pins

1 and 2 on the ISO7638 plug start to supply power to the ABS ECU and the electromagnetic valve, after power is supplied, the electromagnetic valve enters a self-checking exhaust process (exhaust or electromagnetic valve click, namely self-checking), meanwhile, the ECU energizes each ABS sensor to detect feedback voltage, and therefore whether open circuit or short circuit exists is determined. If the ECU does not find a fault after the self-test is finished, the fault indicator lamp is turned off after the self-test is finished.

If the fault exists, the judgment can be carried out in the following way: 1. the lamp has no self-checking sound, and the fault lamp is not lightened or is not extinguished after being lightened. And measuring the resistance value of the ABS electromagnetic valve, and determining the ECU problem if the resistance value is in a normal range. 2. And if the self-checking sound exists, the fault lamp is not extinguished after being lightened, and the ABS system is judged to have a fault. The ABS fault component can be displayed by flashing codes in a mode of an on-off detection switch. 3. The equipment tests that the ABS system is normal, but after the equipment is connected with the main car, the instrument lamp of the main car displays the ABS fault, the power supply or line connection problem of the main car can be judged, and the main car is detected.
