What is the issue with fault code 65535?
2 Answers
Fault code 65535 indicates a malfunction in the electric power steering system, and replacing the electric power steering control module will resolve the issue. The Electric-Power-Steering (EPS) system is a power steering system that directly relies on an electric motor to provide auxiliary torque. Below are the reasons why a car's power steering failure may cause the steering wheel to become unresponsive: 1. Hydraulic power steering issue: Check if the power steering fluid is insufficient, ensure there are no oil leaks, and top up the fluid if it is below the normal range. If the fluid level is adequate, inspect whether the power pump belt is too loose; tighten the belt if necessary. Also, check if the oil is too dirty due to poor mobility, typically requiring replacement every 2 years or 60,000 kilometers. 2. Electronic power steering issue: Check if the fuse is blown and whether there are any open or short circuits in the wiring. 3. Tire pressure issue: A flat tire can also cause the steering to feel heavy or unresponsive, requiring inflation.
As an enthusiast who often helps friends with car repairs, I've encountered the 65535 trouble code several times. It generally indicates that the diagnostic tool cannot communicate with the vehicle's computer, possibly due to a loose interface, outdated scanner software, or ECU module failure. When dealing with it myself, I usually disconnect the battery for a few minutes and then restart, which sometimes resolves the issue. If the problem persists, I recommend checking if the OBD port has good contact or using a professional scanner to read the actual trouble code. In daily use, this code may cause the engine light to illuminate or affect the driving assistance system. The safest approach is to have it checked at a professional shop to prevent minor issues from escalating into major faults. Remember, timely action can save you more money and trouble.
