LOCATION-REMOVAL OF COMPONENTS
CANISTER BLEED SOLENOID VALVE
(1)
E7J Engine
It is mounted above the inlet manifold,
underneath the cover
D7F Engine
It is mounted at the front, on the lifting bracket.

REMOVAL OF THE FUEL VAPOUR ABSORBER (1)
This is located in the front right hand wheel arch.
REMOVAL
Disconnect the pipe connecting the canister to the
inlet manifold, from the top of the vehicle.
From the bottom, remove the wheel arch .
Disconnect the pipe at (2) connecting the
canister to the fuel tank.
Remove the three bolts at (3) mounting the
canister (1) then extract it.

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.

REMOVAL
Place the vehicle on a two post lift.
Remove :
- the battery,
- the injection computer mounting, after ha-
ving disconnected the 55 track connector as
well as the impact switch connector,
13088S
- the mounting (1) for the power assisted stee-
ring pipe, along with the strut at (A),
13336-1R
- the front right hand wheel ,
- the driveshaft pin using punches B. Vi. 31-01,
- the upper shock absorber bolt and slacken the
lower bolt.
Tilt the hub and release the driveshaft assembly
from the gearbox.
Remove the starter connections , as well as the
mounting bolts and extract these from the bot-
tom of the vehicle.
REFITTING
Refitting is the reverse of removal.
Check for the presence of the centring dowel
which should be located at (B).
