It is necessary to use a decoder to decode and identify the fault, then visit a professional repair shop for inspection and maintenance. More information about Auman is as follows: 1. Brand Introduction: The Auman brand ("AUTO-MAN") also expresses the brand characteristics of "quality, technology, intelligence, and comfort" through its name connotation. On February 18, 2012, Beijing Foton Daimler Automobile Co., Ltd. was officially established. The joint venture will inject advanced technology and management into the Auman brand, further enhancing its competitiveness through full value chain upgrades and promoting the transformation of China's heavy-duty truck industry from large to strong. 2. Advantages of Auman: Auman integrates global resources and comprehensively adopts imported components for key parts and assemblies. For example, it uses globally recognized German VABCO valves, Siemens tachographs, electronic instruments, etc. This shows that the overall performance of Auman vehicles is a product that integrates the wisdom of global automotive giants. Additionally, with the overall optimization of the Auman chassis system by experts from Lotus UK and Mercedes-Benz, Auman heavy-duty trucks were able to compete on the same track as international heavy-duty truck giants like Mercedes-Benz and MAN at the famous Hockenheim F1 circuit in Germany. Subsequently, it became the first Chinese vehicle to be collected by the renowned Speyer Technology Museum in Germany, achieving such proud honors. This significantly improves the reliability of the entire vehicle. At the same time, the implementation of Toyota's TPS production management method has established a strict quality control system, steadily improving product quality.
I encountered a similar issue last time. On the Auman truck, fault code 1746—9 usually indicates a sensor or control system problem. It could be an oil pressure sensor failure causing abnormal engine performance and a surge in fuel consumption, or a malfunctioning transmission control module leading to poor shifting. Truck drivers, please note: when the dashboard warning light comes on, don’t rush to hit the road. First, use a simple OBD tool to scan for specific error codes to check if it’s caused by loose or water-damaged wiring connections. Older trucks especially need to be checked for cracked insulation due to aging wiring—address it promptly to avoid short circuits. For routine maintenance, remember to regularly clean dust and keep sensors dry. Otherwise, a sudden breakdown on the highway is too dangerous. Experience tells me repairs aren’t cheap either—replacing a new module can cost thousands.
As an Auman truck owner, I encountered the 1746-9 fault last year, which turned out to be caused by low fuel pump pressure triggering a chain reaction. The truck lacked acceleration power and frequently stalled, seriously affecting cargo delivery schedules. Initially, I thought it was a minor issue and delayed repairs, only to find the transmission system suffered more severe damage later, leading to significantly higher costs. My advice is to first check whether fuses and relays are burnt out – sometimes simply replacing these components can solve the problem. Alternatively, inspect the fuel system for any signs of blockage or leakage. Always pay attention to dashboard warnings and never overlook minor details – safe driving should be the priority. My fleet mates all say there's a huge difference between early and delayed repairs – don't lose big by neglecting small issues and delay transportation work.
