This guide supplies a thorough look at the Dodge Ram 1500 airbag sensing unit system, covering its elements, typical concerns, and the needed steps to make sure the vehicle remains a safe fortress for its travelers.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern vehicles like the Dodge Ram 1500 use a Supplemental Restraint System (SRS). This system is not intended to replace seat belts but to work in tandem with them. The air bag sensing units act as the "worried system" of the automobile. These components are strategically positioned throughout the truck to detect unexpected deceleration or physical effect.
When an impact takes place, the sensors send out an electrical signal to the Occupant Restraint Control (ORC) module, which serves as the "brain" of the SRS. The ORC evaluates the intensity of the impact and identifies whether to deploy the airbags and pretension the seat belts. This whole procedure happens 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 sensors, each serving a particular function based on the instructions and kind of effect.
| Sensing unit Type | Primary Location | Function |
|---|---|---|
| Front Impact Sensors | Installed on the radiator assistance or front frame rails. | Discovers head-on crashes and triggers front airbags. |
| Side Impact Sensors | Located inside the doors or B-pillars. | Triggers side-curtain and seat-mounted airbags throughout T-bone accidents. |
| Rollover Sensors | Typically integrated into the ORC module (center console area). | Finds the vehicle's pitch and roll angle to release side drapes in a rollover. |
| Occupant Classifcation Sensor (OCS) | Inside the passenger seat cushion. | Figures out the weight of the guest to adjust or disable air bag release for kids. |
Typical Symptoms of a Failing Airbag Sensor
When an air bag sensor stops working, the vehicle's computer system generally identifies the abnormality instantly. Because the SRS is crucial for safety, the automobile will inform the motorist through numerous indications.
1. The SRS Warning Light
The most common sign is the lighting of the "Airbag" or "SRS" light on the instrument cluster. Under normal conditions, this light should turn on briefly when the ignition is begun and after that disappear. If it stays lit or flashes while driving, the system has actually found a fault and has likely handicapped the airbag system.
2. Audible Chimes
In many Dodge Ram designs, a consistent caution light is accompanied by a chime or "ping" noise when the automobile is begun. This is created to guarantee the chauffeur does not ignore 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. 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
Several factors can lead to the malfunction of an air bag sensing unit in a Dodge Ram 1500. Given the truck's usage in demanding environments, environmental elements typically play a large function.
- Corrosion: Because front impact sensing units are situated near the grille and frame, they are exposed to road salt, wetness, and debris. With time, the electrical adapters can wear away, breaking the circuit.
- Minor Collisions: Even a small "minor car accident" that doesn't release the airbags can damage the internal parts of a sensor, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leak (typical in older models with leaking third brake lights or sunroof drains pipes), wetness can permeate into the B-pillar sensors or the ORC module under the center console.
- Electrical wiring Issues: The electrical wiring harnesses under the seats are vulnerable to being pinched or disconnected when seats are moved frequently, frequently affecting the Occupant Classification Sensor.
Historic Recalls and Safety Concerns
Owners of the Dodge Ram 1500 ought to be aware of historical recalls associated with the air bag system. Fiat Chrysler Automobiles (FCA) has actually issued several remembers throughout the years to address software application and hardware defects.
- ORC Module Software (2013-2016 Models): A significant recall was provided for these years since a software application mistake might avoid the side airbags and seatbelt pretensioners from deploying throughout a rollover.
- Clock Spring Failures: While not a sensor itself, the clock spring in the guiding wheel frequently fails in older Rams, breaking the connection to the driver-side air bag and setting off the SRS light.
- Sensor Housing Cracks: Some designs faced issues where the plastic real estate of the impact sensing units would break, enabling wetness to enter and short-circuit the unit.
To inspect if a specific Dodge Ram 1500 is affected by a recall, owners should go to the Mopar or NHTSA site and enter their car's 17-digit VIN.
Diagnosis and Repair: What to Expect
Diagnosing an airbag problem is not a common DIY job for the average lover due to the fact that it requires a specific scan tool capable of reading SRS/ABS codes (standard low-cost OBD-II scanners often just read engine codes).
The Diagnostic Process
- Scanning: A service technician obtains the specific DTC to identify which sensor is stopping working.
- Visual Inspection: Checking the circuitry harness and the sensor's physical condition for indications of rust or effect.
- Circuit Testing: Using a multimeter to look for connection in the wiring (Caution: This should be done with the battery disconnected to prevent unexpected release).
Replacement Steps
If a sensor is verified defective, replacement follows these general steps:
- Power Down: The battery must be disconnected, and the system should sit for at least 10-- 15 minutes to allow the capacitors to release.
- 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 sensing unit is unbolted, and the brand-new OEM (Original Equipment Manufacturer) sensing unit is set up.
- System Reset: The service technician clears the codes and carries out a "proxy alignment" or system calibration to make sure the brand-new sensing unit is acknowledged by the ORC module.
