1 Answers
Solution for the U0100 trouble code: The U0100 trouble code indicates a loss of communication with the Engine Control Module (ECM) or Powertrain Control Module A. In such cases, it is necessary to check whether the power supply to the engine control unit is normal. Generally, this issue is caused by an abnormal power supply to the engine control unit. It is recommended to conduct a detailed inspection at a repair shop before proceeding with troubleshooting. The vehicle's engine control module monitors information from various sensors and other input signals, controlling systems that affect vehicle performance and emissions. The engine control module also performs diagnostic tests on various system components, identifies operational faults, and reports them to the driver via the malfunction indicator lamp. When a fault is detected, the engine control module stores the trouble code, and the fault location is identified by the specific trouble code set, which aids technicians in performing repairs.
