What does abnormal post-processing wiring harness in Foton Daimler mean?
3 Answers
Abnormal post-processing wiring harness in Foton Daimler refers to issues such as poor contact or problems with the wires, such as open circuits or grounding. Reasons for the abnormality: Natural damage to the wiring harness during use may occur due to prolonged product usage, leading to aging of the entire wire and cracking of the insulation layer. This reduces the overall mechanical strength performance of the product. Consequences: Reduced mechanical strength of the wiring harness can easily lead to open circuits and short circuits between wires. This can directly cause the wiring harness to burn out, and the product's terminals may oxidize and deform, resulting in poor contact and causing the equipment to malfunction.
Post-processing wiring harness abnormality in our Foton Daimler vehicles refers to a malfunction in the wiring harness of the exhaust post-treatment system (such as SCR or DPF), leading to various issues. Specifically, this wiring harness connects sensors and actuators, responsible for controlling emissions. If there's a short circuit, open circuit, or issues like loose or corroded connectors, the system may report false alarms or fail. Common symptoms include the illumination of warning lights on the dashboard, potential loss of vehicle power, increased fuel consumption, and even impacts on exhaust emission standards. During repairs, diagnostic tools are used to check fault codes, identify the problem points, and replace or reinforce the wiring. This issue is critical for driving safety and environmental protection. If not addressed promptly, the vehicle may break down unexpectedly, causing significant trouble. Therefore, it's recommended to visit a 4S shop or professional repair center immediately upon detecting any abnormality. Regular maintenance should also include thorough checks of engine compartment wiring to prevent corrosion.
I've driven Foton Daimler trucks and encountered this kind of post-processing wiring harness abnormality. Simply put, it's an issue with the wiring of the exhaust aftertreatment system – could be loose connectors, broken wires, or corrosion causing signal interference. At the time, the emission warning light kept flashing, the truck felt underpowered, and I was worried about getting fined for excessive emissions. The mechanic said it's a common minor issue with Foton trucks – not difficult to fix, just replace the harness or clean the connectors, but don't delay repairs as it affects driving safety. The lesson I learned is to regularly inspect engine wiring, keep it dry, and anti-corrosion spray works wonders. Repair costs are usually low, but safety comes first.
