The hardware composition and software testing principle of ODISSEE communication equipment for ABS anti-lock braking system of car are studied. According to the function test requirement of ABS, ABS initialization test and ABS start test, ABS static test, ABS dynamic test, ABS stop test, ABS write process, ABS result test, WSS wheel speed sensor test, etc are carried out in turn. According to the value of ABS dynamic test, the braking force of the four wheels is calculated to meet the requirements of the regulations; the operator interface during the testing process shows the test steps, the operation of the test requirements and the test results in time, which is convenient for the operator to operate the test. This paper can be used as reference for equipment maintenance technicians and automobile testing technicians.
