OBD2 Code: U0155

Description: Lost communication with instrument panel cluster control module.

Definition: This code indicates that the vehicle’s onboard computer has lost communication with the instrument panel cluster (IPC) control module. The IPC is responsible for displaying important information such as speed, fuel level, and warning indicators to the driver. A loss of communication can result in incorrect or missing data being displayed on the dashboard.

Typical Severity: Moderate

Common Causes

• Loose or corroded wiring connections
• Interference from other electronic devices
• Software issues in the control module
• Vehicle battery voltage too low or too high

 

Common Misdiagnosis

Common Diagnostic Steps:

• Check for any other communication-related codes that may indicate a network issue.
• Inspect the IPC wiring harness and connectors for damage, corrosion, or loose connections.
• Verify the power and ground circuits to the IPC are functioning correctly.
• Use a scan tool to check if the IPC is receiving data from other modules on the network.
• If possible, perform a module reset or reprogramming of the IPC.
• Test for continuity in the CAN bus lines between the IPC and other control modules.
• If all else fails, consider replacing the instrument panel cluster control module.
