Normal Operation and Fault Conditions

WARNING: This page is about a different car, the 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

Transmission solenoid power control relay controls vehicle power to all solenoids. Power is routed through the transmission solenoid power control relay (inside the TCM  ) to all transmission solenoids. If the power circuit to the transmission solenoids or the transmission solenoid power control relay fails open, all solenoids are failed electrically OFF. Check for open, short to ground or the transmission connector disconnected. The transmission solenoid power control relay disables power to the transmission solenoids when certain transmission DTCs are set.

NOTE: Without a voltage signal return to the TCM  , the transmission solenoid power control relay is commanded OFF. By using a fused jumper between a transmission solenoid control circuit and the signal return circuit, the transmission solenoid power control relay circuit supplies power to the transmission solenoids when the ignition is cycled from OFF to ON. Do not use a solenoid control circuit that may be at fault, refer to DTC CHARTS  for a fault listing.
