Here are some symptoms to look out for:

  • The fault code U0157 is associated with several symptoms, including the illumination of the engine light or service engine soon warning light.
  • Other symptoms may include issues with the transmission, such as difficulty shifting gears or slipping gears.
  • Additionally, the vehicle may experience problems with acceleration or deceleration, and the engine may stall or hesitate during operation.
  • Finally, the vehicle may experience issues with fuel efficiency, resulting in decreased gas mileage and increased fuel consumption.

The automobile fault code u0157 can be caused by a faulty module or poor electrical connection.

  • The automobile fault code U0157 can be caused by a faulty Information Center Module ‘B’.
  • It can also be caused by an open or shorted Information Center Module ‘B’ harness.
  • Additionally, a poor electrical connection in the Information Center Module ‘B’ circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code u0157, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u0157, 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 U0157 can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of repair is influenced by the repair time, which is commonly charged between $75 and $150 per hour by most auto repair shops.

Therefore, the total cost of diagnosis and fixing the U0157 fault code will depend on the hourly rate charged by the repair shop and the estimated repair time required to fix the issue.

The U0157 fault code is related to a communication issue with the Information Center Module ‘B’. This module is responsible for sending periodic messages to other devices on the Controller Area Network (CAN) bus. The CAN bus is a vehicle bus standard that connects automotive devices without a host computer.

It uses two dedicated wires for communication, CAN high and CAN low. When the CAN bus is in idle mode, both lines carry 2.5V. When data bits are being transmitted, the CAN high line goes to 3.75V, and the CAN low drops to 1.25V, generating a 2.5V differential between the lines.

The CAN bus is not sensitive to inductive spikes, electrical fields, or other noise. The U0157 fault code sets when the Information Center Module ‘B’ fails to send its periodic message on the CAN bus.

This can cause issues with other devices on the bus and may result in poor vehicle performance.

What is the possible cause of the engine light being on when the automobile fault code u0157 is detected?

If the engine light is on and the automobile fault code u0157 is detected, it could be due to a faulty Information Center Module ‘B’, an open or shorted harness, or a poor electrical connection in the circuit. To fix this issue, one should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one fix the issue related to the Information Center Module ‘B’ harness being open or shorted when the fault code u0157 is detected?
