injector.
If necessary, repair the line from track 1 injector to track L5 fuel pump relay.
The fault persists! Replace the injection computer.
IMPORTANT: The computer has probably been damaged by an electric shock. The cause of the damage
must be found before fitting a new computer.
The fault persists! Replace the faulty injector.
NOTE : Check the insulation and continuity of the lines for the other injectors and also check the
resistance of these injectors.
