U0151: Lost Communication With Restraints Control Module
A generic network and communication trouble code, same meaning on every brand.
Yes - engine and brakes are unaffected. But the airbag computer is off the network, and the safe assumption is no airbags or pretensioners until it is back. Prompt repair.
Symptoms
- Airbag warning light
- Other modules logging communication codes
- Sometimes appears after audio or alarm installations
- No mechanical symptoms
Likely causes, most common first
- Airbag module lost power or ground
- CAN wiring to the module damaged
- Water intrusion under seat or console where the module lives
- Failed airbag module
Read U0151 yourself before paying for diagnosis
A basic Bluetooth OBD-II scanner ($20-40) plugs into the port under the dashboard and shows this code with live sensor data on your phone - useful both for confirming the fix and for talking to a shop from an informed position.
What is going on and how it gets diagnosed
U0151 means the rest of the car stopped hearing from the restraints control module - the airbag computer went silent on the network. Whatever the cause, the practical consequence is the same as any airbag fault: the system cannot be trusted until communication returns.
The module typically lives under the center console or a front seat, bolted to the floor - prime territory for spilled drinks, wet carpet from a leaking windshield, and stray screws from aftermarket installs. A dead module often turns out to be a drowned module, and the carpet under it tells the story. The other classic is an install gone wrong: audio systems and remote starters spliced near the console can nick the module's power feed. Check history and simple supplies before pricing a new module, because modules also need coding to the car once replaced.
Repair options and cost
Typical US independent-shop ranges, parts and labor. Dealers run higher; regional labor rates vary.

“I have read several things about EBCM and the control power circuit being above threshold and wondering if this is a recall for this model? I am getting 3 error codes C0800, B1325, & U0151 for this vehicle. (General Motors is recalling over 449,000 SUVs and pickups (2023–2024 Cadillac Escalade, Chevy Suburban/Tahoe, GMC Yukon, and select Silverado/Sierra 1500) due to a software fault in the Electronic Brake Control Module (EBCM) . This issue prevents the brake warning light from illuminating if brake fluid drops, increasing crash risk.) It's showing the same issues as above.”2023 Chevrolet Traverse · Dec 2025
