Off-line detection device and detection method of anti-lock brake system electronic control unit

The invention discloses an off-line detection device and an off-line detection method of an anti-lock brake system electronic control unit. The off-line detection device comprises a computer, an off-line detection software module which is arranged in the computer, an integrated function circuit board and a direct current voltage stabilizing power supply, wherein the function circuit board is connected with the detected anti-lock brake system electronic control unit and the computer through a control area network (CAN) bus and a K line; and the off-line detection software module is connected with the integrated function circuit board through a serial port. During off-line detection of different types of anti-lock brake system electronic control unit products, determination data of off-line detection software are modified, and novel off-line testing equipment is not required to be redeveloped. The invention has the advantages of high expandability, simple structure, high intuitiveness, high practicability, effective failure positioning capacity, high system traceability and the like. Product information is recorded, and unqualified electronic control unit products are effectively searched and traced.
