This guide provides a thorough look at the Dodge Ram 1500 air bag sensing unit system, covering its components, typical concerns, and the required actions to make sure the lorry stays a safe fortress for its travelers.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern lorries like the Dodge Ram 1500 make use of a Supplemental Restraint System (SRS). This system is not planned to replace seat belts however to operate in tandem with them. The airbag sensing units act as the "nervous system" of the lorry. These parts are strategically put throughout the truck to spot sudden deceleration or physical impact.
When an impact happens, the sensors send an electrical signal to the Occupant Restraint Control (ORC) module, which acts as the "brain" of the SRS. The ORC assesses the seriousness of the effect and determines whether to deploy the airbags and pretension the seat belts. Dodge Ram 1500 Airbags Cost occurs within milliseconds-- faster than the blink of an eye.
Types of Airbag Sensors in the Dodge Ram 1500
The Ram 1500 is geared up with various sensors, each serving a specific purpose based upon the direction and kind of effect.
| Sensor Type | Main Location | Function |
|---|---|---|
| Front Impact Sensors | Mounted on the radiator assistance or front frame rails. | Spots head-on crashes and activates front airbags. |
| Side Impact Sensors | Found inside the doors or B-pillars. | Activates side-curtain and seat-mounted airbags throughout T-bone accidents. |
| Rollover Sensors | Usually integrated into the ORC module (center console location). | Identifies the vehicle's pitch and roll angle to release side curtains in a rollover. |
| Occupant Classifcation Sensor (OCS) | Inside the passenger seat cushion. | Identifies the weight of the guest to adjust or disable airbag deployment for kids. |
Typical Symptoms of a Failing Airbag Sensor
When an air bag sensor stops working, the vehicle's computer system usually detects the abnormality instantly. Because the SRS is essential for safety, the vehicle will signal the motorist through numerous signs.
1. The SRS Warning Light
The most common sign is the illumination of the "Airbag" or "SRS" light on the instrument cluster. Under normal conditions, this light must switch on briefly when the ignition is begun and after that vanish. If it stays lit or flashes while driving, the system has found a fault and has likely disabled the airbag system.
2. Audible Chimes
In lots of Dodge Ram models, a persistent warning light is accompanied by a chime or "ping" noise when the lorry is started. This is developed to guarantee the chauffeur does not neglect the visual warning on the dashboard.
3. Diagnostic Trouble Codes (DTCs)
If a scanner is plugged into the On-Board Diagnostics (OBD-II) port, specific codes will appear. Typical codes for Dodge Ram airbag 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
Several aspects can lead to the breakdown of an airbag sensor in a Dodge Ram 1500. Provided Dodge Ram 1500 Airbags Store in requiring environments, ecological factors often play a large function.
- Corrosion: Because front impact sensing units lie near the grille and frame, they are exposed to roadway salt, moisture, and particles. With time, the electrical adapters can wear away, breaking the circuit.
- Minor Collisions: Even a small "fender bender" that does not deploy the airbags can harm the internal elements of a sensor, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leakage (common in older designs with leaking 3rd brake lights or sunroof drains pipes), wetness can leak into the B-pillar sensors or the ORC module under the center console.
- Wiring Issues: The circuitry harnesses under the seats are susceptible to being pinched or detached when seats are moved regularly, often impacting the Occupant Classification Sensor.
Historic Recalls and Safety Concerns
Owners of the Dodge Ram 1500 need to know historical recalls connected to the air bag system. Fiat Chrysler Automobiles (FCA) has actually provided a number of recalls over the years to attend to software and hardware flaws.
- ORC Module Software (2013-2016 Models): A significant recall was issued for these years due to the fact that a software mistake could avoid the side airbags and seat belt pretensioners from releasing during a rollover.
- Clock Spring Failures: While not a sensor itself, the clock spring in the guiding wheel typically stops working in older Rams, breaking the connection to the driver-side air bag and triggering the SRS light.
- Sensing Unit Housing Cracks: Some models faced problems where the plastic housing of the effect sensors would split, enabling wetness to get in and short-circuit the unit.
To inspect if a specific Dodge Ram 1500 is affected by a recall, owners need to go to the Mopar or NHTSA website and enter their automobile's 17-digit VIN.
Diagnosis and Repair: What to Expect
Identifying an airbag concern is not a typical DIY task for the average enthusiast because it requires a specialized scan tool efficient in checking out SRS/ABS codes (basic low-cost OBD-II scanners frequently only read engine codes).
The Diagnostic Process
- Scanning: A specialist obtains the particular DTC to recognize which sensing unit is failing.
- Visual Inspection: Checking the wiring harness and the sensor's physical condition for indications of deterioration or effect.
- Circuit Testing: Using a multimeter to look for continuity in the electrical wiring (Caution: This must be finished with the battery disconnected to prevent unintentional deployment).
Replacement Steps
If a sensor is validated faulty, replacement follows these general steps:
- Power Down: The battery must be disconnected, and the system must sit for a minimum of 10-- 15 minutes to enable the capacitors to discharge.
- Accessing the Sensor: Depending on the sensor, this might include eliminating the front grille, interior trim panels, or the front seats.
- Component Swap: The old sensing unit is unbolted, and the brand-new OEM (Original Equipment Manufacturer) sensor is set up.
- System Reset: The specialist clears the codes and performs a "proxy alignment" or system calibration to ensure the new sensing unit is recognized by the ORC module.
