Keyless entry power??
Selkirk, couldn't send you a pm (maybe your inbox is full!). For the rest of you who can't get PM's, here is the info I recieved, hope it helps you out!
SECTION 501-14B: Keyless Entry/Computer Operated Locks
1999 Expedition/Navigator Workshop Manual
DIAGNOSIS AND TESTING
--------------------------------------------------------------------------------
Keyless Entry
****** content="Keyless Entry" name="tps_proctitle"> Refer to Wiring Diagrams Cell 117 , Remote Control Alarm and Lock System for schematic and connector information.
Special Tool(s) 73 Digital Multimeter
105-R0051 or equivalent
New Generation STAR (NGS) Tester
418-F048 (007-00500) or equivalent
Principles of Operation
When a keyless entry remote transmitter switch is depressed, it transmits a radio signal to the remote anti-theft personality (RAP) module, which, in turn, grounds the coil circuit for the all door lock relay, the all door unlock relay or the liftgate unlock relay. The appropriate relay then closes and completes the power circuit to the respective door lock actuators. If the panic switch is depressed on the remote keyless entry transmitter, the RAP module will trigger the panic feature.
When a keyless entry keypad switch is depressed, it completes the respective circuit to the key switch common circuit, which then signals the RAP module that a particular number key switch has been depressed. If the appropriate sequence of keyless entry keypad switches are depressed, the RAP module will then lock or unlock all the doors, unlock the driver door or unlock the liftgate.
The autolocking feature locks all doors when all doors are closed, the ignition is in run, the transmission is in either a forward or reverse gear and vehicle speed is 5 miles per hour or higher. If any door becomes ajar, this feature will relock all doors when the ajar door is returned to a closed position and all previous conditions are met.
When the RAP module receives an unlock command from the keyless entry remote transmitter and the memory seat function is enabled, it sends a signal to the driver seat module (DSM) indicating which keyless entry remote transmitter is being used (one or two). The DSM then adjusts the driver seat and mirrors according to the preset position information.
When the keyless entry remote transmitter unlock switch is depressed and it sends an unlock command to the RAP module, the RAP module then sends a signal to the GEM, which then initiates the illuminated entry feature.
Inspection and Verification
Verify the customer concern by operating the keyless entry/computer operated locks.
Visually inspect for obvious signs of mechanical and electrical damage.
Visual Inspection Chart Mechanical Electrical
Binding latch mechanisms
Binding linkage
Misaligned door
Central junction box (CJB)
Fuse 4 (15A)
Fuse 8 (5A)
If the concern remains after the inspection, connect the New Generation STAR (NGS) Tester to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from NGS Tester menu. If NGS Tester does not communicate with the vehicle:
check that the program card is properly installed.
check the connections to the vehicle.
check the ignition switch position.
If NGS Tester still does not communicate with the vehicle, refer to the New Generation STAR Tester manual.
Perform the DATA LINK DIAGNOSTIC TEST. If NGS Tester responds with:
CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section 418-00 .
NO RESP/NOT EQUIP for RAP, go to Pinpoint Test D. NO RESP/NOT EQUIP for GEM, go to Pinpoint Test F.
SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the RAP module, and GEM.
If the DTCs retrieved are related to the concern, go to RAP Module Diagnostic Trouble Code (DTC) Index to continue diagnostics and GEM Diagnostic Trouble Code (DTC) Index.
If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics.
