What is the U0155 fault number? What is the description of the Loss of Communication with IPC (Instrument Panel Control) Module Failure? How do you fix U0155 fault code What are the causes and symptoms of U0155 fault code
What is the U0155 fault code? What does it signify?
Fault code U0155 refers to “Loss Communication with Instrument Panel Control IPC Module” . This code is activated when communication between powertrain control module (PCM), and instrument cluster control (IPC), module is lost.
Modern vehicles are equipped with more than 20 microcontrollers and control modules. All control modules and systems communicate via the Controller Area Network (CAN) bus. The instrument panel transmits information to the driver about the operation and general status of the modules. Warning lamps are one example of this. They show information about the safety system status, such as vehicle speed, engine temperature, coolant, and other important information.
Your vehicle can be affected if the communication link between IPC and PCM fails. The PCM will be unable to communicate with other control modules if the data transfer bridge fails. This means that the PCM can’t monitor the operation and efficiency of critical control modules. The check engine light will activate if there is a disconnect between the PCM and IPC.
Your vehicle’s instrument cluster houses the IPC module. Although it is possible to repair it if necessary, it must be reprogrammed in accordance with the factory-installed antitheft protocols. If the engine is not starting, it must be reprogrammed.
The U0155 fault code can affect vehicles of all makes and models, including but not limited to Mercedes, Honda, Mazda (Jaguar), Jeep, Volkswagen, Chevrolet Hyundai, Toyota, Dodge Acura, Chrysler, Subaru, Subaru, and Toyota.
What is the U0155 Fault Code
The following are the most frequent causes of the U0155 fault code:
- – Dead battery or weak battery
- – Panel damaged by an instrument
- – Defective IPC module
- – Connectors that are loose or damaged to the IPC Module
- – Open or short circuit problems on the CAN bus
- – One or more defective control modules
What are the symptoms for the U0155 Fault code?
These symptoms may be present in vehicles with U0155 codes.
- – Illumination for the check engine light
- – The instrument panel does not work properly
- – All lights on instrument panel are on
- – There are no lights on the instrument panel
How to Fix the U0155 Fault Code
These codes should be addressed before any other codes are added to the U0155 fault code.
The following repairs can help resolve the U0155 fault code
- – Checking the voltage and replacing the battery, if needed
- – Testing the fuses in the IPC module
- – Repair of damaged cables or connectors to IPC module
- – Fixing connection problems between modules
- – Resolving connection issues between IPC and PCM
- CAN bus cables: Repairing short or open circuits, checking them
- – Replacing IPC Module
How serious is the U0155 Fault code?
Fault code U0155 could cause communication interruptions between the PCM, other control modules, and make your vehicle difficult or impossible to start. It can also cause safety problems during driving. If the PCM is unable or unwilling to communicate with the TCM (transmission control module) or control throttle, the PCM could enter fail-safe mode. When this code has been set, you should not use the tool. This code should not be ignored and should be fixed as soon as possible.
