Range, A and B odometer readings?????
Hey Guys. My 2012 Switchback all of a sudden started giving wrong readings on the Range, A and B odometers. The Range states something like 939 miles and A and B are 434 miles. These readings do not stay the same either, they vary and A and B can be reset to 0 by disconnecting the battery for a bit, but not Range. Only to have them go back to incorrect readings within a minute or so. Everything else on the bike seems to work fine and the bike runs and cranks fine. The DTC codes are "P1632, odometer learned up" , PN34271-12A and PN67096-12 .I can clear all of them out. Any ideas out there? Thanks

DESCRIPTION AND OPERATION
If the speedometer mileage is higher than the mileage in the
ECM, the ECM will set a DTC P1632 and increase its mileage
to match the speedometer. This will normally occur when the
ECM is replaced or if continuous battery is not present on [78-
2] terminal 18 of the ECM. If this code is set, verify the
speedometer or ECM have not been replaced with a used part
from another vehicle. Clear the DTC. See 2.1 INITIAL DIAGNOSTICS,
Odometer Self-Diagnostics. If the code returns,
the ECM may not be powering down properly. Verify that 12V
is continually present on [78-2] terminal 18.

Hey bustert, thanks for the reply. The ecm,, bcm or the speedometer have not been replaced. Have had the bike about 4 years now and this just started last month. Do you know what the pin-out is on the ecm and bcm plugs? ie, how do i count the pins? I can clear all DTC codes and reset and disconnect the battery with no better results.
