Check the resistance of the canister bleed valve.
Replace the valve if necessary.
Check, ignition on , for 12 V on track A of the canister bleed valve.
Repair if necessary.
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.
