On vehicles equipped with a Gasoline Turbo Direct Injection (GTDI) engine, the IPC provides a message to inform the driver that vehicle performance is reduced to allow the engine to cool. This feature is part of the smart cooling function in the PCM and provides powertrain cooling protection under high ambient temperature conditions.
The IPC receives the powertrain cooling message request from the GWM over the HS-CAN3. The GWM receives the powertrain cooling message request from the PCM over the HS-CAN1.
