wenn das check engine geht, dann sollte auch der sogenannte Stop Test gehen, und da kann man folgendes erfahren, ist EPA Vorschrift in USA:
Reading Engine Fault Codes
Fault codes can be read by turning the ignition key on and fully depressing the accelerator pedal to the floor five times in five seconds. The Check
Engine Light will then remain on for five seconds, blink off, come on for 2.5 seconds, then go off for 2.5 seconds. At this point, the fault codes
will begin to flash.
If more than one fault has been detected, each code will be separated by a 2.5 second pause. When all the fault codes have been displayed, there will
be a 0.5 second flash and then the light will remain off. To read the codes again, turn the ignition key off and then on again. Depress the accelerator
pedal to the floor five times quickly (within 5 seconds). The codes will begin to repeat.
To erase the fault code memory, first make sure that the fault code 1000 (short blink and light goes out for a long period) is present, then depress
the throttle fully for at least 10 seconds. Reactivate the fault code memory as described earlier and check for the 1444 code (no faults stored).
