About B1613

B1613 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 B1613 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.

B1613 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 B1613 code is set by the Generic Electronic Module (GEM) on Ford vehicles when the rear wiper mode select switch input wiring is shorted to battery voltage. The rear wiper switch is normally pulled to a defined reference state by the GEM, so unexpected battery voltage on this input is recognised as an electrical fault. The most common cause is harness damage where a switch wire has rubbed through to a power feed, or moisture bridging pins inside a connector. When this code is set, the rear wiper may run continuously, fail to respond to switch inputs, or operate in the wrong mode regardless...
