The instrument panel not receiving the EECU message indicates that the Vehicle Control Unit (VECU) cannot receive signals from the Engine Control Unit (EECU). This situation is usually caused by loose connectors and should be addressed by a professional technician as soon as possible. Fault line detection for the instrument panel not receiving the EECU message: 1. Disconnect the boost pressure temperature sensor and turn the ignition to the ON position. 2. Measure the resistance between pin 11 (CAN-H) and pin 12 (CAN-L) of the communication diagnostic interface in the cabin as 69 ohms, then turn the ignition to the ON position. 3. Disconnect the VECUSL3 plug and measure the termination resistance between pin 6 and pin 7 as 130 ohms, and between pin 3 and pin 4 as 133 ohms, with no obvious issues found. 4. Disconnect the VECUSL3 plug and turn the ignition to the ON position. Measure the voltage to ground for pin 6 as 1.9V, pin 7 as 3V, pin 3 as 2.4V, and pin 4 as 2.4V. It is determined that the communication voltage from the EECU to the VECU is abnormal. 5. Disconnect the main power supply.
