U0517Invalid Data Received From Door Switch B
- Generic OBD-II code · Network
- How the car detects it
- Door switch B is the only letter of this series with a published manufacturer assignment. FCA bulletin 08-013-15 for the 2014 Jeep Cherokee (KL) gives the partner code U0216 as lost communication with the driver door switch; it showed up after the battery had been disconnected, together with a Start/Stop Not Available message, and was cured with new BCM software and a restored proxi configuration. U0517 itself is not documented by any manufacturer: here the driver's switch pack keeps sending, but the content is rejected. Since this pack usually holds the master buttons for every window, the rear window lockout and often lock and mirror controls, corrupt data can disable several functions at once. Battery voltage, BCM software and the driver door harness are the first checks.
