B4000 Regular Cab 4WD V6-4.0L OHV (1997)
Remote Keyless Entry
Operation - Remote Keyless Entry (GEM ONLY)
The all unlock relay sends a door lock position signal to the GEM. The GEM uses this signal for the battery saver function.
Operation - Two-Step Unlock
When the remote transmitter sends a disarm signal to the RAP module, the RAP module sends a signal to the GEM. The GEM sends a signal back to
the RAP module to close the driver unlock relay. When the driver unlock relay closes, current is sent to the driver door lock actuator, opening the
driver door.
If the remote transmitter sends a second disarm signal to the RAP module, the RAP module sends another signal to the GEM. The GEM sends a signal
back to the RAP module to close the all unlock relay. When the all unlock relay closes, current is sent to both door lock actuators, opening both doors.
