About B1660

B1660 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 B1660 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.

B1660 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

B1660 is set by the seat control module when it detects an open circuit condition on the driver front seat cushion up motor command line. Unlike a generic circuit failure code, this entry specifically identifies that the module has lost electrical continuity through the motor circuit, meaning current cannot flow when the up command is issued. The module typically detects this condition by monitoring for expected current draw on the drive output and logging the code when no load is sensed during commanded actuation. When this code is present the front of the driver's seat cushion will not raise...
