This test can only be carried out using a lead testing kit supplied by NAUDER.
To obtain a testing kit, contact your local After Sales Head Office.
Part numbers : - Complete kit : T900
- 40 test papers : T900/1
ANTIPOLLUTION
Test for the presence of lead
14
METHOD
a - Test conditions :
- Engine stationary.
- Exhaust pipes warm.
- Do not test when the temperature is below 0°C.
b- If necessary use a soft cloth to clean the inside of the exhaust pipe so any soot deposits are removed.
c- Wearing the gloves, take a test paper and moisten it slightly with distilled water (the paper is not
effective if it is too wet).
d- Press the damp paper onto the cleaned exhaust pipe immediately and hold it there firmly for about a
minute.
e- Remove the test paper and allow to dry. The test paper will turn red or pink if lead is present.
IMPORTANT: The test for lead should only be carried out on the exhaust pipe, never on the oxygen
sensor.

Alternator

OPERATION - FAULT FINDING
These vehicles are equipped with alternators with
internal ventilation and integral regulator, also
with a warning light on the instrument panel
which has the following functions :
- when the ignition is switched on, the light illu-
minates
- when the engine is started the light extin-
guishes,
- if the light illuminates whilst the engine is
running there is a "charging "fault.
LOOKING FOR FAULTS
The warning light does not illuminate when the
ignition is switched on.
Check:
- all electrical connections are good.
- the bulb has not blown. (Earth the circuit and
the bulb should illuminate).
The warning light illuminates when the engine is
running.
This indicates a charging fault which could be
caused by :
- the alternator drive belt being broken or the
charging wiring being cut,
- internal alternator damage (rotor, stator,
diodes or brush),
- a regulator fault,
- excess voltage.The customer complains of a lack of charge and
the warning light is operating correctly.
If the regulated voltage is less than 13.5 V, check
the alternator. The fault could be caused by :
- a diode which has been damaged,
- a phase which is cut,
- contaminated or worn tracks.
Checking the voltage
Connect a voltmeter across the battery terminals
and read the battery voltage.
Start the engine and increase the engine speed
until the needle registers a stable regulated
voltage.
This voltage should be between 13.5 V and 14.8 V.
Connect as many consumers as possible, the
regulated voltage should be between 13.5 V and
14.8 V.
IMPORTANT: if arc welding work is to be carried
out on the vehicle, the battery and regulator
must be disconnected.

STARTING - CHARGING
Starter motor

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.

Injection fault warning light
17
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.

Immobiliser function
17
This vehicle is fitted with a 2nd generation immobiliser system.
REPLACING THE INJECTION COMPUTER
All 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 a check must be made to
ensure that the immobiliser system is operational.
To do this, it is sufficient to carry out the following operations:
- turn the ignition on for a few seconds and turn it off again,
- remove the key to guarantee the immobiliser function.
CHECKING THE IMMOBILISER FUNCTION
Remove the key from the ignition switch. After 10 seconds the red immobiliser warning light will flash.
For special notes on testing an injection computer (test part), refer to section 82: "Immobiliser".

INJECTION
Richness regulation
17
Non-loop mode
When richness regulation is occurring, the operating phases when the computer ignores the voltage informa-
tion from the oxygen sensor are:
- Full load: #35 = variable and greater than 128
- Sharp acceleration: #35 = variable and greater than 128
- Deceleration with no load information (injection cut) : #35 = 128
- Oxygen sensor fault: #35 = 128
DEFECT MODE IN THE EVENT OF AN OXYGEN SENSOR FAULT
If the voltage from the oxygen sensor is incorrect (# 05 varies only slightly or not at all) during richness regu-
lation, the computer will only enter defect mode (# 35 = 128) if the fault has been present for 3 to 5 minutes.
The fault will be memorised in this case only.
If an oxygen sensor fault is present and recognised and if the fault has already been stored, the system enters
the open loop mode directly (# 35 = 128)
