However, even the most reliable machines suffer from wear and tear, particularly as they age. For Pajero owners—especially those driving models produced between 2006 and the present (Generation 4)—few dashboard warnings cause as much confusion and frustration as the diagnostic trouble code .

The C1456 code is officially defined as an detected all the time. The Pajero’s Super Select 4WD system relies on a set of five small switches (sensors) mounted on the top of the transfer case to report the mechanical position of the shift forks to the ECU.
