The code value ofthe "start code"is specifcally "0000" or"FFff", which is quite obvious. However, the code value ofthe "start code" on traditionaltwo-digit code diagnostic cards is uncetain and cannot be accurately identified by the human eye, you can referto the interet for more information.
Can test and diagnose faults of the test card itself: * It can fully support 286 to PlV high, medium and low-end motherboards, and the fault codes are more accurate and reliable, without causing systemcrashes. It has a function for repeatedly checking the codes, so the codes will no longer pass by quickly. When you press the switch once, it willdisplayone code and then pause.
