B2204-00 means the restraint control module is configured for a different build than the truck it is installed in. The module expects a set of restraint components, finds a different set, and refuses to arm anything.
Every Occupant Restraint Controller carries a configuration that describes the truck it belongs to: which airbags are present, which sensors report in, which seat and cab options the restraint system covers. The module compares that configuration against what it actually sees on its circuits. A mismatch between the two is what sets B2204-00.
This code shows up most often after a module swap. A controller pulled from a truck with different equipment, a different cab, or different seats will not match, even when the part number looks close. The module is not broken in the usual sense, it is set up for a vehicle that is not this one.
Nothing about B2204-00 is a crash record. It is a present tense hardware and setup fault the module reports because its stored configuration does not agree with the vehicle. Crash data sits in a different place: it is written only when airbags deploy, locks itself in, and is exactly what the mail-in reset service is built to clear.
Reset and configuration are two different operations. Our mail-in service clears stored crash data from the module, and that is worth doing when the module came out of a deployed vehicle. Matching the configuration to your truck is a separate step that takes factory level programming. Call 501-988-0611 before you install a swapped module and we will walk you through which part you actually need.
Our lookup shows only Ram for B2204-00. It is a common finding on trucks where someone tried to solve an airbag light by fitting a module from the salvage yard without checking how closely the donor matched.
Compare the module you have against the one the truck was built with before anything else, since a configuration mismatch is almost always a parts problem rather than a repair problem. Check cab style, seat equipment, and side airbag content on both. If the installed controller came from a different build, source a module that matches your truck.
