U0150: Lost Communication With Gateway E

What does U0150 mean?

U0150 is a diagnostic trouble code indicating "Lost Communication With Gateway E". The vehicle's main computer has lost its ability to communicate with a specific module over the data bus. This could be caused by a wiring fault, a blown fuse, or a failed control module.

Symptoms you may notice

• Check engine light (MIL) illuminated on dashboard
• Noticeable change in engine performance
• Unusual sounds or vibrations
• Possible issues with communication bus operation
• Vehicle may enter reduced power mode (limp mode)

Common causes

• Failed control module
• CAN bus wiring fault or short
• Blown fuse to the affected module
• Water intrusion in a connector or module
• Battery voltage too low

What should you do?

This code is a fault on the vehicle data network itself rather than in one named module. Anything on that bus can be affected, safety systems included, and the code alone does not tell you which. Have the network scanned properly rather than assuming it is minor.
