For certain faults BG 6LH will only illuminate permanently at 3000 rpm. for 1
minute. If BG 4LH or BG 5LH is also illuminated, check line 44 of the computer.
NOTES
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 pinking sensor.

Check the resistance of the value for the two faulty injectors.
Replace the injector/s if necessary.
When the ignition is switched on and during the timed phase, check for 12 V on track 1 of the faulty
injector.
If necessary, repair the line from track 1 injector to track 5 fuel pump relay.
The fault persists! Replace the injection computer.
