Causes Of U1504 In Jeep Cherokee

The U1504 code in a Jeep Cherokee refers to an implausible message length received from the steering angle sensor (SAS), indicating a potential loss of communication.

This can be caused by various factors and requires diagnostic testing and repair to fix.

The U1504 code in a Jeep Cherokee indicates a problem with the steering angle sensor (SAS) or the communication between the SAS and other modules in the vehicle.

Here are the common causes of U1504:

• Faulty steering angle sensor (SAS): The SAS is responsible for measuring the position of the steering wheel and transmitting that information to other modules in the vehicle. If the SAS is faulty or malfunctions, it can trigger the U1504 code.
• Loss of communication between SAS and other modules: The steering angle sensor needs to communicate with other modules, such as the engine control module (ECM) or the anti-lock brake system (ABS) module. If there is a loss of communication between the SAS and these modules, it can trigger the U1504 code.
• Data mismatch or error in sensor readings: The U1504 code can also be caused by a data mismatch or error in the sensor readings. This can occur when there is a discrepancy between the actual steering angle and the angle that the sensor is detecting.
• Low battery voltage: Although not as common, low battery voltage can also trigger the U1504 code. Low voltage can cause a data mismatch or interruption in communication between the SAS and other modules.
• Wiring or connection issues: Faulty wiring or loose connections can also lead to the U1504 code. If there is a break in the wiring or a loose connection between the SAS and other modules, it can disrupt the communication and trigger the code.

It is important to have the U1504 code diagnosed and repaired as soon as possible to ensure the proper functioning of the steering system in your Jeep Cherokee.

If you are experiencing any symptoms related to this code, such as unusual steering behavior or warning lights on the dashboard, it is recommended to seek the assistance of a qualified mechanic.

They will be able to accurately diagnose the cause of the code and perform the necessary repairs to resolve the issue.
