3. Diagnostic Trouble Codes (DTCs)
If a scanner is plugged into the On-Board Diagnostics (OBD-II) port, particular codes will appear. Common codes for Dodge Ram air bag concerns consist of:
- B0001: Driver Frontal Stage 1 Deployment Control.
- B1B02: Driver Airbag Squib 2 Circuit Low.
- B1B06: Passenger Airbag Squib 2 Circuit Low.
- B2207: Occupant Restraint Controller Internal.
Causes of Airbag Sensor Failure
A number of factors can lead to the malfunction of an airbag sensing unit in a Dodge Ram 1500. Offered Dodge Ram 1500 Airbags Order Online in requiring environments, environmental aspects often play a big function.
- Corrosion: Because front impact sensors are situated near the grille and frame, they are exposed to road salt, moisture, and debris. With time, the electrical connectors can wear away, breaking the circuit.
- Minor Collisions: Even a little "fender bender" that does not release the airbags can damage the internal elements of a sensor, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leakage (typical in older models with leaking third brake lights or sunroof drains), moisture can leak into the B-pillar sensors or the ORC module under the center console.
- Circuitry Issues: The electrical wiring utilizes under the seats are susceptible to being pinched or detached when seats are moved regularly, frequently affecting the Occupant Classification Sensor.
Historical Recalls and Safety Concerns
Owners of the Dodge Ram 1500 ought to understand historical recalls connected to the air bag system. Fiat Chrysler Automobiles (FCA) has issued numerous remembers for many years to resolve software application and hardware problems.
- ORC Module Software (2013-2016 Models): A significant recall was issued for these years due to the fact that a software application error might prevent the side airbags and seatbelt pretensioners from releasing throughout a rollover.
- Clock Spring Failures: While not a sensing unit itself, the clock spring in the guiding wheel often fails in older Rams, breaking the connection to the driver-side airbag and setting off the SRS light.
- Sensor Housing Cracks: Some designs faced problems where the plastic housing of the effect sensors would split, permitting wetness to go into and short-circuit the unit.
To check if a particular Dodge Ram 1500 is impacted by a recall, owners ought to check out the Mopar or NHTSA site and enter their lorry's 17-digit VIN.
Diagnosis and Repair: What to Expect
Diagnosing an air bag issue is not a common DIY task for the average enthusiast because it requires a specialized scan tool capable of checking out SRS/ABS codes (standard low-cost OBD-II scanners frequently only check out engine codes).
The Diagnostic Process
- Scanning: A service technician obtains the particular DTC to recognize which sensing unit is failing.
- Visual Inspection: Checking the circuitry harness and the sensing unit's physical condition for signs of rust or impact.
