This guide provides an in-depth take a look at the Dodge Ram 1500 airbag sensing unit system, covering its components, typical problems, and the required steps to ensure the car remains a safe fortress for its passengers.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern lorries like the Dodge Ram 1500 utilize a Supplemental Restraint System (SRS). This system is not meant to change seat belts however to operate in tandem with them. The airbag sensing units serve as the "nerve system" of the vehicle. These elements are tactically put throughout the truck to spot unexpected deceleration or physical impact.
When an effect happens, the sensors send out an electrical signal to the Occupant Restraint Control (ORC) module, which works as the "brain" of the SRS. The ORC examines the severity of the impact and figures out whether to release the airbags and pretension the seat belts. 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 equipped with numerous sensing units, each serving a particular purpose based upon the instructions and type of effect.
| Sensing unit Type | Primary Location | Function |
|---|---|---|
| Front Impact Sensors | Mounted on the radiator assistance or front frame rails. | Detects head-on crashes and triggers front airbags. |
| Side Impact Sensors | Found inside the doors or B-pillars. | Activates side-curtain and seat-mounted airbags during T-bone mishaps. |
| Rollover Sensors | Typically integrated into the ORC module (center console area). | Finds the lorry's pitch and roll angle to release side curtains in a rollover. |
| Resident Classifcation Sensor (OCS) | Inside the passenger seat cushion. | Figures out the weight of the traveler to adjust or disable air bag release for kids. |
Typical Symptoms of a Failing Airbag Sensor
When an air bag sensing unit fails, the car's computer system usually discovers the abnormality instantly. Because the SRS is essential for safety, the automobile will signal the motorist through several indicators.
1. The SRS Warning Light
The most common sign is the illumination of the "Airbag" or "SRS" light on the instrument cluster. Under regular conditions, this light must turn on briefly when the ignition is started and after that vanish. If it stays lit or flashes while driving, the system has spotted a fault and has most likely disabled the airbag system.
2. Audible Chimes
In many Dodge Ram models, a persistent caution light is accompanied by a chime or "ping" sound when the car is started. This is created to ensure the motorist does not overlook the visual caution 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 air bag problems 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.
Reasons For Airbag Sensor Failure
A number of elements can lead to the malfunction of an airbag sensor in a Dodge Ram 1500. Given Dodge Ram 1500 Airbags Customer Reviews in requiring environments, environmental elements frequently play a big role.
- Deterioration: Because front impact sensors lie near the grille and frame, they are exposed to road salt, wetness, and debris. Over time, the electrical ports can rust, breaking the circuit.
- Minor Collisions: Even a little "fender bender" that doesn't deploy the airbags can harm the internal components of a sensing unit, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leak (common in older designs with leaking 3rd brake lights or sunroof drains), moisture can leak into the B-pillar sensing units 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 frequently, typically impacting the Occupant Classification Sensor.
Historic Recalls and Safety Concerns
Owners of the Dodge Ram 1500 ought to be conscious of historical recalls associated with the airbag system. Fiat Chrysler Automobiles (FCA) has issued several recalls throughout the years to resolve software application and hardware problems.
- ORC Module Software (2013-2016 Models): A considerable recall was issued for these years since a software application error might prevent 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 typically stops working in older Rams, breaking the connection to the driver-side airbag and activating the SRS light.
- Sensor Housing Cracks: Some models faced concerns where the plastic housing of the impact sensors would break, allowing moisture to get in and short-circuit the system.
To examine if a particular Dodge Ram 1500 is affected by a recall, owners ought to check out the Mopar or NHTSA website and enter their lorry's 17-digit VIN.
Medical diagnosis and Repair: What to Expect
Detecting an airbag concern is not a typical DIY task for the average enthusiast since it requires a specialized scan tool capable of checking out SRS/ABS codes (standard low-cost OBD-II scanners frequently only read engine codes).
The Diagnostic Process
- Scanning: A technician recovers the specific DTC to recognize which sensor is failing.
- Visual Inspection: Checking the circuitry harness and the sensor's physical condition for indications of rust or impact.
- Circuit Testing: Using a multimeter to inspect for continuity in the circuitry (Caution: This must be finished with the battery disconnected to prevent unintentional release).
Replacement Steps
If a sensor is verified faulty, replacement follows these general actions:
- Power Down: The battery needs to be detached, and the system should sit for a minimum of 10-- 15 minutes to allow the capacitors to discharge.
- Accessing the Sensor: Depending on the sensor, this might involve removing the front grille, interior trim panels, or the front seats.
- Part Swap: The old sensor is unbolted, and the new OEM (Original Equipment Manufacturer) sensor is set up.
- System Reset: The professional clears the codes and carries out a "proxy alignment" or system calibration to guarantee the new sensor is acknowledged by the ORC module.

Often Asked Questions (FAQ)
Can I drive my Dodge Ram with the airbag light on?
While the truck stays drivable, it is extremely prevented. When the SRS light is brightened, the system is in "fault mode," which usually indicates the airbags will not deploy in the event of a mishap. This substantially increases the risk 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 located behind the front bumper cover on the frame rails and side impact sensors situated in the lower portion of the B-pillars and C-pillars.
Will a blown fuse cause the airbag light to come on?
Yes. If the fuse responsible for the SRS or ORC module blows, the system will lose power and activate the warning light. Checking the fuse box is often the very first and most affordable diagnostic step.
Do I need to use OEM parts for air bag sensing units?
It is highly suggested to use OEM Mopar sensors. The SRS is a life-saving system calibrated specifically to the car's crush zones and weight. Aftermarket sensing units might not have the very same precision or action times, possibly causing failure throughout a crash.
Can water leaks set off the air bag light in a Ram 1500?
Yes. A common issue in Ram trucks is a leaking third brake light which permits water to travel down the back of the cab and soak the floorboards. This can reach the ORC module or the circuitry harnesses under the seats, causing the air bag light to illuminate.
