OPTIMA 5800 Diagnostic station
CHECKING THE STARTER MOTOR USING THE DIAGNOSTIC STATION
Checking of the starter motor is carried out using the OPTIMA 5800, by measuring the battery voltage and
the current absorbed in the engine starting phase. The following operation faults may be highlighted :
- a fault in the battery ( the voltage falls during the starting phase),
- locking of the starter motor (the current absorbed is too high),
- a fault in the engine starter gear (the current absorbed is too low).
In order to carry out the measurement, it is necessary to stop the vehicle from starting :
- for D7F and E7J engines : disconnect the engine speed sensor (located on the clutch housing ,
- for
F8Q engines : disconnect the pump electrical solenoid and isolate the terminal.
NOTE :
- an open circuit on the engine speed sensor or the ignition creates a fault memorised by the injection
computer, this fault must then be erased from the memory using the
XR25 (see "Injection" section),
- if the engine is fitted with an immobiliser, it is sufficient to lock the doors using the remote control.

PRESENTATION
The system comprises:
- the injection computer (the ignition power
stage is integrated into the computer),
- two dual output coils, (for the
D7F engine,
these are moulded into one),
- four spark plugs,
- an anti-interference condenser (4).
DESCRIPTION - OPERATING PRINCIPLE
COMPUTER
The injection computer (120), depending on the
information received from various sensors, but
principally depending on the engine speed and
load, determines:
- the number of degrees of advance to be used
and consequently the ignition point,
- which cylinders are at TDC and consequently
the ignition coil to be operated.
The spark is created at the two cylinders at TDC by
cutting the earth to the coil concerned.
COILS (1)
There are two coils. They are of the dual output
type (they cannot be separated in the
D7F en-
gine ).
They are controlled separately by the computer.
They create two sparks simultaneously.
Both coils are connected to an anti-interference
condenser.

Special features of the E7J engine
The coil at (2) has a black electrical connector. It
creates a spark simultaneously at cylinders 1 and
4. It is controlled by track 28 of the injection
computer.
The coil at (3) has a grey electrical connector . It
creates a spark simultaneously at cylinders 2 and
3. It is controlled by track 29 of the injection
computer.

Coolant temperature management
244Injection coolant temperature sensor and
coolant temperature indication on
instrument panel.
3 track sensor, of which two tracks are
allocated to the injection coolant
temperature information, and one to the
indication of the coolant temperature on
the instrument panel.
259Warning coolant temperature switch for
instrument panel.
Operating principle
Sensor 244 allows :
- the coolant temperature to be shown on the
instrument panel,
- the injection computer to receive constant in-
formation on the engine coolant temperature
.
The injection computer, depending on the co-
olant temperature, controls :
- the injection system,
- the cooling fan assembly.
The engine cooling fan assembly is controlled
at fast speed (both slow and fast speeds are
controlled by the air conditioning system) if
the temperature is greater than 99°C. If the
temperature falls below 96°C, it cuts off
automatically ( if a check has to be carried out,
ensure that the air conditioning is not opera-
tional).

Injection fault warning light

PRINCIPLE FOR ILLUMINATION OF INJECTION FAULT WARNING LIGHT ON INSTRUMENT PANEL
• Vehicles not equipped with the immobiliser function:
When the ignition is switched on, the warning light illuminates constantly for 3 seconds , then extin-
guishes.
• Vehicles with immobiliser function deactivated:
When the ignition is switched on, the injection warning light illuminates constantly for 3 seconds and
then extinguishes.
When the doors are unlocked, the red immobiliser light, which was previously flashing, extin-
guishes.When ignition is switched on, it illuminates for 3 seconds , then extinguishes.
• Vehicles with immobiliser function activated:
When the ignition is switched on, the computer does not recognise the code, and stops the engine from
starting. The injection warning light remains illuminated for 3 seconds and then extinguishes.
Before the ignition is switched on, the red immobiliser light flashes. On switching the ignition on, it
flashes more rapidly.
If a fault is detected in the immobiliser system whilst the engine is running, the injection warning light
flashes in the engine speed range between idle speed and 1 500 rpm approximately .
• Fault in a component of the injection system
The warning light is illuminated if a fault has been detected in:
- the pressure sensor,
- the vehicle speed,
- the throttle potentiometer,
- the idle speed regulation stepping motor.
