1 vehicles · 1 makes
Most Reported On
B2204 is an OBD-II diagnostic trouble code meaning “ECU Configuration Mismatch (Chrysler/Dodge/Jeep/RAM).” A manufacturer-specific body code. On Stellantis/FCA vehicles (Chrysler, Dodge, Jeep, RAM) factory service information defines B2204 as ECU Configuration Mismatch: a module — typically the Wireless Ignition Node (WIN) or RF Hub — finds that its stored configuration for model year, vehicle line, body style, or market country does not match the vehicle configuration broadcast on the CAN bus. It is a programming/configuration fault, not a wiring failure, and is usually seen after a module is replaced or swapped from another vehicle; it can cause immobilizer or no-start behavior. Other makes assign B2204 differently (Acura: B-CAN communication line error; Mazda: GPS antenna circuit open/short; Mitsubishi: coding data mismatch), so confirm the definition for your make. This code is most commonly reported on 2018-2024 Jeep Wrangler (Sport, Sahara, Rubicon, 4xe).
