U0171 Chrysler Code - Lost Communication With Up-Front Right Satellite Acceleration Sensor

Quick Answer

The impact 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. Common causes include Faulty Right Front Impact Sensor, Right Front Impact Sensor harness is open or shorted, Right Front Impact Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code U0171 Chrysler Description

The impact 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. This Diagnostic Trouble Code (DTC) sets when the ORC no longer receives the notification of the status update from the impact sensor. Once set, this DTC is latched for the entire ignition cycle.

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.
