"Check" light goes on for OBC fault codes ie- tailights out, brakes light bulbs out,etc..

"Check engine" light is for OBD fault codes ie- O2 sensor, Maf sensor, etc.. car 95 and older you can retrieve these codes with the gas pedal method. 96 and newer cars have to be read with a code reader to find out the problem

ive tried the gas pedal method a million times and have never got it to work, is it cause my obc is constantly flashing brake light circuit?

Check engine = somehting wrong with your engine, use an obd2 scan to see what is wrong.

Check control = something elese is wrong, hit the "check" button and it will tell you what's wrong.

To access the codes on my car I have to pump the gas pedal very quickly. Try doing it as fast as you can..

thanx 93 325i...
this might sound stupid, but what does hitting the gas pedal do? where do i see the codes? do i have to get a code reader and plug it somewhere? perhaps in the hood where the oil reset light is?

thanx

If your car is a 95 or older hitting the gas pedal 5 times initiates the fault code sequence. Turn the ignition key to "on" but not starting the car(it's the notch just before starting your car). Hit the pedal 5 times quickly and the "Check Enigine" will start a series of flashes. Record these flashes: Example
Flash(pause), Flash Flash(pause), Flash Flash(pause), Flash(pause)
1 - 2 - 2 - 1

According to the chart- code 1221=Oxygen Sensor #1 might be faulty

If your car is 96 and newer you have to buy a scan tool or have it read by a mechanic to find out what's wrong..

thanx again...
if my car is behaving properly (meaning no check engine light or obc lights are on when i m driving), should i still do this check? or will i end up worrying myself over nothing by doing this? i was thinking about doing this as a preventive measure... what are yer thoughts?

your welcome...I wouldn't worry about it then. You can try it out just because and it should flash out 1-4-4-4 (no more faults) if there currently is no check engine light on.
