About B1610

B1610 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 B1610 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

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.

B1610 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 B1610 code indicates that the Body Control Module (BCM), which on many Ford applications is referred to as the Generic Electronic Module (GEM), has detected a short to ground on the illuminated entry input circuit. The illuminated entry input is the signal line the module monitors to know when to switch on the interior courtesy and dome lamps, and it is fed by the door ajar switches, the courtesy lamp control, and on most models the remote keyless entry receiver. With a short to ground present, the input is held permanently at near 0V regardless of switch state, so the module either sees t...
