B1740 P-SIS Front-Driver Short to Ground - General Information

Component Location





Component Location

Pressure-Side Impact Sensor and Side Impact Sensor are installed in the left and the right side of front door and in the lower of B-pillar respectively.
Unlike the conventional acceleration sensor such as DSIS, PSIS, the Pressure Sensor senses an air pressure changes as door volume changes due to a deformation of door during crash event
SRSCM receives both signals from Pressure SIS / D or PSIS and calculates the crash severity along with internal safing sensor signal. SRSCM issues the deployment of side / curtain airbags if combined crash signals meet the crash severity level of side crash discrimination algorithm in side of SRSCM

NOTE:
At inspecting the pressure sensor, keep the door airtight for an exact measuring.

DTC Description

The SRSCM sets DTC B1740 if there is a short to ground in Pressure-Side Impact (Driver) harness.
