DEF Error Codes
Hope this saves someone some pain and money... Had the following error codes from my ScanGauge D...
ID: 1569 - Engine Protection Torque Derate
FM: 15 - Data Valid but above normal operating range (least severe level)
ID: 5246 - Aftertreatment SCR Operator Inducement Severity
FM: 0 - Data valid but above normal operational range
ID: 5746 - Aftertreatment 1 Diesel Exhaust Fluid Dosing Unit Heater Relay
FM: 4 - Voltage below normal or shorted low
ID: 5491 - Aftertreatment 1 Diesel Exhaust Fluid Line Heater Relay
FM: 4 - Voltage below normal or shorted low
Had RED Check engine light so didn't want to move rig (2015 Dynamax Force)... Checked fuses, Wiring, called ScanGauge to get definition of codes and did allot of research. After long discussion with Freightliner.... Had them dispatch mobile service... $732 later for an $8 Resister. Not covered by warranty... Tech replaced the resister in the photo and the error codes cleared.
I have found some great info in this forum, I hope my experience save someone some pain and aggravation.
