Detroit DD13 EPA07 (2007-09) Fault Code: SPN 168 FMI 14 (MCM, CPC) ECU Power Down Not Completed (Main Battery Terminal Possibly Floating)
Posted by PerDiezel Solutions on
NOTE: For EPA 10 vehicles, this code has been turned off with common powertrain controller (CPC) software level v21.00 or higher. If found active, update device software. NOTE: If vehicle is equipped with a battery disconnect switch, it must also be inspected for proper connections. NOTE: This fault indicates the loss of battery voltage to pin 1 of the common powertrain controller (CPC) #2 connector. NOTE: Code indicates a loss of battery voltage to pin 1 of the Common Powertrain Controller #2 connector. If the vehicle is equipped with a battery disconnect switch it may also be the cause.
