U0522Invalid Data Received From Door Switch G
- Generic OBD-II code · Network
- How the car detects it
- J2012 provides seven door switch units, and G is the last of them. Few vehicles need that many networked switch packs, and no manufacturer publishes what G stands for or documents U0522. Where such a unit exists it works like its siblings: it supplies its button states when asked, and the receiver ignores them once a frame is malformed, out of range or carries an invalid counter. After a switch pack has been replaced or the body controller reconfigured, a variant or software level that does not suit the vehicle can produce exactly this pattern; FCA's Cherokee bulletin 08-013-15 shows door-switch codes being cleared by BCM software and a restored configuration. All other doors and switches carry on working. U0221 is the partner for complete silence.
