On a static reading ( just turn on the ignition switch, do not start the engine ) and dynamic reading ( need to start the engine ) electronic control systems , attention should read both the order and the relevant code conversion process , otherwise it will cause reading the failure to take fault codes , reading many models of these two conversions have strict procedural requirements .
First, you must first read the static code (KOEO) , if the static code reading , the system does not output code “11” is the normal fault codes, reading dynamic yards to go (KOER) , it will fail distortion and cause miscarriage of justice overhaul . Then tend to give an illusion caused by maintenance personnel , as if the fault code useless like. Also, be careful in reading dynamic code before the general need to clear the static code . Dynamic code during self-diagnosis , you should remove the static code reading diagnostic socket when connected on a jumper , and then clear the static fault codes, then start the engine and accelerate to 2000r/min, keeping more than 2min to allow the engine to reach normal operating temperature , then turn off the ignition switch, and then wait for 10s after a good jumper from the diagnostic connector and start the engine again , this time shows the fault code is in dynamic mode fault code.
