U11F0 Dodge Code - Lost Communication With Left Impact Pressure 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 Left Impact Pressure Sensor, Left Impact Pressure Sensor harness is open or shorted, Left Impact Pressure 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 U11F0 Dodge 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. A short to voltage fault on the door pressure sensor wiring can cause a loss of communication side-impact code to set and the possible replacement of a good side impact sensor. The door pressure sensor is hardwired to the side impact sensor which is hard-wired to the ORC creating a daisy chain circuit. The short to battery fault in a loss of communication or internal circuit failure of the door pressure sensor can cause the side impact sensor on the same side to set a loss of communication code. This code will set, if the ORC and the Driver Door Pressure Sensor do not establish and maintain valid data communications. The Diagnostic Trouble Code (DTC) will become Active after the fault has set for a minimum of 2.5 seconds. The DTC will go to Stored after the ORC to Driver Door Pressure Sensor communication fault has been removed or the suspect pressure sensor has been replaced for 2.5 seconds. The Multifunction Indicator Lamp (MIL) will set in the instrument cluster.

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.
