ELECTRIC MOTOR/TRANSAXLE DIAGNOSIS

Electric Motor/Transaxle
The Ranger EV uses a three-phase 90-hp electric motor with an
integrated planetary gear transmission. The unit is not field
serviceable, and is only serviced as an assembly.
To determine if a component of the motor/transaxle assembly is the
source of a concern, Ford has developed the Electric Motor/
Transaxle Test Box.
This tool can test:
•
motor speed sensor operation.
•
motor temperature sensor operation.
•
oil pressure sensor operation.
•
oil pump operation.
Refer to the appropriate pinpoint tests for Electric Motor/
Transaxle Test Box diagnostic procedures.
