9K-4 Rear Glass Release W/Ign In "Run" and Trans. Out of "Park"

CIRCUIT DESCRIPTION
When the Remote Control Door Lock Receiver (RCDLR) senses no voltage on CKT 693 and CKT 275, the rear glass release function can be activated using the transmitter. When the RCDLR senses voltage on CKT 639 and CKT 275, (ignition switch in "RUN" and A/T in "PARK") the rear glass release function can also be activated using the transmitter. When the RCDLR senses voltage on CKT 639 (ignition switch in RUN") and no voltage on CKT 275 (A/T not PARK) the rear glass release function cannot be activated by the transmitter.

CHART TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.
1. Check for an ignition input signal to the RCDLR.
2. Check for a false signal from the backup lamp and transmission position (Park/Neutral Position (PNP)) switch or a short to voltage on CKT 275.
