3. Diagnostic Trouble Codes (DTCs)
If a scanner is plugged into the On-Board Diagnostics (OBD-II) port, particular codes will appear. Typical codes for Dodge Ram air bag concerns include:
- 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 aspects can result in the breakdown of an airbag sensing unit in a Dodge Ram 1500. Offered the truck's use in demanding environments, environmental aspects typically play a big role.
- Corrosion: Because front impact sensing units are situated near the grille and frame, they are exposed to roadway salt, moisture, and debris. Over time, the electrical connectors can wear away, breaking the circuit.
- Minor Collisions: Even a little "fender bender" that doesn't deploy the airbags can harm the internal parts of a sensor, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leak (typical in older designs with dripping 3rd brake lights or sunroof drains pipes), moisture can leak into the B-pillar sensors or the ORC module under the center console.
- Electrical wiring Issues: The circuitry utilizes under the seats are vulnerable to being pinched or disconnected when seats are moved often, often impacting the Occupant Classification Sensor.
Historical Recalls and Safety Concerns
Owners of the Dodge Ram 1500 ought to be mindful of historical recalls related to the air bag system. Fiat Chrysler Automobiles (FCA) has issued a number of recalls throughout the years to attend to software application and hardware defects.
- ORC Module Software (2013-2016 Models): A considerable recall was released for these years due to the fact that a software application error could prevent the side airbags and seatbelt pretensioners from releasing during a rollover.
- Clock Spring Failures: While not a sensing unit itself, the clock spring in the steering wheel frequently fails in older Rams, breaking the connection to the driver-side airbag and triggering the SRS light.
- Sensor Housing Cracks: Some designs dealt with issues where the plastic housing of the impact sensors would split, permitting moisture to go into and short-circuit the system.
To check if a particular Dodge Ram 1500 is impacted by a recall, owners ought to check out the Mopar or NHTSA website and enter their car's 17-digit VIN.
Medical diagnosis and Repair: What to Expect
Diagnosing an airbag issue is not a typical DIY task for the typical lover since it needs a specific scan tool efficient in checking out SRS/ABS codes (standard inexpensive OBD-II scanners frequently just check out engine codes).
The Diagnostic Process
- Scanning: A specialist recovers the particular DTC to identify which sensing unit is failing.
- Visual Inspection: Checking the electrical wiring harness and the sensing unit's physical condition for signs of deterioration or effect.
- Circuit Testing: Using a multimeter to check for continuity in the electrical wiring (Caution: This need to be finished with the battery disconnected to prevent accidental implementation).
Replacement Steps
If a sensor is verified faulty, replacement follows these general actions:
- Power Down: The battery should be disconnected, and the system needs to sit for a minimum of 10-- 15 minutes to allow the capacitors to discharge.
- Accessing the Sensor: Depending on the sensor, this may include removing the front grille, interior trim panels, or the front seats.
- Component Swap: The old sensor is unbolted, and the new OEM (Original Equipment Manufacturer) sensing unit is installed.
- System Reset: The professional clears the codes and performs a "proxy alignment" or system calibration to guarantee the brand-new sensing unit is recognized by the ORC module.
