U0155 Dodge Code - Lost Communication With Instrument Panel Cluster Control Module
Quick Answer
The U0155 diagnostic trouble code (DTC) for Dodge vehicles indicates that there is a communication problem between the Engine Control Module (ECM) and the Instrument Panel Cluster Control Module (IPCCM). Common causes include Faulty wiring or connectors between the ECM and IPCCM, Defective ECM or IPCCM, Corrosion or damage to the communication bus lines. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U0155 Dodge Description
The U0155 diagnostic trouble code (DTC) for Dodge vehicles indicates that there is a communication problem between the Engine Control Module (ECM) and the Instrument Panel Cluster Control Module (IPCCM). This means that the ECM is unable to receive data from the IPCCM, which can lead to various issues with the vehicle's performance and functionality.
Common Causes of U0155 Dodge
- Faulty wiring or connectors between the ECM and IPCCM
- Defective ECM or IPCCM
- Corrosion or damage to the communication bus lines
- Software issues or programming errors
- Electrical interference from aftermarket accessories
Symptoms of U0155 Dodge
- Inaccurate or erratic readings on the instrument cluster gauges
- Dashboard warning lights flashing or staying illuminated
- Loss of functionality in the vehicle's electronic systems
- Transmission shifting problems
- Engine stalling or misfiring
How to Fix U0155 Dodge
- Begin by conducting a visual inspection of the wiring and connectors between the ECM and IPCCM to check for any signs of damage or corrosion.
- Use a diagnostic scan tool to retrieve the trouble codes and data from the ECM and IPCCM to pinpoint the exact cause of the communication failure.
- Test the communication bus lines for continuity and proper voltage levels.
- If necessary, replace any faulty wiring, connectors, or modules that are causing the communication issue.
- Clear the DTCs from the ECM and IPCCM and perform a test drive to ensure that the communication has been restored and the symptoms have been resolved.
Cost to Fix U0155 Dodge
The typical repair costs for addressing a U0155 code on a Dodge vehicle can range from $200 to $500, depending on the specific cause of the communication failure and the cost of parts and labor. It's important to note that the diagnosis time and labor rates at auto repair shops can vary, so it's recommended to obtain quotes from multiple sources to ensure a competitive price. Keep in mind that rates may be higher at dealerships or in metropolitan areas, while independent shops may offer more affordable options.

2. What are the common symptoms of the U0155 code on a Dodge?
Common symptoms include a non-functional instrument cluster, no speedometer or tachometer readings, warning lights staying on, or erratic gauge behavior.
3. What causes the U0155 code to appear on a Dodge?
Possible causes include a faulty instrument cluster, damaged communication wiring or connectors, a malfunctioning CAN bus network, or a failed control module.
4. Can a dead battery cause the U0155 code on a Dodge?
Yes, a dead or weak battery can disrupt communication between modules and potentially trigger the U0155 code.
5. How do I diagnose the U0155 code on a Dodge?
Start by checking the battery voltage, inspecting wiring and connectors for damage, and using a scan tool to verify communication with the IPC control module.
6. Is the U0155 code on a Dodge serious?
While it may not directly affect drivability, it can lead to inaccurate instrument readings or loss of important warning indicators, which could increase safety risks.
7. How do I fix the U0155 code on a Dodge?
Repair solutions may include reconnecting or replacing damaged wiring, cleaning corroded connectors, updating module software, or replacing a faulty instrument cluster.
8. Can I drive my Dodge with the U0155 code?
While the vehicle may still be drivable, it’s not recommended due to potential safety concerns from inoperative gauges or warning lights.
9. How much does it cost to fix the U0155 code on a Dodge?
Costs can vary widely based on the issue, ranging from $50 for minor wiring repairs to $800 or more if the instrument cluster needs replacement.
10. Do I need a professional mechanic to fix the U0155 code on a Dodge?
If basic checks like inspecting wiring and battery voltage don’t resolve the issue, professional diagnosis and repair are recommended due to the complexity of the CAN bus network.
