I have just got MD802 having used AL519 before. It was easy to get the code guide in AL519 by pressing [?]. How do I access the code guide in MD802. MD802 main feature description include "
OBD II code tips guide technicians to the root cause of trouble code faster".
I have the following P1135 on a Toyota "Air-Fuel Heater Circuit Response Malfunction" but when I press the [?] all I get is the help for using navigation keys.
AL519 would list possible causes or refer to service manual.
