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.

INJECTION
Injection fault warning light

PRINCIPLE FOR ILLUMINATION OF THE INJECTION FAULT WARNING LIGHT ON THE INSTRUMENT PANEL
• Vehicle without engine immobiliser system
When the ignition is turned on, the warning light illuminates for 3 seconds then extinguishes.
• Vehicle with engine immobiliser system deactivated
When the ignition is turned on, the warning light illuminates for 3 seconds then extinguishes.
When the doors are unlocked, the red immobiliser warning light, which was previously flashing, extin-
guishes. When the ignition is turned on, it illuminates for 3 seconds then extinguishes.
• Vehicle with engine immobiliser system activated
When the ignition is turned on, the computer does not identify the code and the vehicle cannot be star-
ted. The injection warning light illuminates for 3 seconds then extinguishes.
Before the ignition is turned on, the red immobiliser warning light flashes. When the ignition is turned
on, this light flashes twice as fast.
If a fault in the immobiliser system is detected when the engine is running, the injection warning light
will flash in the engine speed range from idle speed to 1 500 rpm approximately.
• Fault with an injection system component
Faults in the following components cause the warning light to illuminate:
- absolute pressure sensor,
- throttle position potentiometer,
- injectors,
- idle speed regulation stepping motor (K7M engine),
- idle speed regulation valve (F3R engine),
- no vehicle speed information when the vehicle is moving,
- EGR solenoid valve (K7M 703 engine),
- automatic transmission computer → injection computer (F3R - K7M engines).

This vehicle is fitted with a 2nd generation engine immobiliser system.
REPLACING THE INJECTION COMPUTER
The computers are supplied uncoded but are capable of being programmed with a code.
When replacing the computer, the vehicle code must be programmed in and then check that the immobiliser
system is operational.
To do this, carry out the following operations:
•Vehicle fitted with a PLIP engine immobiliser system
- Lock and unlock the doors using the PLIP.
- Turn the ignition on for a few seconds.
- Lock the doors using the PLIP, the immobiliser function is operational.
•Vehicle fitted with a coded key engine immobiliser system
Turn the ignition on for a few seconds then turn it off again.
CHECKING THE IMMOBILISER FUNCTION
•Vehicle fitted with a PLIP engine immobiliser system
- Turn the ignition off, lock the doors from inside the vehicle using the PLIP. The red immobiliser
warning light should flash.
- Turn the ignition on, The red immobiliser warning light should flash twice as fast.
•Vehicle fitted with a coded key engine immobiliser system
Remove the key from the ignition switch, after 10 seconds the red immobiliser warning light should flash.
TESTING AN UNCODED INJECTION COMPUTER FROM STOCK OR FROM A VEHICLE NOT FITTED WITH AN
IMMOBILISER SYSTEM
To avoid coding the injection computer before the test, it is vital to cut the + 12 V before ignition feed to the
immobiliser system. Remove the passenger compartment connection unit fuse (F39) (for more details, refer
to section 82).
NOTE : if the injection computer has been coded by mistake, a method exists for decoding it (refer to section
82).
SPECIAL NOTES
Using the XR25 it is possible to see if the injection computer is coded. The computer is uncoded if bargraph 2
right hand side is illuminated and if *22 = 2 DEF
A CODED COMPUTER FITTED TO A VEHICLE WITH AN ENGINE IMMOBILISER MAY NOT BE USED FOR TESTING
ANOTHER VEHICLE, REGARDLESS OF WHETHER THIS VEHICLE HAS AN ENGINE IMMOBILISER OR NOT.

Close and lock the hood.
Tighten the main bearing mounting bolts (3) to a
torque of 20 N.m.
Fold the hood.
Position the rear roof arch ram, secure it to the
clamp (6) and the pin (5) (electrohydraulic mecha-
nism).
Place the hood in the neutral position, rear roof
arch vertical.
Connect the hood microswitch wiring.
Fit the main ram and clamp it.
Position the connecting crossmember and tighten
the mounting bolts to a torque of 20 N.m.
Tighten the hydraulic unit bolt and operate the
electrohydraulic system several times (opening -
closing) in order to bleed the hydraulic circuit
(automatic bleeding).
