Saturn U1301 Code is an internal diagnostic trouble code (DTC) which is triggered when the powertrain control module (PCM) detects a voltage condition on the class 2 data circuit which is in the normal operating voltage range. This code is set when the PCM does not detect any valid messages on the Class 2 circuit or when the voltage condition detected on the Class 2 circuit is low for three seconds. This code is set by loss of communication and can cause a variety of issues if not diagnosed and repaired properly. To solve the code, it is important to understand the main causes and solutions as it relates to Saturn U1301 Code.
Causes and Solutions of Saturn U1301 Code
Cause | Solution |
---|---|
Class 2 serial data line was in a high state for 3 seconds due to a short to VREF or system power | Check the voltage on the Class 2 serial data line and repair any shorts to VREF or system power. |
One or more modules on Class 2 line has an short to power | Check for shorted modules on the Class 2 line and repair any shorts to power. |
Loss of communication | Diagnose and repair the shorted Class 2 serial data line. |
Failed module | Replace any failed modules on the Class 2 line. |
Saturn U1301 Code is a trouble code that is triggered when a voltage condition is detected on the class 2 data circuit which is in the normal operating voltage range. This code is set by loss of communication and can cause a variety of issues if not diagnosed and repaired properly. It is important to understand the causes and solutions of Saturn U1301 Code in order to properly diagnose and repair the code. This article provides a table of the common causes and solutions associated with Saturn U1301 Code.
Class 2 Serial Data Line Voltage
The most common cause of Saturn U1301 Code is a voltage condition on the class 2 serial data line. This can be caused by a short to VREF or system power. In order to repair this issue, it is important to check the voltage on the class 2 serial data line and repair any shorts to VREF or system power.
Shorted Modules on the Class 2 Line
Another common cause of Saturn U1301 Code is one or more modules on the Class 2 line that have a short to power. This can cause the voltage to drop and cause the code to be set. It is important to check for shorted modules on the Class 2 line and repair any shorts to power.
Loss of Communication
The code is also set when the PCM does not detect any valid messages on the Class 2 circuit or when the voltage condition detected on the Class 2 circuit is low for three seconds. This is caused by loss of communication, and it is important to diagnose and repair the shorted Class 2 serial data line in order to solve the code.
Failed Modules
Finally, Saturn U1301 Code can be caused by failed modules on the Class 2 line. It is important to replace any failed modules on the Class 2 line in order to solve the code.
Conclusion
Saturn U1301 Code is an internal diagnostic trouble code which can cause a variety of issues if not diagnosed and repaired properly. It is important to understand the common causes and solutions of Saturn U1301 Code in order to properly diagnose and repair the code. By understanding the causes and solutions associated with Saturn U1301 Code, you can ensure that the code is properly diagnosed and repaired.
