- Speedometer or instrument cluster needles bouncing or freezing
- Transmission may shift harshly or default to safe limp gear
How much does it cost to fix?
Repair costs for code U0155 depend on the specific underlying root cause, ranging from simple DIY checks to component replacement. The table below lists the most common causes and rough price ranges in USD:
- Cracked solder joints on instrument cluster circuit board
- Loose electrical plug behind the instrument cluster
- Blown cluster gauge fuse

About this code
Code U0155 occurs when other computers cannot communicate with the dashboard instrument cluster. Common on GM and Ford vehicles, cracked solder pins on the cluster connector cause gauges to cut in and out intermittently. Drive safely and monitor speed via GPS until fixed.
