REPLACING THE DAMPER VALVE
After replacing the damper valve, reconfigure the computer.
The system must be configured via the diagnostic socket using the RENAULT CLIP tool.
→ PROCEDURE to be followed after the damper valve is replaced:
–switch on the ignition,
–establish dialogue with the injection computer,
–run command SC036 Reset programming;
–select Damper valve as the operation type then follow the instructions given by the diagnostic tool,
–switch off the ignition,
–wait 1 min before switching on the ignition again,
–check that PR420 Damper valve error counter = 0;
–then check the system faults, and clear any stored faults;
–if there are faults, deal with the present faults,
–clear the faults from the computer memory.
Carry out a road test followed by a complete check with the diagnostic tool.
