[SOLVED] Fixing U1901 Code: Can Network Communication Bus Receive Error

The automobile fault code U1901 indicates a problem with the Stability Control Sensor Cluster in the Anti-Lock Brake System (ABS). This is usually accompanied by the ABS warning light and the engine light turning on.

The cause of this fault code could be a faulty sensor cluster, an open or shorted harness, or a poor electrical connection. It is important to address this issue promptly as it can affect the vehicle’s stability and safety.

The repair process involves visually inspecting the wiring harness and connectors for any damage or corrosion and checking for broken or bent pins.

The repair time for this issue is estimated to be around 1.0 hour.

If you notice the ABS warning light and engine light on, it could be a sign of the U1901 fault code.

  • The automobile fault code U1901 has two main symptoms.
  • The first symptom is the Anti-Lock Brake System (ABS) Warning Light being ON.
  • The second symptom is the Engine Light being ON or the Service Engine Soon Warning Light being ON.
  • It is important to note that these are the only symptoms associated with this particular fault code.

The automobile fault code u1901 can be caused by various issues, including a faulty stability control sensor cluster, open or shorted harness, and poor electrical connection.

  • The automobile fault code U1901 can be caused by a faulty Stability Control Sensor Cluster.
  • It can also be caused by an open or shorted harness of the Stability Control Sensor Cluster.
  • Additionally, a poor electrical connection in the Stability Control Sensor Cluster circuit can also trigger this fault code.

To fix the u1901 automobile fault code, check the possible causes and inspect the related wiring harness, connectors, and components for damage.

  • To fix the automobile fault code u1901, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code U1901 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of diagnosis and fixing the U1901 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.

The U1901 fault code indicates a problem with the CAN Network No. 2 Communication Bus.

This bus is responsible for transmitting signals from the stability control sensor cluster to the ABS module.

The stability control sensor cluster contains the yaw rate sensor, roll rate sensor, lateral accelerometer, and longitudinal accelerometer. If there is an open circuit or a short to power or ground on any of the four circuits, the ABS module will set a DTC. Additionally, if the sensor cluster is not mounted correctly, the ABS module will also set DTCs.

What are the possible causes of the u1901 automobile fault code?

The u1901 fault code in an automobile can be caused by a faulty stability control sensor cluster, an open or shorted harness, or a poor electrical connection in the cluster circuit. This can result in the ABS warning light and engine light turning on. To fix the issue, one should visually inspect the wiring harness and connectors for any damage or corrosion and check for broken or bent pins.

How can the stability control sensor cluster harness be checked for faults?

If the Anti-Lock Brake System (ABS) Warning Light and Engine Light are on, it could be due to a faulty Stability Control Sensor Cluster. To check for faults, inspect the related wiring harness and connectors for any damage or poor electrical connections. Look for broken, bent, pushed out, or corroded connector’s pins. This will help identify if the Stability Control Sensor Cluster harness is open or shorted, and determine the necessary fix.

What steps should be taken to fix the u1901 fault code?

If you’re experiencing an ABS warning light and an engine light on, it could be due to a faulty Stability Control Sensor Cluster or a poor electrical connection. To fix the u1901 fault code, visually inspect the wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector’s pins.
