- 1. Symptom Reported by Customer The customer reports the constant appearance of the warning message "CHECK CHARGING SYSTEM" on the dashboard (tachometer) while driving the vehicle. 2. Technical Findings and Verification An inspection of the electrical and charging system was carried out: A full scan of the engine control modules (ECM) was performed, with no stored fault codes found. A lack of communication was confirmed between the vehicle's modules and the Battery Charge Monitoring Module. During the visual inspection, it was found that the harness connector plugging directly into the negative battery terminal was physically broken and disconnected. The 3-pin circuit was verified, confirming that the LIN communication lines, current, and return signal are functional and in good condition. 3. Root Cause of the Problem The direct cause of the "CHECK CHARGING SYSTEM" warning message is the physical disconnection of the Battery Management System (BMS) module. When disconnected, the vehicle control module cannot receive data about the battery's state of charge and health, activating the alert as a precaution. The physical damage to the connector (terminal) prevents communication within the vehicle's network. 4. Proposed Solution The recommended repair is to replace the BMS connector to restore physical integrity and communication within the vehicle network. Steps to follow: Replace and secure the new BMS connector onto the battery terminal. Verify that correct communication is restored between the vehicle modules. Clear the dashboard warning and perform a test drive to confirm that the system functions correctly and the message does not reappear.
