Engine Running Load Shed
WARNING: This page is about a different car, the 2022 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
When the BCM and/or PSCM voltage is low, with the engine running, a message is sent by the BCM to either minimize or shut down the climate controlled seats, rear defrost, heated mirrors and DATC blower motor to improve system voltage. Under this condition, the IPC message center displays either LOW BATTERY LESS FEATURES (base message center) or Electrical Power Saver Active. Some Features Turned Off See Manual to notify the driver that battery protection actions are active.
For more information on message center messages, Refer to the Owner's Literature or Refer to: Warning Chimes - System Operation and Component Description .
There are 3 states of engine running load shed:
| Load Shed State | Entry Conditions | Impact to Features | Clear Conditions |
|---|---|---|---|
| Load shed 1 | If power source (alternator/DCDC) is fully saturated in combination with low battery voltage and low battery SOC. | These loads are incrementally reduced (if equipped): Heated steering wheel and climate controlled seats. These loads are turned off (if equipped): smart trailer tow battery charge, heated mirrors, any climate features. | Power source no longer saturated and battery voltage has recovered. |
| Load shed 2 transient | PSCM indicating reduced voltage and increased current. System voltage less than 11 volts. | If equipped, climate controlled seats are disabled, but the indicators remain illuminated. If equipped, rear defrost and heated mirrors are disabled, but the indicator remain illuminated. |
Voltage to the BCM is greater than 12.5 volts. |
| Load shed 2 continuous | Load Shed 2 Transient condition present for up to 60sec. | If equipped, any climate features are disabled and indicators are off. If equipped with DATC, the blower motor is reduced to 50% speed. If equipped, DC/AC inverter (AC powerpoint) is disabled. The IPC message center displays "Electrical Power Saver Active. Some Features Turned Off See Manual. |
Voltage to the BCM is greater than 12.4 volts for more than 60 seconds. |
