What should I do if the instrument fails to receive the eecu message?

The on-board instrument did not receive the eecu message, indicating that the vehicle control module did not receive the signal from the engine control module, which was usually caused by the loose connector. Reconnect the connector and replace the vehicle control module or engine control module if necessary.

There are many modules on the vehicle, which communicate and exchange information with each other through the communication line Can. Instrument and engine computer are both modules, and there is no signal indicating that there is something wrong with the communication line between them, so it is necessary to check the communication line emphatically.

If the instrument panel displays a fault code, only the instrument has not received the EECU can message. When the key opens the starting gear, the starter will idle and the engine will not catch fire. However, when replacing the starter, the starter will catch fire instantly. When this kind of fault occurs, the engine can't be started due to the fault of the EECU power supply circuit of the electronic control engine.

Turn the key to the ON position, and the instrument will display the fault code. The instrument did not receive EEC information, and the vehicle started. The starter turned the engine, but there was no sign of landing. When trying to connect the diagnostic instrument, the vehicle control module fault diagnosis system can enter, but the engine control module fault diagnosis system cannot enter, indicating that the communication is not connected.
