9-5 Sedan (9600) L4-2.3L Turbo (B235) (2000)
When the control module is supplied with current, its processor is turned on. The processor then reads the instructions stored in the control module
memory.
The control module is programmed to read the inputs and activate the outputs. If the control module program is faulty, the diagnostic trouble code
"Internal Control Module Fault" will be generated.
The control module must be supplied with current for the system to be operative. The control module is supplied with current and the processor turned
on when the control module can be contacted by the diagnostics instrument.
Outputs
The purpose of the system is to control a number of functions via various actuator units, e.g. an injector or bulb. For the system to be capable of
performing its functions, it must be possible to activate the actuator units. The actuator units must therefore be connected to the control module and have
the correct power supply or connection to ground.
Inputs
Before the control module can control its actuators, the system sensors must supply it with the correct values.
The function of the sensors can be tested using the diagnostics instrument.
