Hi!
In this video I will show you the renault scenic 2002 1.6i reacted.
The car wouldn't start and the engine control unit wouldn't come up for diagnosis .
1. Connect the scanner and read the errors. Unit won't come up for diagnosis.
2. Check the power supply to the engine control unit.
3. See that instead of 12 volts, it's only 3.5 volts. This means a bad contact or a damaged wire somewhere.
4. Locate the fault and repair it.
5. 5. Start the car. Congratulations.
