About B1652

B1652 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 B1652 is stored, the module has detected an open (broken or disconnected) electrical path 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.

B1652 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 B1652 fault code indicates an open circuit condition has been detected by the Driver Seat Module (DSM) or Body Control Module (BCM) on the driver seat recline backward control circuit. This circuit drives the electric motor that tilts the seat backrest rearward when the driver operates the recline switch on power adjustable seats. The seat module energises the recline backward output and uses voltage feedback or load monitoring to confirm a complete electrical path through the harness and motor windings, setting B1652 specifically as an open when no current flows during the active command....
