About B10E5

B10E5 is a manufacturer-specific body diagnostic trouble code recorded for Ford vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B10E5 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Body Control Module (BCM) on Ford vehicles is responsible for waking the Powertrain Control Module (PCM) when a driver action or a network event requires the engine controller to become active. The BCM asserts a dedicated wake up line, or sends a wake up frame on the vehicle CAN or LIN network, and then expects the PCM to respond by coming online and acknowledging the wake up within a defined window. DTC B10E5 with failure type 15 is logged when the BCM detects that this wake up circuit is either open or has been shorted to battery voltage during the wake attempt, preventing the PCM from b...
