The Detroit HRW wheel speed troubleshooting sheet documents Detroit fault code SPN 1592 FMI 19, which sets when the high resolution wheel speed (HRW) signal is erroneous. This 2-page PDF belongs to the Detroit DD Series (EPA 2007-Current) DTC library and guides a technician through the confirmation and repair sequence for the code. It is drawn from Detroit Power Service Literature and republished by TruckFaultCodes.com (2017).
After connecting the diesel diagnostic tool, the procedure checks for CPC4 battery-voltage faults (SPN 168) and Controller Area Network line faults (SPN 625), confirms the parameter configuration if the CPC4 was reprogrammed, then powers the modules down for five minutes and retests to see whether the code remains active.
