What is the reason for the sudden appearance of five warning lights in the Roewe RX5?
2 Answers
Here are the reasons for the sudden appearance of five warning lights in the Roewe RX5: 1. ECU CAN bus failure: Poor contact in the ECU CAN interface. 2. Excessive dirt and carbon deposits, abnormal air flow: Unable to accurately control the normal air intake, resulting in unstable gas content and poor engine performance. 3. Low fuel pressure: Combined with poor constant pressure performance, leading to low system atomization level, making the car difficult to start. Below are the types of dashboard indicator lights: 1. First category: Daily indicator lights, such as turn signal lights, light indicator lights, seat belt indicator lights, cruise control indicator lights, parking indicator lights, etc. These only serve to indicate the working status of various vehicle functions. 2. Second category: Warning indicator lights, such as fuel level indicator lights, windshield washer fluid level indicator lights. 3. Third category: Fault indicator lights, including engine (exhaust system) fault lights, oil system fault lights, battery and power generation system fault lights, etc. These fault indicator lights rarely light up under normal circumstances.
It was quite alarming when five warning lights suddenly lit up on the dashboard while driving. This is a common occurrence with the Roewe RX5 as a smart SUV. The primary cause could be a system alert due to a low battery charge, where lights for ABS, ESP, engine faults, etc., often trigger a chain reaction. Alternatively, it might be a false sensor reading, such as a faulty wheel speed sensor sending incorrect signals that set off multiple warnings. Another possibility is a blown fuse or poor wiring contact, especially during humid weather when wires are prone to aging. I recommend pulling over immediately, turning on the hazard lights, and not continuing to drive—safety first. Connect an OBD scanner to read the fault codes for an accurate diagnosis. Regular maintenance checks on battery life and electrical connections can prevent many such surprises. Electronic components can be unpredictable; sometimes a software update fixes the issue, but for more serious problems, a visit to a professional repair shop is necessary.
