1. What is the performance of unplugging the fuel metering unit? All the fuel enters the common rail pipe, causing the rail pressure to be too high, the pressure limiting valve opens, and the limp mode is entered. It is also easy to cause the oil temperature to rise, which is detrimental to the entire…

Some failures will inevitably occur when the equipment is used for a long time. After investigation, it is found that there are three main types of failures: circuit failure, mechanical failure and external interference. 1. Circuit failure When the power is turned on, the ABS indicator light should be on, and once the vehicle speed…
