What is the solution for OBD faults in Auman trucks?

Auman OBD fault resolution involves reading the fault codes for troubleshooting. The OBD system connects various emission-related component information to the Electronic Control Unit (ECU), which possesses the capability to detect and analyze faults related to emissions. When an emission fault occurs, the ECU records the fault information and corresponding codes. By reading these fault codes, the nature and location of the fault can be quickly and accurately identified. Taking the Auman EST as an example, it features a red body color scheme, with exterior design inspired by European and American super trucks. It boasts a horizontally arranged three-layer honeycomb mesh grille, standard LED daytime running lights, split rearview mirrors equipped with blind-spot assist mirrors, giving the front fascia a strong technological appeal and high recognizability.
When the OBD light in my Auman truck comes on, I usually first check the dashboard to see if there are any other warning lights, such as the engine or emission system. Then, I locate the OBD scanner and plug it into the diagnostic port of the vehicle, typically found under the steering wheel. After the scanner reads the fault code, I look up the meaning of the code online. For example, P0300 indicates an engine misfire, possibly due to spark plug issues. Next, I try to clear the fault code to see if the light was a false alarm. If the light remains on or there are driving issues, I check the related sensor connectors for looseness or dirt. However, when it comes to the engine, I generally avoid repairing it myself to prevent causing damage and instead take it to a nearby repair shop for professional inspection and handling. During regular maintenance, I remind the shop to test the system to minimize potential issues.
My habit is not to rush driving when an OBD fault appears—safety first, as it can easily affect braking or acceleration. I take out an inexpensive diagnostic tool, connect it to read the fault code, and note its meaning—for example, P0420 indicates a catalytic converter issue, which could be a sensor fault or an exhaust leak. The next step is to disconnect and restart the vehicle to try clearing the code. If the light goes off, it might be fine temporarily, but I still check the relevant wiring for aging or damage, using a multimeter to test voltage if necessary. For complex issues involving control modules, I recommend visiting a reliable 4S shop without delay to avoid major repairs later. Before driving, ensure the dashboard warning disappears to prevent mid-journey mishaps that could threaten safety.
Auman's OBD system is similar to other vehicles where you can use a Bluetooth code reader to connect with a mobile app to check faults. Usually, I share common codes in the car enthusiast circle, such as P0171 indicating a lean air-fuel ratio, which might be due to an intake pipe leak or a dirty oxygen sensor. I typically clean the connectors first; if that doesn’t work, then I go to the shop for a deeper computer diagnosis. Preventing minor issues from turning into major repairs is key—don’t skimp on these inspection costs.
