REMOTE KEYLESS ENTRY
DIAGNOSIS AND TESTING (Continued)
Doors will lock with the key fob transmitter but
there is no horn CHIRP.
(1) Press horn button, listen horn sound.
(2) If the horn does not CHIRP, check if horn is
disabled with the scan tool (DRB). Then check the
horn relay and the horn(s). Repair as necessary.
(3) Using a voltmeter, check horn relay for voltage
pulse. Press the lock button on the key fob transmit-
ter.
(4) If no voltage pulse measured, replace the BCM.
If voltage is measured, repair harness to the horn
relay.
Unable to program BCM with a new key fob
transmitter, door locks will not cycle.
Refer to the proper Body Diagnostic Procedure
Manual.
Unable to program BCM with a new key fob

SERVICE PROCEDURES
HORN CHIRP ENABLE/DISABLE
The scan tool (DRB) must be used to enable/disable
the Horn Chirp. Refer to the scan tool (DRB) for the
procedure.
SYNCHRONIZATION OF ROLLING CODE
The key fob transmitter code will go out of syn-
chronization if any button is press more than 250
times outside the range of the receiver which is
inside of the BCM. In other words the transmitter
will not work. To synchronize the code of a particular
key fob transmitter with the receiver, press and hold
the lock button then the deck lid button simulta-
neously for at lease five seconds. Then wait until the
doors unlock indicating that the code has been syn-
chronized. This may take as long as six minutes.
This is for a key fob transmitter that has been pre-
viously programed to this vehicle only.
