A 2.0kW Pro Power Onboard inverter system is identified by: DCACA inverter assembly being located in the cabin under the rear seat on the left side of the vehicle. To correct the condition using the latest level of Ford Diagnosis and Repair System (FDRS), reprogram the DCACA module. For claiming use causal part number 19G317 and applicable labor times from Section 10 of the Service Labor Times Standard (SLTS) Manual.
