What is the reason for the central control malfunction after replacing the new battery?
1 Answers
After replacing the battery, the central control may malfunction due to disconnected wiring. Here are the specific details: 1. Cause of malfunction: When replacing the battery, to avoid short-circuiting the positive and negative terminals, the battery wiring may be bent and separated as much as possible. This can sometimes lead to disconnection, especially if an additional anti-theft alarm was installed after purchasing the car, which requires cutting the original power supply wiring for connection, compromising the wiring's sealing. Over time, exposure to air can cause oxidation. 2. Solution: Check if the wiring is properly connected and if there are any breaks, particularly in manually connected areas.
