Renault Clio Board Failure

Dear All.

Renault Clio 1.6 2005. Presents the following fault:
Board markers (motor temperature, rpm, speed, fuel level and lights do not work or do so intermittently. When the engine is maintained over 2000rpm it works again. It also feels that the engine fails, as for some coil.
It is reviewed:
The alternator, new battery, fuses, the connections look good, perform a test to the board and turn good. Pass scanner and everything ok. Investigating I know that the fuse that feeds the board is the same for Stop light. And this less work, only the 3 brake light.

Some idea.

You will not have a battery drama as it happens to the Peugeot?, I want to only that, but try the engine if it is k4m check the lands and I think that there is going

How Kikemec. The battery is new and the voltage is stable. Revizing the workshop manual, perform the dash and ground feed tests. They remain constant. According to the manufacturer if these are ok. The board must be replaced. He told me that it was with a multiplexed system and had to reprogram the board.
