SPECIAL NOTES FOR MULTIPOINT INJECTION
•55 track SIEMENS FENIX 5 computer.
•Injection cylinder by cylinder (sequential).
•Static ignition with two coils.
•Canister bleed solenoid controlled by RCO signal.
•Idle speed correction depending on:
- battery voltage,
- air conditioning,
- heated windscreen.
•Injection warning light on instrument panel operational.
•Use fault finding fiche N° 27.
•Computer configuration depending on gearbox type (manual gearbox or automatic transmission).
FITTING A 2ND GENERATION ENGINE IMMOBILISER REQUIRES A SPECIAL PROCEDURE FOR REPLACING THE
COMPUTER.
