U0162Lost Communication With Navigation Display Module
- Generic OBD-II code · Network
- How the car detects it
- U0162 indicates that the navigation display, typically the screen unit of the head unit, no longer answers. Subaru documents it in two settings. TechTIPS 10/2015 describes a 2015 Legacy/Outback with Fujitsu Ten navigation that stored U0162 together with U0100, U0101 and U0122; the real cause was a wire not locked into the under-hood fuse box, which unseated the 30 A fuse feeding the IG2 relay. Bulletin 07-205-22 (2021 Crosstrek, 2020-22 Forester) has the rear vehicle detection module store U0162 and light the SRVD warning; new SRVD software improves CAN traffic with the head unit. U0163 is the navigation control unit, U0463 implausible display data. Map and screen may fail; no MIL.
