REMOVAL
Remove the air filter (two mounting bolts at the
top, two mounting nuts at the bottom (1)).
Remove, from above, the two nuts fixing the ex-
haust downpipe to the manifold.
Slacken, without removing it, the nut on the
clamp connecting the downpipe to the exhaust
pipe.
Tilt the exhaust downpipe towards the gearbox.
Remove the nuts securing the manifolds:
- nuts (A) from above,
- nuts (B) from below.

Special note
To remove nut (C) located above the starter mo-
tor, use a small ratchet (6.35 mm square) and a
universal joint.

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).

The screen will display :
COMPUTER CONFIGURATION DEPENDING ON GEARBOX TYPE (MANUAL GEARBOX OR AUTOMATIC
TRANSMISSION)
Each time the injection computer is replaced, it must be programmed with the type of gearbox (manual or
automatic) which is fitted in the vehicle. The computers are designed to function with either type of gearbox.
Method for configuring the computer
Connect the
XR25
Select S8
Switch on the ignition
Enter D13 then
For vehicles fitted with manual gearbox :
Enter G50* 2*
For vehicles fitted with automatic transmission :
Enter G50* 1*
if the configuration has not been made
To ensure that the computer has memorised the data correctly, switch the ignition back on , using fault fin-
ding fiche n° 27; the fault bargraph
20 LH should be extinguished, whilst the 19 LH or RH status bargraph
should be illuminated.
