Stop - Start system diagnostics

Stop - Starts system function relies on many parameters and it will never allow automated Stop- Start if all conditions are not properly set in the vehicle.

Analyze all parameters before changing parts. Think about the working conditions that could disable the system..brake vacuum reserve, electric parking brake, brake pedal, clutch pedal, engine operating temperature, better state of charge, power accumulator voltage, air conditioning and outside temperature, accelerator pedal etc..
