LESSON 5: DIAGNOSIS
Emergency Power Off (EPO)
In the event an unsafe condition occurs that will disable an interlock or if the inertia switch is triggered, an EPO
signal will be sent to disable all high voltage loads.
•
Can be set by IAA, BCM, or TIM.
•
An EPO event will be accompanied by multiple instrument cluster lights illuminating and the vehicle shutting
down.
•
If an EPO occurs, a DTC will be set that will aid you in locating the source of the concern. Refer to the Ranger
EV service publications for EPO diagnostic procedures.
