re-start car 3 times in 90 secs
The car needs to go on to diagnostic equipment for the codes to be read, the fault needs to be diagnosed and remedial action taken the codes can then be cleared & the warning light can then be reset.
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.
First the light has to be connected to a tester to erase the fault codes. Then it should be programmed to get the new codes and it works.
The ABS light is on because there is a fault in the system. Once the fault is repaired or fixed the light will reset itself. The ABS system can be scanned for codes to help diagnose the problem.
There is no reset for the computer. You can disconnect the negative battery cable for 5 minutes and this may or may not reset any fault codes. If not they will have to be reset with an OBD2 scan tool.
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).
No. If you car is having difficulty requiring reset, disconnect the battery overnight or for several hours. This will reset the computer and clear any codes that may cause the computer to prevent the ignition from operating. There are a couple of ignition codes that will prevent the car from starting.
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.
Repair the component that set the fault code, and then reset the ECU with an OBD2 scan tool.
I believe you can unhook the battery and let it sit for about 5 minutes before hooking it back up. Otherwise you need a VAGscanner to reset the fault codes.
you will need to plug in an obd diagnostic scanner to read the fault codes then clear them which will turn off the light
use the consult-II with the NATS card to erase the codes. have your keys reprogrammed too.
