Does the BCM and the RKE communicate with each other or the TECH 2 on the Class 2 data line?
The RKE must communicate with the BCM to lock and unlock the doors.
Sometimes the tech can call techline and get a programming number when TIS does not have the option available for programming.

GMMerlin,

Thanks a lot for the reply. It is much appreciated.
The car did not have remote access originally. I purchased the RKE receiver and remote for this model car, and ran power to the RKE receiver, which is always powered up. I also ran a spice to the serial data bus that the BCE uses to communicate with other devices. I found the circuit schematic in the service manual for wiring the RKE receiver. The schematic indicated that 3 wires were needed, ground, fused 12 V positive, and a serial data bus wire.
I did take the car to the dealer and they let me into the service area. The Tech 2 recognizes the transmitter thru the receiver and serial data bus, however, the receiver does not communicate with the BCM to activate opening and closing the door locks and trunk. In the past, I've gotten the receiver and transmitter to recognize/synchonize with each other on the bench by applying power and using an oscilloscope to watch the output signal on the data bus wire by pressing both the lock and unlock buttons. I assume that the BCM has to be reprogrammed to accept the RKE receiver. I've been told by the dealer that they would have to install a new BCM for this to work. I'm not convinced, as I believe the BCM could be reprogrammed or reflashed to include the remote access option. There was an earlier post that alluded to reflashing the BCM module. I don't know what is involved in reflashing the BCM Module, but I thought that the Service Tech would use the TECH 2 Scanner and vehicle options codes located in the truck area (along the with the new option remote access code "AUO") to reprogram the BCM. I don't have access to a TECH 2 Scanner, so I don't know what to ask or tell the dealer to do. They've already charged me $50 for the last failed attempt.
I'm sorry this is a little long, but I wanted to present as much info as possible. I would appreciate any help.
Thanks,
don
