B1692 — Autolamp Delay Circuit Short To Ground

System: Body  |  Type: Manufacturer-Specific  |  Make: Ford

About B1692

B1692 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 B1692 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.

B1692 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 B1692 code is set when the Body Control Module (BCM) or Light Control Module detects that the autolamp delay control input is shorted to ground. The autolamp delay circuit normally provides a positive signal voltage that varies with the position of the dash mounted delay control, and the BCM continuously compares that voltage against expected ranges. When the input pin reads at or near 0V regardless of switch position, the BCM concludes there is a short to ground in the wiring or within the switch itself. The result is that the autolamp delay function is disabled, and the headlights either...
