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.

Idle speed correction

CONNECTION BETWEEN THE POWER ASSISTED STEERING PRESSOSTAT AND THE INJECTION COMPUTER
The injection computer receives information from the power assisted steering pressostat . This varies
depending on the pressure present in the hydraulic circuit. The higher the pressure, , the more energy is
absorbed by the power assisted steering pump.
To compensate for this energy absorption, the injection computer increases the opening ratio of the idle
speed regulation stepping motor.
The information is received on track 13 of the injection computer. If the pressostat is closed , the computer
receives an earth . The idle speed is adjusted to 800 rpm for the D7F engine and 850 rpm for the E7J
engine .
IDLE SPEED CORRECTION DEPENDING ON THE BATTERY VOLTAGE
The objective of this correction is to compensate for the drop in voltage, due to consumer operation when
the battery is poorly charged To correct this, the idle speed is increased, allowing the alternator to rotate
faster and consequently increase the charging voltage.
The lower the voltage, the greater the degree of correction. Correction of the engine speed is therefore
variable. It begins when the voltage drops to below 12.7 Volts. Correction begins at the nominal engine
speed and may reach a maximum of 880 rpm for the D7F engine and 930 rpm for the
E7J engine .
IDLE SPEED CORRECTION DEPENDING ON AIR CONDITIONING OPERATION
The injection computer increases the idle speed to 850 rpm. for the D7F engine and 880 rpm . for the E7J
engine , provided it receives the fast idle speed information from the air conditioning computer.
