COMMANDPETROL TANK
SUGGESTIONS No defect should be present or memorized
Check that the shock sensor has the inner contact shut.
Push in order to perform the closing of the shock sensor, if necessary.
Check, while the injection calculator commands the petrol pump, the presence of 12V at
pin 3 of the shock sensor.
If there is no 12V at pin 3 of the sensor, then remedy the circuit between pin 3 of sensor
and pole 5 of petrol pump relay.
Check the continuity between pin 1 and pin 3 of shock sensor.
If necessary, replac e shock sensor.
Check the integrity of the cabling and the presence of mass at pin A1 of the connector on
the cap of the petrol tank.
Check the insulation and the continuity of the cabling along the supply circuit +12V:
-pin 1 shock sensor
♦ pin B1 pe trol tank connector.
Remedy if necessary.
If the incident persists, replace petrol pump.
AFTER REPAIR Perform again the conformity test

SUGGESTIONS
Check the insulation and the continuity of the cabling along the
circu it to pin 8 of calculator.
Remedy if necessary.
If the incident persists, check on the basis of the electrical schema:
- the supply of the ventilator (700) and of the GMV ventilator
- the connection to the mass of the GMV ventilator
- th e state of the GMV (700) relay
- the state of the fuse (321) located between the relay 700 and the
GMV ventilator
- the state of the GMV ventilator.
Remedy if necessary.

Remedy if necessary.
If the incident persists, check on the basis of the electrical schema:
-t he supply of the ventilator (234) and of the GMV ventilator
-t he connection to the mass of the GMV ventilator
-the state of the GMV (234) relay
-t he state of the GMV ventilator.
Remedy if necessary.

COOLING - EX HA U ST - FU EL TANK
IMPORTANT
Duri ng the interventions affecting t he
petrol tank and the fuel supply circuit one
must not smoke or bring incandescent
parts near the work-place.
The emptyi ng of the tank does not require
taki ng apart the tank. Ac ces s is allowed
through the inside of the car (i.e. the boot). To take apart:-the carpet of the boot;
-t he lid of the visiting mouth (by taking
off th e four screws);
-the c lick-collar 1 is ta ken out by means
of the MOT 1202 device;
-a t ube is adapted to the A outlet, which
should be long enough to be introduced into a
ve ssel outside the car. The
H relay of the petrol-pump is taken out of
the fuse box located in the engine compartment,
and term inals 3 and 5 of the re lay connector are
shunted, thus ensuring the operation of the petrol
pump ( 12 V).
Th e operation of the pump will be stopped
when an intermittent leakage of the petrol is no-
ticed. The shun t is taken off.
The relay is mounted.
