About B1529

B1529 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 B1529 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.

B1529 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 Memory Set Switch is a momentary push button typically located on the driver door panel that allows the operator to save and recall preset memory positions for the seat, mirrors, and on some platforms the steering column and pedals. The Body Control Module or dedicated Memory Seat Module monitors the switch input circuit and sets DTC B1529 when battery voltage is detected on the switch signal wire when the module expects it to be at rest (either pulled high through an internal resistor or sitting at ground depending on platform). A short to battery on this circuit forces the input permanen...
