Embodiment

[0058] 1. Specific implementation in the field environment: When the BCM body controller test is required, place the BCM body controller on the positioning mold, put the protruding part of the BCM body controller into the groove at the corresponding position, and pass the corresponding The positioning column precisely positions the BCM body controller, and then starts the air pump, which drives the cylinder, and the cylinder quickly clamps the BCM body controller to realize fast clamping during testing, and the test interface pins are completely inserted into the test points of the circuit board. Turn on the switching power supply, press the start detection button, and start the detection; if the LCD screen displays "detection complete", it means that the detection object has no fault; otherwise, it means that there is a fault, and the displayed faults correspond to the following tables 1 to 3, of which table 1 is the switch Meter, table 2 is the diagnosis circuit table, table ...

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and relates to a test system and a test method of a BCM vehicle body controller. Background technique [0002] With the extensive use of automobiles and the rapid development of the automobile industry, electronic control devices are increasingly used in modern automobiles. Body Controller Module (BCM) is a very important automotive electronic control device, which can provide central door lock controller, electric window controller, anti-theft alarm controller, lighting controller, airbag controller , wiper controller and many other electronic controllers output control signals to perform corresponding operations. Therefore, the test of BCM body controller before final assembly highlights its importance. [0003] At this stage, two testing methods are usually used: one is manual testing, and the other is bench testing. Manual testing means that product testing is carried out ...
