These w ill provide information regarding failure cause and location.
In this situation, the problem is probably due to an element that can act
only on one cylinder:
- Problem at injector
A cylinder is declared - Problem at spark plug
damaged : ET093 or ET094 - Problem at high voltage cable.
or ET095 or ET096. Before replacement, try the spark plug or cable changing to anothe r
cylinder.
Cy linders 1 and 4 or In this cylinders 2 and 3 declared situation, the proble m is probably
damaged : ET093 and ET 0 96 due to an eleme nt that can act only this pair of cylinders:
or ET094 and ET095. - Problem at ignition coil, at the high voltage part. - Problem at ignition coil, at the control part
In this situation, the problem is probably due to an element tha t can

1 10 CONTINUA TION
Ensure that all failures are solved. Erase all memorized failures.
There is no need to erase the “adaptive values” memoriz ed by the injection computer.
In order to check the correct reparation of the system, the following conditions must be
AF TER accomplished:
REPARATION - No more electrical failures;
- All “adaptive values” to be memorized by the injection computer;
- Warm engine (minimum 75°C);
- Run at idling, all consumers being in use for 20 minutes (1 minute DF110);
- If the failure is again occurring, repeat the dia gnostic.
