Jl Mobile’s Computer Diagnostics Def, Forced Regens, & More

Owning and operating a semi truck comes with its fair share of challenges and responsibilities. One of the most important aspects of maintaining a semi truck is ensuring that it is in good working condition at all times. This is where computer diagnostics come into play.

Computer diagnostics is a crucial tool for semi repair shops when it comes to pinpointing and fixing issues with semi trucks. By using specialized software and equipment, technicians can quickly identify problems and perform the necessary repairs to get your truck back on the road in no time.

Semi Truck Diagnostic Computer: DEF Diagnostics 

One of the most common computer diagnostics that semi repair shops perform is DEF diagnostics. DEF, or diesel exhaust fluid, is an essential component for ensuring that semi trucks meet emission standards. If there are any issues with the DEF system, it can result in reduced fuel efficiency and even engine shutdown. By using computer diagnostics, technicians can quickly identify any issues with the DEF system and perform the necessary repairs to get your truck back on the road.

Forced Regens

Forced regens are another important aspect of computer diagnostics for semi trucks. A forced regen is a process where the technician uses specialized software to clean out the diesel particulate filter (DPF) in the exhaust system. Over time, the DPF can become clogged with soot and other debris, which can result in reduced engine performance and increased emissions. By performing a forced regen, technicians can ensure that the DPF is clean and functioning properly, which can help improve fuel efficiency and reduce emissions.

Other Simple Computer Diagnostics

In addition to DEF diagnostics and forced regens, semi repair shops can also perform a variety of other computer diagnostics for semi trucks. This includes checking the engine control module (ECM) for any error codes, performing a complete system scan to identify any other potential issues, and conducting a comprehensive inspection of the truck's electrical system.


By using computer diagnostics, technicians can quickly identify and fix any issues with your semi truck, saving you time and money in the long run. Instead of spending hours troubleshooting problems on your own or taking your truck to multiple repair shops, computer diagnostics can streamline the repair process and get your truck back on the road as quickly as possible.
