This guide offers a thorough appearance at the Dodge Ram 1500 air bag sensor system, covering its components, typical issues, and the necessary actions to guarantee the car stays 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 meant to change seatbelts but to operate in tandem with them. The airbag sensing units function as the "nerve system" of the vehicle. These elements are tactically positioned throughout the truck to spot sudden deceleration or physical effect.
When an impact takes place, the sensing units send an electrical signal to the Occupant Restraint Control (ORC) module, which works as the "brain" of the SRS. The ORC assesses the intensity of the impact and determines whether to release the airbags and pretension the seatbelts. This entire process 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 various sensing units, each serving a particular function based on the instructions and kind of effect.
| Sensing unit Type | Primary Location | Function |
|---|---|---|
| Front Impact Sensors | Mounted on the radiator assistance or front frame rails. | Detects head-on collisions and triggers 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 | Typically integrated into the ORC module (center console area). | Identifies the car's pitch and roll angle to deploy 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 airbag release for kids. |
Typical Symptoms of a Failing Airbag Sensor
When an airbag sensing unit stops working, the car's computer system normally detects the abnormality immediately. Since the SRS is important for safety, the automobile will alert the chauffeur through a number of indicators.
1. The SRS Warning Light
The most common sign is the lighting of the "Airbag" or "SRS" light on the instrument cluster. Under learn more , this light needs to switch on briefly when the ignition is started and after that disappear. If it stays lit or flashes while driving, the system has identified a fault and has most likely handicapped the air bag system.
2. Audible Chimes
In lots of Dodge Ram designs, a persistent caution light is accompanied by a chime or "ping" sound when the car is begun. This is developed to ensure the driver 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, particular codes will appear. Common 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.
Reasons For Airbag Sensor Failure
A number of aspects can cause the malfunction of an air bag sensor in a Dodge Ram 1500. Provided the truck's usage in demanding environments, environmental elements typically play a large function.
- Corrosion: Because front impact sensors are located near the grille and frame, they are exposed to roadway salt, moisture, and debris. Over time, the electrical ports can rust, breaking the circuit.
- Minor Collisions: Even a little "minor car accident" that doesn't release the airbags can harm the internal elements of a sensor, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leak (typical in older models with leaking 3rd brake lights or sunroof drains pipes), wetness can seep into the B-pillar sensors or the ORC module under the center console.
- Electrical wiring Issues: The circuitry harnesses under the seats are susceptible to being pinched or detached when seats are moved frequently, frequently affecting the Occupant Classification Sensor.
Historical Recalls and Safety Concerns
Owners of the Dodge Ram 1500 ought to know historical recalls associated with the airbag system. Fiat Chrysler Automobiles (FCA) has provided several remembers throughout the years to address software and hardware flaws.
- ORC Module Software (2013-2016 Models): A considerable recall was provided for these years due to the fact that a software 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 guiding wheel typically fails in older Rams, breaking the connection to the driver-side air bag and setting off the SRS light.
- Sensor Housing Cracks: Some designs dealt with concerns where the plastic real estate of the effect sensing units would crack, permitting wetness to get in and short-circuit the unit.
To inspect if a specific Dodge Ram 1500 is impacted by a recall, owners need to go to the Mopar or NHTSA site and enter their automobile's 17-digit VIN.
Diagnosis and Repair: What to Expect
Detecting an air bag issue is not a normal DIY job for the average lover because it needs a specific scan tool efficient in reading SRS/ABS codes (standard low-cost OBD-II scanners frequently only check out engine codes).
The Diagnostic Process
- Scanning: A professional retrieves 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 impact.
- Circuit Testing: Using a multimeter to look for connection in the electrical wiring (Caution: This should be made with the battery disconnected to avoid unexpected deployment).
Replacement Steps
If a sensor is validated faulty, replacement follows these general steps:
- Power Down: The battery should be detached, and the system needs to sit for a minimum of 10-- 15 minutes to enable the capacitors to release.
- Accessing the Sensor: Depending on the sensor, this may involve removing the front grille, interior trim panels, or the front seats.
- Element Swap: The old sensor is unbolted, and the brand-new OEM (Original Equipment Manufacturer) sensor is set up.
- System Reset: The specialist clears the codes and performs a "proxy positioning" or system calibration to make sure the brand-new sensor is recognized by the ORC module.

Regularly Asked Questions (FAQ)
Can I drive my Dodge Ram with the air bag light on?
While the truck remains drivable, it is highly discouraged. When the SRS light is brightened, the system remains in "fault mode," which typically means the airbags will not release in the occasion of an accident. This considerably increases the threat of injury or death.
Where is the airbag sensing unit located 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 portion of the B-pillars and C-pillars.
Will a blown fuse trigger the air bag light to come on?
Yes. If the fuse accountable for the SRS or ORC module blows, the system will lose power and activate the warning light. Inspecting the fuse box is often the first and most affordable diagnostic step.
Do I have to utilize OEM parts for air bag sensing units?
It is highly advised to utilize OEM Mopar sensors. The SRS is a life-saving system adjusted particularly to the automobile's crush zones and weight. Aftermarket sensors may not have the exact same precision or action times, potentially resulting in failure during a crash.
Can water leakages trigger the air bag light in a Ram 1500?
Yes. A typical concern in Ram trucks is a dripping third brake light which enables water to travel down the back of the cab and soak the floorboards. This can reach the ORC module or the wiring harnesses under the seats, causing the airbag light to brighten.
