U0162 code meaning
Lost Communication With Navigation Display Module
What U0162 means
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.

Common causes of U0162
- Most likelySupply interrupted, e.g. loose terminal at the fuse box (Subaru TechTIPS)

Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0162 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 62 | The exact fault in that area. |
What to do next
- Note U0162 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.
