Remove the fault codes in two ways;
First) Full warm up

- The MIL blinks continuously because the ECU memorized the fault code yet.
2. Full warm up the engine (keep idling five minutes)
3. Turn off the ignition key after full warm up the engine
4. Turn on the ignition key again, and check whether the fault code is disappeared or not.
After full warm up, it is possible to check the fault code is removed with the ignition key on/off.
If many problems happened in the EMS parts at the same time, only one defect code will is displayed
by the priority order.
Even thought repair a fault and remove the memorized fault code, another fault code blinks.
at this time, revise the fault and remove the memorized fault code by the warm up.
