrument cluster
^ electronic-encoded ignition key
