DESCRIPTION
This bulletin describes RKE (Remote Keyless Entry) basic diagnosis and remote programming.
NOTE:
2001 and later vehicles allow Lock and Unlock functions to operate with the ignition ON. However flashing of exterior lights or chirp of the horn is
prevented with the key in RUN or START.
2001 and later B-Series Trucks have a feature called Power Door Lock Disable, which becomes active 20-seconds after the vehicle is electronically
locked. The feature is used to prevent access into the vehicle if a moon roof or window is open and someone attempts to activate the power door lock
switch with a stick. Power door locks operate again after the vehicle is unlocked with the remote or a door becomes ajar. If a customer complains of
intermittent interior power door lock operation, check to see if this feature is configured on by verifying the conditions listed above. This feature can
be turned on and off using a procedure in the vehicle's owner guide.
BASIC DIAGNOSIS
1.
Poor Range Performance:
a.
Verify that this is a factory installed keyless entry system before pursuing warranty repairs. The figure identifies a typical factory remote,
part number would be the best method of verifying the system is factory.
b.
Do not change batteries in the remote, (range does not change as batteries age).
c.
Verify that poor range affects all remotes:
^
If condition affects all remotes go to STEP d.
^
If some remotes operate at a greater distance, replace the one bad transmitter and reprogram all transmitters.
d.
Ensure the poor performance is not only in certain locations.
Examples: near radio stations/transmitters, TV stations/transmitting towers, military bases, power generators, substations or transformers.
These locations may have RFI (Radio Frequency Interference) that interferes with normal remote operation.
e.
Ensure poor performance is consistent in nature and not just from one approaching angle from or to the vehicle.
