What to do if the instrument panel does not receive EECU messages?
1 Answers
The solution when the instrument panel does not receive EECU messages is: simply reconnect the connectors. If the instrument panel does not receive EECU messages, it means the Vehicle Control Unit (VCU) cannot receive signals sent by the Engine Control Unit (EECU). This situation indicates an open circuit between the Engine Control Unit and VCU. Similar faults, such as message timeouts, also belong to open circuit issues. The Engine Control Unit is the computer board, also known as the ECU, installed on the engine block. It serves as the engine's central control system, equivalent to the human brain. The main computer boards (also called control units) in a vehicle include the engine computer, automatic transmission computer, body control system computer, and comfort system computer.
