I have a Renault Kangoo 2006 1.9D with a problem on the board. It is this board: When it works, everything works fine, all watches, lights, backlight, lcd with mileage. But it happens that after stopping it working well, I go back to the time, I put in contact and on the board only the lights of the middle light, no clock works, neither the lcd of the right, nor the back light that lights everything to the arrest the position lights. Check fuses, all are OK, the battery is almost new and charge to full. I passed the scanner and it does not throw any DTC error, with the scanner of renault (can clip), it throws some faults but they are all related to the fuel, by a pump change that was made and nullified sensors. I find that if I disconnect the large gray connector behind the board, and reconnect it, when I put it back in contact it works again for a while, until the fault returns. This disconnect and reconnect only fixes the fault if the key is not in contact. With the fault already occurred, the key in contact, disconnect and reconnect does not change anything. Moving the contact a little to see if there is any false contact does nothing, just disconnect and reconnect works. That could be happening?

Look behind the board if there is not a diode, control it, most likely the diode is short-circuited.
