The glow plug control module determines the timing and electric current required by the glow plugs based on input from the Engine Control Unit.When you start up a diesel-powered vehicle, the following actions happen: The current to the glow plugs is turned on during the pre-heating to warm up the engine, stand-by time when the engine should be started, and post-heating to meet increasingly strict exhaust gas standards and optimisation of combustion processes. This includes when to switch the current for the glow plugs on and off, and how much current is required as this will differ depending on the starting temperature of the engine. Located on the engine and with a direct connection to the engine control unit, the control module uses a microprocessor to analyse input from the engine control unit to determine information related to the working of the glow plugs. But how is the overall operation of your glow plugs monitored and controlled? This is done by a glow plug control module. As you already know, a glow plug is a heating device in each cylinder of a diesel engine that helps the engine to start.
