CIRCUIT DESCRIPTION
In passive mode and on reception of a valid transmitter coming into range, the PKE receiver will apply B+ to terminal "B" (also terminal "H" if the unlock both doors mode has been selected) to the left door lock actuator on CKT 694 (also CKT 1663 if the unlock both doors mode has been selected). With the passive mode "OFF" or "ON", the PKE receiver will apply B+ to terminal "H" when the transmitter door button is depressed. When a door lock switch is depressed to the "unlock" position, B+ is input to terminal "A" and passed through to terminals "B" and "H". In passive mode, on reception of a valid transmitter leaving range, the PKE receiver will apply B+ on terminal "D" locking both doors. When the lock switch is depressed to the "lock" position, B+ is input on terminal "G" at the PKE receiver and passed through on terminal "D" to power both door lock motors.

CHART TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.
1. Determines if the PKE receiver is sending a "lock" command on terminal "D."
2. If CKT 1376 (Universal Theft Deterrent (UDT) status) is open or if the PKE receiver is not applying approximately 5 volts to terminal "B7" the PKE system will not function. This test will determine if an open is present in CKT 1376 or if the PKE receiver is not applying approximately 5 volts to terminal "B7."
