DTC B1940: Short in Selectable Force Limiter Squib RH Circuit; DTC B1941: Open in Selectable Force Limiter Squib RH Circuit; DTC B1942: Short to GND in Selectable Force Limiter Squib RH Circuit; DTC B1943: Short to B+ in Selectable Force Limiter Squib RH Circuit [12/2019 - 11/2023]: Description

The selectable force limiter squib RH circuit consists of the airbag sensor assembly and front seat outer belt assembly RH.

The airbag sensor assembly uses this circuit to deploy the selectable force limiter when deployment conditions are met.

These DTCs are stored when a malfunction is detected in the selectable force limiter squib RH circuit.
