1997 RENAULT KANGOO fuel pump

This bargraph only illuminates when the computer feed has been cut (disconnection of the battery, the
computer, ...).
Check the computer feed hygiene:
Computer 1 5 Main relay

Repair if necessary.
Run the engine.
Switch the ignition off and wait for the loss of dialogue between the XR25 and the computer.
Switch the ignition on.
Enter dialogue with the computer.
Erase the computer memory using G0**.
NOTE :Memorised faults are erased. It would therefore be useful to carry out a road test to check
there are no faults on the injection system.

Ensure the canister bleed valve is sealed.
Erase the computer memory.
Engine warm , running at idle speed, check the values for # 30 and # 31.
-If # 30 or # 31 is at a MAXIMUM, there is not enough fuel.
- If # 30 or # 31 is at a MINIMUM, there is too much fuel.
