How do you reset the Renault clio engine warning light?

The engine management light is on for a reason. The car needs to have a diagnostics run on it and the fault corrected. Usually it will then reset itself and the fault will be recorded in the ECU memory. The codes can also be erased with the same diagnostics equipment but if the fault is not cured the light will come back on. Renault will usually put the car on there diagnostics for 1/2 on hours labour. You can then decide if you want them to repair it or find someone cheaper. Most local garages have diagnostics these days but not all can read the Renault codes.

How do you reset the codes on a 2001 peterbilt?

You get the software for the engine (e.g., DDEC for Detroit, Insite for Cummins, and I'm drawing a blank remembering what it is for Cat) and a diagnostic connector (such as NexIQ or Inline for Cummins), pull up the fault codes, and reset them. Now, if it's something which is going to be recurring, those codes will come back until you repair the fault (if they clear at all).

First repair whatever has caused the fault code. Then reset with an OBD 2 scan tool. Or you can simply remove the negative wire to the battery and that will erase the computer codes. If it's not fixed, it will return, usually by the 3rd or 4th time you turn the car on.
