About B2342

B2342 is a generic (obd-ii standard) body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B2342 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.

Because B2342 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The B2342 code identifies an open circuit fault on the seat switch reference voltage positive common line. This is the 5V reference shared across all position switches (fore/aft, height, tilt, recline, lumbar) inside the power seat switch pack. The seat memory module or driver door module supplies the reference and senses each switch closure through pull up resistors. When the reference common circuit is open, every switch input collapses simultaneously and no seat positioning can be commanded. The driver typically notices that none of the power seat functions respond and that scan tool data s...
