This guide provides an extensive appearance at the Dodge Ram 1500 airbag sensing unit system, covering its components, common concerns, and the necessary actions to ensure the lorry remains a safe fortress for its passengers.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern vehicles like the Dodge Ram 1500 make use of a Supplemental Restraint System (SRS). This system is not meant to replace seatbelts however to operate in tandem with them. The airbag sensing units act as the "nerve system" of the automobile. These elements are tactically put throughout the truck to discover abrupt deceleration or physical impact.
When an effect takes place, the sensing units send out an electrical signal to the Occupant Restraint Control (ORC) module, which works as the "brain" of the SRS. The ORC evaluates the seriousness of the impact and identifies whether to release the airbags and pretension the seat belts. This entire procedure happens within milliseconds-- faster than the blink of an eye.
Kinds Of Airbag Sensors in the Dodge Ram 1500
The Ram 1500 is equipped with different sensors, each serving a specific purpose based on the direction and kind of impact.
| Sensing unit Type | Main Location | Function |
|---|---|---|
| Front Impact Sensors | Installed on the radiator support or front frame rails. | Finds head-on accidents and triggers front airbags. |
| Side Impact Sensors | Found inside the doors or B-pillars. | Sets off side-curtain and seat-mounted airbags during T-bone accidents. |
| Rollover Sensors | Usually integrated into the ORC module (center console area). | Finds the lorry's pitch and roll angle to deploy side curtains in a rollover. |
| Occupant Classifcation Sensor (OCS) | Inside the traveler seat cushion. | Determines the weight of the passenger to adjust or disable airbag release for kids. |
Typical Symptoms of a Failing Airbag Sensor
When an air bag sensor fails, the automobile's computer system usually detects the anomaly right away. Since the SRS is important for safety, the automobile will notify the chauffeur through numerous signs.
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 then disappear. If it stays lit or flashes while driving, the system has discovered a fault and has likely disabled the air bag system.
2. Audible Chimes
In numerous Dodge Ram designs, a persistent caution light is accompanied by a chime or "ping" sound when the vehicle is begun. This is designed to make sure the chauffeur does not ignore the visual caution 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 issues 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
Numerous aspects can result in the malfunction of an airbag sensing unit in a Dodge Ram 1500. Offered the truck's usage in demanding environments, ecological elements typically play a large function.
- Deterioration: Because front effect sensing units lie near the grille and frame, they are exposed to roadway salt, wetness, and particles. Over time, the electrical connectors can rust, breaking the circuit.
- Minor Collisions: Even a small "minor car accident" that does not deploy the airbags can damage the internal parts of a sensing unit, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leak (common in older designs with dripping 3rd brake lights or sunroof drains pipes), wetness can permeate into the B-pillar sensing units or the ORC module under the center console.
- Wiring Issues: The wiring utilizes under the seats are vulnerable to being pinched or disconnected when seats are moved often, frequently affecting the Occupant Classification Sensor.
Historic Recalls and Safety Concerns
Owners of the Dodge Ram 1500 need to be mindful of historical recalls associated with the airbag system. Fiat Chrysler Automobiles (FCA) has actually issued several remembers throughout the years to attend to software application and hardware defects.
- ORC Module Software (2013-2016 Models): A significant recall was provided for these years because a software error could prevent the side airbags and seatbelt pretensioners from deploying during a rollover.
- Clock Spring Failures: While not a sensing unit itself, the clock spring in the steering wheel frequently stops working in older Rams, breaking the connection to the driver-side air bag and triggering the SRS light.
- Sensor Housing Cracks: Some designs faced concerns where the plastic housing of the effect sensing units would crack, enabling moisture to enter and short-circuit the system.
To examine if a particular Dodge Ram 1500 is impacted by a recall, owners ought to visit the Mopar or NHTSA site and enter their car's 17-digit VIN.
Diagnosis and Repair: What to Expect
Detecting an airbag issue is not a normal DIY task for the average enthusiast because it requires a customized scan tool capable of reading SRS/ABS codes (standard cheap OBD-II scanners typically just read engine codes).
The Diagnostic Process
- Scanning: A technician retrieves the specific DTC to determine which sensing unit is stopping working.
- Visual Inspection: Checking the electrical wiring harness and the sensor's physical condition for signs of deterioration or impact.
- Circuit Testing: Using a multimeter to examine for connection in the circuitry (Caution: This must be finished with the battery disconnected to prevent unintentional release).
Replacement Steps
If a sensing unit is confirmed malfunctioning, replacement follows these basic steps:
- Power Down: The battery should be disconnected, and the system should sit for at least 10-- 15 minutes to allow 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.
- Part Swap: The old sensing unit is unbolted, and the brand-new OEM (Original Equipment Manufacturer) sensor is installed.
- System Reset: The technician clears the codes and performs a "proxy positioning" or system calibration to make sure the new sensor is acknowledged by the ORC module.

Regularly Asked Questions (FAQ)
Can I drive my Dodge Ram with the airbag light on?
While the truck remains drivable, it is highly discouraged. When the SRS light is illuminated, the system remains in "fault mode," which usually suggests the airbags will not deploy in case of an accident. This significantly increases the threat of injury or death.
Where is the air bag sensing unit situated on a 2019+ Dodge Ram 1500?
The 5th-generation Ram (DT) has effect sensors situated behind the front bumper cover on the frame rails and side impact sensing units located in the lower part of the B-pillars and C-pillars.
Will a blown fuse trigger the airbag light to come on?
Yes. If the fuse accountable for the SRS or ORC module blows, the system will lose power and trigger the warning light. Examining Buy Dodge Airbags Online is typically the first and most inexpensive diagnostic step.
Do I need to use OEM parts for air bag sensing units?
It is strongly suggested to use OEM Mopar sensing units. The SRS is a life-saving system calibrated particularly to the lorry's crush zones and weight. Aftermarket sensors might not have the exact same precision or response times, possibly resulting in failure during a crash.
Can water leaks activate the airbag light in a Ram 1500?
Yes. A typical concern in Ram trucks is a leaking 3rd brake light which allows water to take a trip down the back of the taxi and soak the floorboards. This can reach the ORC module or the electrical wiring harnesses under the seats, triggering the air bag light to light up.
