Code U300E Ford Description
Internally to the ABS module, the ignition voltage supply circuit is used as a redundant back up for the battery voltage supply circuit in case the battery voltage supply circuit is interrupted. If the battery voltage supply circuit is interrupted, the ABS module immediately shuts off and does not enter the power latch mode. The module uses the power latch mode to write certain parameters (such as learned offsets numbers) to non-volatile memory. At the beginning of each ignition cycle, a counter value is increased by 1 after a specified vehicle speed has been reached and a specified time has elapsed. When the ABS module enters the power latch mode, this counter is reset to 0.
