Code B1765 Hyundai Description

In order to make normal activation of the airbag system, Supplemental Restraints System Control Module (SRSCM) detects a Diagnostic Trouble Code (DTC) for the Passenger side Body Detection System. If the seat is occupied, Body Sense Sensor detects how passenger weighs and send a signal to the Airbag Control Unit (ACU) via Controller Area Network (CAN). The ACU recognizes the signal as 3 (three) different classifications; that is, 0 (Empty), 1 (Small), 2 (Large). With these signal, ACU determines whether it needs to deploy PAB (Passenger Airbag) or not.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
