Analysis of DBC file

In the world of automotive electronics and industrial control, CAN bus is like an invisible neural network, which connects various control units (ECU) closely. The DBC file is the "language dictionary" of the network-it records what and how each node says, and understanding the DBC file is a necessary skill.   What is a DBC file DBC (Database CAN) is a CAN network data file, which...

Troubleshooting of CAN communication on OBC

Obviously, the vehicle has been connected to the charging gun, but the dashboard does not show the "charging" prompt, and the charging pile screen jumps out of a line of cold "communication failure" code. At that moment, a sense of anxiety came to my mind. Was the charging pile broken? Or was there something wrong with the car? After the maintenance engineer came to the door and tested it repea...

Insulation fault detection of EV

Vehicle reported insulation failure, limited power, unable to charge? Naked eye inspection can only judge the surface damage caused by moisture, and the accurate insulation resistance value must rely on professional insulation resistance tester. Use the insulation detector to complete the insulation detection of high-voltage circuit, understand the instrument, standardize the wiring, and fully ...

Why CAN resistance is 120Ω, but it is always inaccurate

Have you ever had the experience of confidently taking out a multimeter to verify whether the CAN bus is normal at the vehicle commissioning site, but the number popping up on the screen makes you confused-not the familiar 60Ω, but 140Ω, 180Ω, or even higher! You begin to suspect that the instrument is broken or that there is a problem with the wiring, but after repeated measurements, it is still ...

What Was That Golf Cart Thinking When It Backed Up on Its Own? — A Deep Dive into a Runaway Fault and the Fix

After a few years in the golf cart business, the phrase "unexpected runaway" is enough to put anyone on edge.Recently, one of our G1P two-seater carts gave us a real scare at an overseas partner's service bay. The vehicle was stationary, no one was touching the throttle, and yet—without warning—it suddenly sprang to life and backed up at full speed. The driver frantically moved the throttle lever,...
