What is the U0104 Fault code? What does it mean
The automotive industry’s most common circuit for control modules and other electronic parts to communicate is the. “Controller Area Network (CAN)” bus. The manufacturer has preprogrammed the modules with the required data. Operator information and commands are also exchanged over the CAN bus.
Two special copper wires called “CAN High” (High) “CAN Low” These cables are used to communicate (lower). They come in different colors. The wires are arranged in different colors. When data transmission is not happening, both wires are rated at 2.5V. Data transmission causes the high priority wire to rise to 3.75V while the low priority line drops down to 1.25V. This creates a 2.5V voltage difference between the lines. The voltage difference between bus lines determines communication.
The vehicle’s speed can be controlled by both the powertrain control and cruise module. If the PCM detects an issue with the cruise controller system, it will test the entire system to identify the source. The U0104 malfunction codes are set if other control modules or the PCM cannot receive any signal from cruise control control module.
The U0104 fault code can affect vehicles of all makes and models, including but not limited to Ford, Honda, Dodge, Jeep, Dodge, Volkswagen and Jaguar.
What causes the U0104 Fault code?
Here are some reasons to assign U0104 as a fault code:
- – The wires are damaged, melted, broken, or corroded, which can cause an open or brief circuit in the CAN bus
- – Poor electricity due to open or short circuit problems in wiring or loose connections.
- – Broken or bent pins on DSCC Module Sockets
- – Blown fuse
- – Defective DSCC module (rarely)
What are the symptoms for the U0104 fault code?
These symptoms may be present in vehicles with U0104 codes.
- – Illumination for check engine light
- – Cruise control not working
- – ABS/TRAC/ESC warning lamps might be activated in certain applications.
- – Setting related fault codes
How to Fix the U0104 Fault Code
There are several repairs that can resolve the U0104 fault code:
- – Repair or replacement for damaged, melted and corroded wires that are causing an open or brief circuit on the CAN bus
- – Repair of or replacement of damaged or melted, corroded or broken wires to DSCC modules causing an opening or short circuit
- – Replacing blown fuse
- – Clean the corroded DSCC Module Connection Sockets
- Repair bent or broken pins
- – Replacing the faulty DSCC modules
How Serious Is the U0104 Fault Code
Control module failures should be treated seriously. Your cruise control system won’t work if this code has been set. Although this is not a danger, it can cause problems with your cruise control system. In some cases the cruise control module may be integrated with the steering column control module to activate the ABS/ESC/TRAC warning lamps. This could lead to problems with security systems. This situation should be rectified immediately.
