SOURCE: check engine light on daytime driving light indicator flashing
hi..
first of all it means that u have a problem some where on the suv the only way to find the problem is to hook a diagnostic computer and see what the code is u will have to take the car to a shop who works on isuzu and im sure they can tell u what code it is and whats wrong or u can take the suv to advance auto parts and they can hook there machine to it for free and tell u the code good luck
OK, the best action now would be to scan the ecu for any trouble codes that may be stored at this point with a diagnostic computer. this action will describe the issue concerning the check engine light and, it will also direct you to the location of the failed sensor that may be damaged at this time.
In most cases, this light will illuminate if a vital sensor has failed to register a signal for a short time or, if the sensor circuit is open.
thank u

If your check engine light is on then it means that there are codes stored in the computer. The easiest way to find out what they are is to go to an Advance Auto Parts Store or Autozone as I know they will read the codes and tell you what they are for free. If you do not have one of those stores around you I would suggest finding any auto parts store that offers a free diagnostic check. Once you know the code then you will be able to fix the problem. I am not sure why the S1 light is coming on but I do know that the first step to fixing your problem will be to get the codes read. otherwise you will just keep guessing. Hope this helps.
