Code B2737 Description

The Pedestrian Protection Satellite Sensors perform internal self-tests and communicate the sensors status using power supplied by the Occupant Restraint Controller (ORC). The sensor communicates this internal failure message using the sensor signal circuit. If the scan tool shows this Diagnostic Trouble Code (DTC) has a Stored history of setting then the PPS Sensor is to be replaced.
This DTC sets when the ORC receives notification of a self test failure within the impact sensor within 100 ms for continuous test and 1 second for startup test. Once set, this DTC is latched for the entire ignition cycle or until the clear faults scan tool command is used, depending on the specific condition that sets the DTC.

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.
