Circuit/System Description

The Vehicle Theft Deterrent (VTD) System is incorporated within the remote control door lock receiver (RCDLR). If the RCDLR has been replaced, the password must be relearned by the engine control module (ECM). If the ECM is replaced, the replacement ECM should learn the password within a few seconds after the ignition is turned ON. This is an information code indicating that the ECM is ready to learn the VTD password.
