About B1659

B1659 is a manufacturer-specific body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1659 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.

B1659 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

B1659 is a body circuit fault stored by the seat control module (or body control module on integrated systems) when it detects an electrical failure in the driver front seat cushion up motor circuit. The seat module supplies switched battery voltage to the motor when the operator commands the front of the seat cushion to raise, then monitors the feedback to confirm correct circuit operation. The code typically sets when the module sees an open circuit, a short to ground, or a short to battery on the motor command line, or when the commanded actuation produces no expected current draw.
