Keyless Entry: Description and Operation
The keyless entry system consists of the following:^ remote keyless entry [driver door module] module.
^ three button remote keyless entry transmitter (non-power sliding door vehicles).
^ four button remote keyless entry transmitter (single RR power sliding door vehicles).
^ five button remote keyless entry transmitter (dual power sliding door vehicles).
^ front electronic module.
^ rear electronic module.
The Remote Keyless Entry (RKE) operation uses the J1850 network and communication between the RKE Driver Door Module (DDM) and the Rear Electronic Module (REM). The RKE module receives a power sliding door activation command from the RKE transmitter and then transmits the command for the left or right power sliding door to the REM over the J1850 network. The REM will unlock the appropriate power sliding door and ground the appropriate remote open/close circuit to the power sliding door module. The RKE activation supplies a momentary ground signal to the appropriate power sliding door module commanding the power sliding door module to carry out an open, if conditions are correct, or close operation. The signal and data transmitted between the modules is not specific to open or close operation. The power sliding door module will determine which operation to carry out depending on the power sliding door position when the signal is received.
