What does 'no communication with the ABS pump' in the CS75 mean?
2 Answers
No communication with the ABS pump in the CS75 may indicate that there is no current passing through the ABS pump. Check if there is a fault in the wiring. Below is an introduction to the ABS pump: 1. Content: ABS is an improved technology based on conventional braking systems, which can be divided into mechanical and electronic types. Modern vehicles are widely equipped with anti-lock braking systems (ABS), which not only provide the braking function of conventional systems but also prevent wheel lock-up. 2. Function: It ensures directional stability during braking, preventing skidding and deviation, making it the most advanced and effective braking device in vehicles today.
Recently, my CS75 also experienced an ABS pump communication failure. After troubleshooting, I found it's usually one of three common issues: either the pump connector is loose or the pins are oxidized causing poor contact, or the wiring from the control module to the ABS pump is broken. The worst-case scenario is the module itself failing. Remember to try disconnecting the car's power completely for ten minutes first—sometimes electronic systems act up and a power reset can fix it. If the issue appears suddenly after rain, it's likely due to waterlogged wiring or a short circuit in the connector. Last time at the repair shop, I saw the mechanic using a diagnostic tool to check the fault codes. If it shows a U-series communication fault code, it usually points to power supply, grounding, or CAN bus issues, and you'll need to test each circuit's voltage to pinpoint the problem.
