This guide provides a thorough look at the Dodge Ram 1500 airbag sensing unit system, covering its parts, typical problems, and the required actions to guarantee the car remains a safe fortress for its travelers.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern cars like the Dodge Ram 1500 utilize a Supplemental Restraint System (SRS). This system is not intended to change seatbelts however to work in tandem with them. The air bag sensors serve as the "nerve system" of the car. These elements are strategically placed throughout the truck to find 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. Dodge Ram 1500 Airbags Aftermarket Parts of the effect and figures out whether to deploy the airbags and pretension the seatbelts. This entire procedure occurs within milliseconds-- faster than the blink of an eye.
Types of Airbag Sensors in the Dodge Ram 1500
The Ram 1500 is equipped with numerous sensing units, each serving a specific function based on the instructions and kind of effect.
| Sensor Type | Primary Location | Function |
|---|---|---|
| Front Impact Sensors | Mounted on the radiator assistance or front frame rails. | Discovers head-on accidents and sets off front airbags. |
| Side Impact Sensors | Located inside the doors or B-pillars. | Triggers side-curtain and seat-mounted airbags during T-bone mishaps. |
| Rollover Sensors | Generally integrated into the ORC module (center console area). | Detects the automobile's pitch and roll angle to deploy side drapes in a rollover. |
| Occupant Classifcation Sensor (OCS) | Inside the traveler seat cushion. | Figures out the weight of the passenger to adjust or disable air bag implementation for children. |
Typical Symptoms of a Failing Airbag Sensor
When an airbag sensor fails, the automobile's computer system normally discovers the abnormality right away. Due to the fact that the SRS is essential for safety, the lorry will alert the chauffeur through several indicators.
1. The SRS Warning Light
The most typical sign is the illumination of the "Airbag" or "SRS" light on the instrument cluster. Under regular conditions, this light needs to turn on briefly when the ignition is started and after that disappear. If it remains lit or flashes while driving, the system has actually spotted a fault and has likely disabled the airbag system.
2. Audible Chimes
In many Dodge Ram designs, a relentless caution light is accompanied by a chime or "ping" sound when the lorry is started. This is created to ensure the chauffeur does not neglect 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.
Causes of Airbag Sensor Failure
A number of aspects can lead to the breakdown of an airbag sensor in a Dodge Ram 1500. Given the truck's usage in requiring environments, ecological aspects typically play a big function.
- Rust: Because front effect sensing units are located near the grille and frame, they are exposed to road salt, wetness, and debris. Over time, the electrical adapters can rust, breaking the circuit.
- Minor Collisions: Even a small "fender bender" that doesn't release 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 (typical in older designs with dripping third brake lights or sunroof drains), moisture can seep into the B-pillar sensors or the ORC module under the center console.
- Electrical wiring Issues: The wiring harnesses under the seats are susceptible to being pinched or disconnected when seats are moved frequently, frequently affecting the Occupant Classification Sensor.
Historical Recalls and Safety Concerns
Owners of the Dodge Ram 1500 should be conscious of historic recalls related to the air bag system. Fiat Chrysler Automobiles (FCA) has released a number of remembers for many years to attend to software and hardware problems.
- ORC Module Software (2013-2016 Models): A significant recall was released for these years because a software application mistake might prevent the side airbags and seat belt pretensioners from deploying throughout a rollover.
- Clock Spring Failures: While not a sensor itself, the clock spring in the steering wheel often stops working in older Rams, breaking the connection to the driver-side air bag and activating the SRS light.
- Sensing Unit Housing Cracks: Some models dealt with problems where the plastic real estate of the effect sensing units would break, permitting moisture to go into and short-circuit the unit.
To examine if a particular Dodge Ram 1500 is impacted by a recall, owners need to go to the Mopar or NHTSA website and enter their vehicle's 17-digit VIN.
Medical diagnosis and Repair: What to Expect
Detecting an airbag issue is not a normal DIY task for the average enthusiast due to the fact that it requires a specific scan tool efficient in checking out SRS/ABS codes (basic cheap OBD-II scanners frequently just check out engine codes).
The Diagnostic Process
- Scanning: A service technician recovers the specific DTC to recognize which sensing unit is stopping working.
- Visual Inspection: Checking the wiring harness and the sensor's physical condition for signs of rust or effect.
- Circuit Testing: Using a multimeter to look for connection in the circuitry (Caution: This must be finished with the battery disconnected to avoid unexpected implementation).
Replacement Steps
If a sensor is confirmed faulty, replacement follows these general steps:
- Power Down: The battery should 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 involve removing 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 installed.
- System Reset: The specialist clears the codes and performs a "proxy alignment" or system calibration to make sure the brand-new sensing unit 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 dissuaded. When the SRS light is illuminated, the system remains in "fault mode," which normally means the airbags will not deploy in the occasion of an accident. This substantially increases the threat of injury or death.
Where is the airbag 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 effect sensing units situated in the lower part of the B-pillars and C-pillars.
Will a blown fuse cause 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. Inspecting the circuit box is typically the first and cheapest diagnostic step.
Do I have to use OEM parts for airbag sensors?
It is strongly advised to utilize OEM Mopar sensing units. The SRS is a life-saving system adjusted particularly to the car's crush zones and weight. Aftermarket sensors may not have the very same accuracy or response times, possibly resulting in failure throughout a crash.
Can water leakages trigger the airbag light in a Ram 1500?
Yes. A typical concern in Ram trucks is a leaking 3rd brake light which allows water to travel down the back of the taxi and soak the floorboards. This can reach the ORC module or the wiring harnesses under the seats, triggering the air bag light to light up.
