D Calibration checking plate
Principle
The sensor, through the adjusting button (1), the
pressure device (2) and the outer lugs (3), applies a
constant force to the belt.
The reaction from the belt is measured using a
test piece (4) fitted with strain gauges.
Any movement on the gauges creates a variation
in their electrical resistance. This variation, once it
has been converted by the device, is displayed on
the display in SEEM units (US).Calibrating the device
The device is set in the factory, however it must be
recalibrated every six months.
Procedure
Resetting zero:
- switch the device on (button E) with the adjus-
ting button (1) fully screwed in,
- if 0 is displayed, do not touch anything,
- if nothing is displayed, check the condition of
the 9 volt battery in the device ,
- if a value other than 0 is displayed, adjust screw
(F) until 0 is displayed.

Checking the calibration
Switch the device on (button E).
Position the calibration spring plate (Z) on the sensor as shown on the diagram (checking value engraved to-
wards the top, (A) minimum value, (B) maximum value).
Tighten the adjusting button (1) until it goes "CLICK - CLICK - CLICK".
Check that a value X between the values (A and B) (A ≤ X ≤ B) is displayed.
Note: it may be necessary to perform several preliminary tests in order to obtain the correct value.
If the correct value if still not obtained after several attempts, contact SEEM.
NOTE : each device has its own calibration spring plate and they are not interchangeable.

GENERAL INSTRUCTIONS:
- Never refit a belt which has been removed, re-
place it.
- Never retighten a belt for which the tension
reading is between the fitting value and the
minimum operating value.
- When checking, if the tension is below the mi-
nimum operating value, replace the belt.

Engine cold (ambient temperature).
Fit the new belt.
Position the sensor of Mot. 1273.
Turn the adjusting button of the sensor until it disengages (three ’’CLICKS’’).
Tension the belt until the recommended fitting value is displayed on Mot. 1273 .
Lock the tensioner, check it, adjust the value.
Turn the crankshaft overthree times.
Check that the tension value is within the fitting tension tolerance, otherwise readjust it.
NOTE :
Never refit a belt which has been removed.
Replace the belt, if the tension is below the minimum operating tension.
Small cuts or cracks do not mean that the belt has to be replaced.

The display shows:
CONFIGURING THE COMPUTER DEPENDING ON GEARBOX TYPE (MANUAL OR AUTOMATIC)
Each time the injection computer is replaced, the gearbox type for the vehicle must be programmed (manual
or automatic). The computer is designed to operate with both these types of gearbox.
Procedure for configuring the computer:
Connect the XR25
ISO selector on S8
Turn the ignition on
Enter D13 then
For a vehicle fitted with a manual gearbox:
Enter G60*
For a vehicle fitted with an automatic transmission:
Enter G50*
If the configuration has not been programmed
After programming the configuration, turn the ignition off to store it in the memory. Memorisation is effec-
tive after the ignition has been turned off, once the computer has left the monitoring mode.
The monitoring mode varies from 30 seconds to 13 minutes.

FUEL TANK
Gauge
19
For petrol engines, the pump and gauge sender
unit are an inseparable assembly.
For diesel engines, there is no pump submerged in
the fuel tank, there is only a gauge sender unit.
For removing the gauge sender unit refer to the
section FUEL TANK "Pump - sender unit".
Checking the gauge sender unit
Ensure the resistance varies by moving the float.

Measuring the height H
With the gauge sender unit removed, place it on a
flat surface.
H is the height measured between the float pin
and the working surface.

Put the vehicle on a two post lift.
Lift the vehicle until the wheels are a few centime-
tres off the ground.
Connect the
XR25.
Put the
ISO switch on S8.
Enter the A4.2 transmission code :
D14
then #06 to display the engine speed.
Accelerate fully with the brake fully on.
The engine speed should stabilise to :
-K7M engine: 2430 rpm.
If this value is not correct, replace the converter.
A timing point which is more than 200 rpm. below
the specified value requires the automatic trans-
mission to be replaced.
NOTE : for all diagnostic questions, refer to MR
TA.A, "General".
