Estimados, en otro foro indicaron que el tema de Cod 173 se debe a una falla del software de traccion y que se soluciona con una actualizacion del software , este es el texto en ingles.
Rear Differential Control Module Reprogramming
February 20, 2014
The All-Wheel-Drive (AWD) indicator may be illuminated or an AWD Disabled message may be displayed in the Driver Information Center (DIC) on some 2013-2014 Encore and Trax (Canada only) models equipped with AWD.
Code 173 may be set. Code 173 is not a DTC, but an action taken by the Rear Differential Control Module. If any DTCs are set, follow the diagnostics in the appropriate Service Information.
This condition may be caused by the software in the Rear Differential Control Module (RDCM). Updated Rear Differential Control Module software is being developed to address this condition. If Code 173 is observed, It’s necessary to reprogram the Rear Differential Control Module. The updated calibration will be available in TIS2Web soon.
