About B1615

B1615 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 B1615 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.

B1615 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 B1615 code is set by the Generic Electronic Module (GEM) on Ford vehicles when an electrical fault is detected on the rear wiper disable switch input circuit. The rear wiper disable switch is typically a tailgate or rear hatch ajar contact, or a glass open contact, that the GEM uses to suspend rear wiper operation when the rear glass or hatch is not in the secured position. A circuit failure here means the GEM cannot reliably read whether the disable input is open or closed, so a fault is logged. When this code is set, the rear wiper may refuse to operate, may run when it should be inhibit...
