Toyota Code U1002 is a diagnostic trouble code that can affect some models of the Toyota vehicle. This particular code relates to a Lost Communication with Gateway Module (Network Gateway ECU). There are many possible causes for a Toyota Code U1002, such as a faulty movement control bus circuit, 4WD control ECU branch wire or connector, Yaw rate sensor branch wire or connector, Seat belt control ECU branch wire or connector, Clearance warning ECU branch wire or connector, Master cylinder solenoid (skid control ECU) branch wire or connector, Steering angle sensor branch wire or connector, Network gateway ECU main wire or connector, 4WD control ECU, Yaw rate sensor assembly, Seat belt control ECU, Clearance warning ECU assembly, Master cylinder solenoid (skid control ECU), Steering angle sensor, Network gateway ECU, No. 4 junction connector, No. 5 junction connector, No. 6 junction connector, No. 7 junction connector, and No. 1 CAN junction connector. To prevent Toyota Code U1002 from occurring, it is important to be aware of these potential causes and take the necessary steps to mitigate them.
Causes and Solutions for Toyota Code U1002
| Causes | Solutions |
|---|---|
| Faulty movement control bus circuit | Check and repair the circuit as needed. |
| 4WD control ECU branch wire or connector | Inspect the wire and connector, and replace if necessary. |
| Yaw rate sensor branch wire or connector | Examine the wire and connector, and replace if needed. |
| Seat belt control ECU branch wire or connector | Inspect the wire and connector, and replace if required. |
Faulty Movement Control Bus Circuit
The faulty movement control bus circuit is one of the most common causes of Toyota Code U1002. This circuit is responsible for sending signals between the vehicle’s Network Gateway ECU and the 4WD Control ECU. If the circuit is defective, it can lead to the code being triggered. To prevent this from occurring, it is important to inspect the circuit for any problems, and repair it as needed.
4WD Control ECU Branch Wire or Connector
Another common cause of Toyota Code U1002 is a faulty 4WD Control ECU branch wire or connector. This connector is responsible for sending signals between the vehicle’s Network Gateway ECU and the 4WD Control ECU. If the connection is broken, it can lead to the code being triggered. To prevent this from occurring, it is important to inspect the wire and connector, and replace it if necessary.
Yaw Rate Sensor Branch Wire or Connector
The yaw rate sensor branch wire or connector can also cause Toyota Code U1002 to be triggered. This connector is responsible for sending signals between the vehicle’s Network Gateway ECU and the Yaw Rate Sensor. If the connection is broken, it can lead to the code being triggered. To prevent this from occurring, it is important to examine the wire and connector, and replace it if needed.
Seat Belt Control ECU Branch Wire or Connector
The seat belt control ECU branch wire or connector can be another cause of Toyota Code U1002. This connector is responsible for sending signals between the vehicle’s Network Gateway ECU and the Seat Belt Control ECU. If the connection is broken, it can lead to the code being triggered. To prevent this from occurring, it is important to inspect the wire and connector, and replace it if required.
Conclusion
Toyota Code U1002 is a diagnostic trouble code that can affect some models of the Toyota vehicle. The causes for this code can range from a faulty movement control bus circuit to a faulty 4WD control ECU branch wire or connector. It is important to be aware of these potential causes and take the necessary steps to mitigate them in order to prevent Toyota Code U1002 from occurring.
