Code B2768 Description

The right side impact pressure sensor 4 is located in the first row door. The impact pressure sensors perform their own self test using power supplied by the Occupant Restraint Controller (ORC) then communicate this status back to the ORC with periodic updates. The repair of this fault condition involves verifying the integrity of the wiring between the ORC and the sensor. The ORC continuously communicates with the Right Side Impact (Pressure) Sensor 4 over the sensor signal circuit. The sensor communication and on board diagnostics are powered by the ORC signal.
This code will set, if the ORC and the Right Side Impact (Pressure) Sensor 4 do not establish and maintain valid data communications. The Diagnostic Trouble Code (DTC) will become Active after the fault has set for 9 seconds. The DTC will go to Stored after the ORC to Right Side Impact (Pressure) Sensor 4 communication has recovered for 4 seconds.

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.
