This guide supplies an in-depth take a look at the Dodge Ram 1500 air bag sensor system, covering its components, common problems, and the required steps to ensure the lorry stays a safe fortress for its guests.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern automobiles like the Dodge Ram 1500 make use of a Supplemental Restraint System (SRS). This system is not intended to change seat belts however to operate in tandem with them. The airbag sensing units serve as the "nerve system" of the lorry. These components are tactically put throughout the truck to detect sudden deceleration or physical effect.
When an impact takes place, the sensors send out an electrical signal to the Occupant Restraint Control (ORC) module, which works as the "brain" of the SRS. Dodge Ram 1500 Airbags Official Website examines the seriousness of the impact and figures out whether to release the airbags and pretension the seatbelts. This entire procedure occurs within milliseconds-- faster than the blink of an eye.
Kinds Of Airbag Sensors in the Dodge Ram 1500
The Ram 1500 is geared up with different sensing units, each serving a specific function based on the direction and kind of effect.
| Sensor Type | Main Location | Function |
|---|---|---|
| Front Impact Sensors | Mounted on the radiator support or front frame rails. | Spots head-on accidents and activates front airbags. |
| Side Impact Sensors | Found inside the doors or B-pillars. | Triggers side-curtain and seat-mounted airbags during T-bone mishaps. |
| Rollover Sensors | Typically incorporated into the ORC module (center console area). | Detects the car's pitch and roll angle to release side curtains in a rollover. |
| Occupant Classifcation Sensor (OCS) | Inside the passenger seat cushion. | Figures out the weight of the passenger to change or disable air bag release for children. |
Common Symptoms of a Failing Airbag Sensor
When an air bag sensing unit fails, the car's computer system usually detects the abnormality instantly. Since the SRS is crucial for security, the automobile will notify the chauffeur through several signs.
1. The SRS Warning Light
The most typical sign is the illumination of the "Airbag" or "SRS" light on the instrument cluster. Under typical conditions, this light needs to turn on briefly when the ignition is started and then vanish. If it stays lit or flashes while driving, the system has actually detected a fault and has likely handicapped the airbag system.
2. Audible Chimes
In many Dodge Ram models, a persistent warning light is accompanied by a chime or "ping" sound when the vehicle is begun. This is developed to guarantee the motorist does not overlook the visual warning on the control panel.
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 airbag problems 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 factors can cause the breakdown of an airbag sensing unit in a Dodge Ram 1500. Given the truck's usage in demanding environments, ecological factors typically play a large role.
- Corrosion: Because front impact sensing units lie near the grille and frame, they are exposed to roadway salt, wetness, and particles. Gradually, 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 components of a sensor, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leakage (common in older designs with dripping third brake lights or sunroof drains), wetness can leak into the B-pillar sensing units or the ORC module under the center console.
- Electrical wiring Issues: The circuitry harnesses under the seats are prone to being pinched or disconnected when seats are moved often, typically impacting the Occupant Classification Sensor.
Historic Recalls and Safety Concerns
Owners of the Dodge Ram 1500 need to know historic recalls associated with the air bag system. Fiat Chrysler Automobiles (FCA) has actually issued a number of recalls over the years to resolve software and hardware problems.
- ORC Module Software (2013-2016 Models): A significant recall was released for these years since a software application mistake 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 often fails in older Rams, breaking the connection to the driver-side airbag and triggering the SRS light.
- Sensor Housing Cracks: Some designs faced issues where the plastic real estate of the impact sensors would break, enabling wetness to enter and short-circuit the system.
To examine if a particular Dodge Ram 1500 is impacted by a recall, owners should check out the Mopar or NHTSA website and enter their lorry's 17-digit VIN.
Diagnosis and Repair: What to Expect
Identifying an airbag issue is not a typical DIY job for the average enthusiast since it needs a specialized scan tool efficient in checking out SRS/ABS codes (basic low-cost OBD-II scanners often only check out engine codes).
The Diagnostic Process
- Scanning: A service technician obtains the specific DTC to recognize which sensing unit is failing.
- Visual Inspection: Checking the circuitry harness and the sensing unit's physical condition for indications of rust or effect.
- Circuit Testing: Using a multimeter to look for connection in the wiring (Caution: This need to be done with the battery disconnected to avoid unintentional implementation).
Replacement Steps
If a sensing unit is validated malfunctioning, replacement follows these general steps:
- Power Down: The battery needs to be detached, and the system must sit for a minimum of 10-- 15 minutes to enable the capacitors to release.
- Accessing the Sensor: Depending on the sensor, this might include getting rid of the front grille, interior trim panels, or the front seats.
- Element Swap: The old sensing unit is unbolted, and the new OEM (Original Equipment Manufacturer) sensing unit 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 acknowledged by the ORC module.
