U0216Lost Communication With Door Switch B
- Generic OBD-II code · Network
- How the car detects it
- U0216 reports that door switch unit B has dropped off the network. FCA uses the code on the 2014 Jeep Cherokee (KL) and its text names the driver door switch as the missing partner, so B is the driver's panel there. Bulletin 08-013-15, which replaced 08-111-14 and was also issued as rapid response transmittal 15-021, covers vehicles built up to 11 July 2014: after the battery had been disconnected, the cluster could show Start/Stop Not Available and the BCM held U0216. The cure was new BCM software, followed by restoring and aligning the Proxi configuration whenever the start/stop message had appeared. On other vehicles a wiring fault in the driver door remains the usual suspect. No MIL.
