What does the U0113 fault code mean in Jiangling vehicles?

[IsaacRose]

U0113 fault code, applicable to all automobile manufacturers, means loss of communication with emission critical control information. Note: Whenever a vehicle fault is resolved, the fault code must be cleared. When performing code clearing, it is essential to strictly follow the specific fault code clearing procedure designated for the particular vehicle model. Under no circumstances should the method of disconnecting the negative battery terminal be used to clear the fault code casually. This may likely cause the following two types of problems: 1. Cause the control computer of certain vehicle models to lose 'experience memory'. As many are aware, the onboard computers of many vehicle models have automatic memory functions. If the negative battery terminal is disconnected carelessly, it will result in the loss of engine operation data stored in RAM. Consequently, the vehicle's performance may remain mediocre for an extended period after repairs, or previously cleared fault codes may reappear after some driving. 2. Sometimes it may also cause some useful functions to malfunction.

A friend told me that his Jiangling vehicle showed a U0113 fault code, which typically indicates a communication loss, specifically a disconnection between the CAN bus and the fuel cooler control module. In daily driving, this module manages engine cooling and fuel efficiency. A communication interruption could lead to sudden engine stalling or a sharp increase in fuel consumption. My old car had a similar issue before—the dashboard warning light came on, and the car struggled to accelerate. When diagnosing the problem, I found it could be due to loose wiring, a faulty module, or interference with the CAN bus. To address it, I recommend first using an OBD scanner to read the detailed error codes—don’t tinker blindly. Check for corroded cable connectors and ensure stable power supply. If the issue persists, take it to a repair shop immediately. Jiangling models often face such problems, and a professional can quickly diagnose it. Delaying repairs might damage the engine and make driving riskier, especially before long trips. Personally, I think checking wiring harnesses during regular maintenance is the easiest way to prevent small issues from becoming major headaches.

I found that the U0113 trouble code indicates a communication issue, particularly with the fuel cooler. It means the control module isn't communicating with the system, which can cause the vehicle to malfunction. For instance, recently while driving, I noticed strange engine noises and the emission light came on. I usually check the fuses and wiring connections first, as aging or wear can disrupt communication. Don't delay in addressing this—I recommend driving to a shop to scan the OBD code for confirmation. If the module is faulty, replace it. Jiangling vehicles are prone to this issue in winter due to low temperatures affecting the wiring. Paying extra attention during maintenance can help avoid it. Ignoring it long-term can increase fuel consumption and even lead to a breakdown on the road—safety first. Finding a reliable repair shop doesn't take much time and is much better than risking driving.

My Jiangling vehicle once displayed a U0113 fault code, which means communication loss, with the focus on the fuel cooler. This indicates that the modules can't communicate, potentially causing the car to shake or consume more fuel. When I encountered this issue, the warning light came on, and there was hesitation during acceleration. It's advisable to check the OBD codes immediately without delay. A simple check involves tightening any loose wiring connections; if that doesn't work, a professional repair shop visit is necessary. Addressing it early saves hassle.
