Detroit DD13 EPA10 (2010-13) Fault Code: SPN 84 FMI 13 (MCM) J1939 Wheel-Based Vehicle Speed Sensor Signal from Source #1, #2, or #3 is Missing
Posted by PerDiezel Solutions on
DESCRIPTION:J1939 vehicle speed sensor signal missing. MONITORED PARAMETER:Vehicle Speed Sensor (VSS). TYPICAL ENABLING CONDITIONS:1. Rpm greater than 1500.2. Torque demand on. MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:10 seconds DASH LAMPS:MIL VERIFICATION:1. Rpm greater than 1500.2. Torque demand on. NOTE: If codes for other modules are present, fix those first. PROBABLE CAUSES:1. Improper programming of the CPC (Common Powertrain Controller).2. Other failed modules on the truck (Transmission, ABS, Cab controller, etc…).3. Battery/battery cable issues, or electrical issue on truck.
