I built the homemade DTC tester on your web site, works good.
Can Iuse it to clear the codes in EA modules and LH modes?
Thanks again!  |
You say the battery voltage is "good". How did you test it???
You can reset the codes with HB reader by following the instructions in MENU#2 called "Erasing DTC Memory". You need to do this for each fault.
