RAM Code U113E

Ram Code U113E is a diagnostic code indicating lost communication with an Intelligent Battery Sensor. This code is often seen in RAM vehicles, which may show a short or open circuit in the positive battery cable, an open ground circuit, a LIN bus circuit open, or an issue with the Intelligent Battery Sensor. The IBS is an electrical shunt with a microprocessor mounted in line with the negative battery cable. It monitors current flow, voltage, and temperature to calculate the battery’s state of charge, resistance, charge delivered, and more. When this code is triggered, it is important to address the underlying cause to ensure the battery is functioning properly.

Causes and Solutions of RAM Code U113E

Cause Solution
Open or Shorted to Ground Fused B(+) Circuit Check and replace any open or shorted fuses in the vehicle.
Open Ground Circuit Check the ground circuit for continuity and replace any broken connections.
LIN Bus Circuit Open Check the LIN bus circuit for continuity and replace any broken wires.
Intelligent Battery Sensor Replace the Intelligent Battery Sensor to restore functionality.

Open or Shorted to Ground Fused B(+) Circuit

The RAM Code U113E is commonly triggered by an open or shorted-to-ground fused B(+) circuit. This could be caused by a faulty fuse, which can be determined by using a multimeter to check the continuity of the circuit. If the fuse is found to be inaccurate, then it should be replaced.

Open Ground Circuit

Another possible cause of RAM Code U113E is an open ground circuit. This can be caused by broken connections or wiring, which can be located and replaced. Checking the circuit’s continuity can help identify any open connections, and then the connections can be replaced.

LIN Bus Circuit Open

The LIN bus circuit can also be the cause of RAM Code U113E. This is a communication network that is responsible for sending data between various components of the vehicle. A broken or open connection can cause the code to be triggered, so the circuit should be checked for continuity, and any fractured wires should be replaced.

Intelligent Battery Sensor

The Intelligent Battery Sensor (IBS) is an electrical shunt with a microprocessor that monitors the battery’s current, voltage, and temperature. If the IBS is malfunctioning, then RAM Code U113E will be triggered. In this case, the IBS should be replaced to restore functionality and prevent the code from being started.

Conclusion

RAM Code U113E is a diagnostic code often seen in RAM vehicles and indicates a lost communication with an Intelligent Battery Sensor (IBS). This can be caused by various issues, such as an open or shorted-to-ground fused B(+) circuit, an open ground circuit, a LIN bus circuit open, or a problem with the Intelligent Battery Sensor. To ensure the battery is functioning properly, it is important to diagnose and address the underlying cause of the code. If the RAM Code U113E is triggered, the Intelligent Battery Sensor should be checked and replaced.
