I recently picked up a used 2008 Renegade 800, and have been recently experiencing issues with the speedo. The unit was displaying the mileage and vehicle speed until last week when everything quit working.

I still had the tach function and hour meter working properly but not speedometer or odometer function.

Took it into the dealer to have the ECM unit updated and a maintenance code cleared along with a spare key programmed.

I bought a new speed sensor and trouble shot all electronics including the diodes and all was operating as per OEM specification.

I installed a new speed sensor yesterday and the speedometer function has returned, but the unit will not recall the odometer reading.

Before this all happened the reading was 2112 kms and now it reads "0". Am I missing something here?
