U0517 code meaning
Invalid Data Received From Door Switch B
What U0517 means
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.

What each part of U0517 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 17 | The exact fault in that area. |
What to do next
- Note U0517 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
