About B1607

B1607 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.

When B1607 is stored, the module has detected an electrical-circuit fault in the wiring, connector, or driver associated with the named component.

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.

B1607 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 B1607 code indicates a circuit failure on the illuminated entry input to the Body Control Module (BCM), which on many Ford applications is referred to as the Generic Electronic Module (GEM). The illuminated entry input is the signal line the module monitors to decide when to switch on the interior courtesy and dome lamps, and it is driven by the door ajar switches, the courtesy lamp control, and on most models the remote keyless entry receiver. The module sets B1607 when it detects that this input is held in an invalid state, such as an open circuit, a short to ground, or a short to batter...
