OPTIMA 5800 diagnostic station
CHECKING THE STARTER USING THE DIAGNOSTIC STATION
The starter may be tested using the OPTIMA 5800 diagnostic station, by measuring the battery voltage and
the current used during the starting phase. The following operating faults may be detected:
- battery fault (voltage drops when the starter is activated),
- starter jammed (the current used is too high),
- starter fault (the current used is too low).
To carry out the test the vehicle must be prevented from starting:
- E7J, K7M engines : disconnect the engine speed sensor (on the clutch bellhousing),
- F3R engines : disconnect the engine speed sensor (on the gearbox),
- F8Q engines : disconnect the fuel shut off on the pump and insulate the terminal.
NOTE :
- an open circuit on the engine speed sensor or the ignition creates a fault which is memorised in the injec-
tion computer. Erase this fault using the XR25 (see injection section),
- if the vehicle is fitted with an immobiliser, just lock the doors using the PLIP.

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.
