Challenger Posted January 29, 2016 Share Posted January 29, 2016 Probably should take it to a dealer. Maybe a software program problem or a bad cluster. Clusters are modules, just like the EECU. You could check the connector on the back of the cluster, but I would take it to the dealer. Quote Link to comment Share on other sites More sharing options...
Keffer inc Posted January 30, 2016 Share Posted January 30, 2016 2015? Is it under warranty? The truck is rather new for my knowledge... Quote Link to comment Share on other sites More sharing options...
claude m Posted January 30, 2016 Author Share Posted January 30, 2016 46000 km, out of warranty, since September ,dealer has not seen problem like this for this new of a truck. unplugging of dash connectors seem to reset dash but not guard dog. truck is a 6x6 plough/salt truck with bosch rextrof controller, speed signal from dash is needed to control salt application. when dash dies signal is lost.
