Circuit / System Description

WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.

Remote vehicle start (RVS) begins as an RF message received by the remote control door lock receiver (RCDLR) from a keyless entry transmitter. The RVS request is sent by the RCDLR to the body control module (BCM) via serial data. The BCM monitors system conditions such as content theft deterrent (CTD), hood ajar status, and body DTCs to determine if an RVS even will occur. If conditions are determined to be acceptable, the RVS message is sent to the powertrain control module (PCM). The PCM monitors system conditions such as engine control parameters and vehicle theft deterrent (VTD) to determine if engine starting will be allowed. If conditions are acceptable, the PCM will initiate engine starting. During the engine run time in a RVS attempt, before the operator enters the vehicle, the PCM may discontinue engine operation if system conditions require it or a message is received from the BCM requesting the engine be turned OFF.
