Only consult this customer complaint after a complete check using the XR25.
Measure the resistance of the altimetric corrector at the 10 track pump connector (between tracks 1 and
6).
Replace the altimetric corrector if the resistance is not approximately 15 ohms.
Ensure the continuity of the connection between track 1 on the pump connector, wiring side, and track 5
on the altimetric connector control relay (position H on the relay plate in the engine connection unit).
Ensure the presence of earth on track 6 of the pump connector, wiring side.

If the information obtained by the XR25 requires electrical continuities to be checked, connect bornier Sus.
1228.
Bornier Sus. 1228 is a 55 track base with a printed circuit on which are 55 copper coated surfaces, numbered
from 1 to 55.
Using the wiring diagrams, the tracks connecting the components to be tested can be easily identified.
IMPORTANT :
• All tests using bornier Sus. 1228 must be carried out with the battery disconnected.
• The bornier is only designed to operate with an ohmmeter. Under no circumstances should 12 Volts be
applied to the test points.

Check the hygiene and presence of earth on track C2 of the fuel pump.
If + 12 V is not reaching the fuel pump, replace the fuel pump relay.
If + 12 V is reaching the fuel pump, replace the fuel pump.
Check the impact sensor is correctly clipped in.

The pinking sensor should give a signal which is variable and not zero, to prove that it is recording the
mechanical vibrations of the engine.
If the signal is zero:
- Check the sensor is correctly screwed in.
- Check the insulation and continuity of the wiring:
Computer 8 2 Pinking sensor
Computer 44 1 Pinking sensor
Computer 2 Pinking sensor screening
If necessary, replace the sensor.
