About B1527

B1527 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 B1527 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.

B1527 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 Body Control Module or dedicated Memory Seat Module monitors the switch input circuit and sets DTC B1527 when an electrical fault is detected, such as an open circuit, a short to ground, or a short to voltage on the switch signal wire. When this fault is active the operator cannot save or recall stored memory positions, although manual seat adjustment cont...
