About B1611

B1611 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 B1611 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.

B1611 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 B1611 code is set by the Generic Electronic Module (GEM) on Ford vehicles when an electrical fault is detected in the rear wiper mode select switch circuit. This switch communicates the driver selected rear wiper mode (off, intermittent, on, wash) to the GEM, which then activates the rear wiper motor accordingly. The GEM monitors the switch input lines and stores this code when it detects an open circuit, short to ground, or short to power on the switch wiring. When this code is set, the rear wiper may operate erratically, fail to respond to switch inputs, run continuously, or stop working...
