DTC B2001 Short to GND in Seat Belt Motor RH Circuit: Description

WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.

The seat belt control ECU receives information from the distance control ECU using CAN communication and tightens the seat belt by operating the motor in the front seat outer belt assembly RH.

CAUTION: The pretensioner is built into the front seat outer belt assembly RH. Be sure to follow the correct inspection procedure, as failure to follow the correct procedure (such as inspection of incorrect connectors) may deploy the pretensioner.
