Ignore this bargraph if the vehicle is not fitted with an immobiliser.NOTES
Connect the bornier in place of the computer and check the insulation, continuity and that there is no
interference resistance on the wiring on track 37 of the computer.
Repair if necessary.
If the fault persists, refer to the immobiliser fault finding.

Check the insulation and continuity of the wiring:
Fuel pump relay L5 Impact sensor
Impact sensor C1 Fuel pump
Repair if necessary.
Check the 30A fuel pump fuse.
Check the insulation and continuity of the wiring:
Fuel pump fuse L3 Fuel pump relay

FUEL PUMP
XR25 aid:The command mode should cause the fuel pump to operate
No fault bargraphs should be illuminated.NOTES
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.

35 tracks
If the information obtained by the XR25 requires electrical continuities to be checked, connect bornier MS
1048.
Bornier MS 1048 is a 35 track base with a printed circuit on which are 35 copper coated surfaces, numbered
from 1 to 35.
Using the wiring diagrams, the tracks connecting the components to be tested can be easily identified.
IMPORTANT :
• All tests using bornier MS 1048 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.
