Types of Airbag Sensors in the Dodge Ram 1500
The Ram 1500 is equipped with different sensing units, each serving a specific function based upon the direction and type of effect.
| Sensing unit Type | Main Location | Function |
|---|---|---|
| Front Impact Sensors | Mounted on the radiator support or front frame rails. | Spots head-on accidents and activates front airbags. |
| Side Impact Sensors | Located inside the doors or B-pillars. | Sets off side-curtain and seat-mounted airbags during T-bone accidents. |
| Rollover Sensors | Usually incorporated into the ORC module (center console location). | Identifies the lorry's pitch and roll angle to release side drapes in a rollover. |
| Resident Classifcation Sensor (OCS) | Inside the passenger seat cushion. | Identifies the weight of the traveler to change or disable air bag implementation for kids. |
Typical Symptoms of a Failing Airbag Sensor
When an airbag sensing unit fails, the automobile's computer system usually identifies the anomaly right away. Since the SRS is important for security, the lorry will notify the motorist through several signs.
1. The SRS Warning Light
The most common symptom is the illumination 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 vanish. If it stays lit or flashes while driving, the system has identified a fault and has likely disabled the airbag system.
2. Audible Chimes
In lots of Dodge Ram designs, a relentless caution light is accompanied by a chime or "ping" sound when the automobile is started. This is developed to make sure the chauffeur does not ignore 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, specific codes will appear. Typical codes for Dodge Ram airbag problems include:
- 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 lead to the malfunction of an airbag sensor in a Dodge Ram 1500. Provided the truck's usage in requiring environments, ecological aspects often play a large role.
- Deterioration: Because front effect sensing units are situated near the grille and frame, they are exposed to road salt, wetness, and debris. With 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 sensor, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leakage (typical in older models with leaking 3rd brake lights or sunroof drains), 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 prone to being pinched or detached when seats are moved regularly, typically impacting the Occupant Classification Sensor.
Historic Recalls and Safety Concerns
Owners of the Dodge Ram 1500 need to be mindful of historical recalls connected to the air bag system. Fiat Chrysler Automobiles (FCA) has provided numerous remembers over the years to deal with software application and hardware problems.
- ORC Module Software (2013-2016 Models): A substantial recall was issued for these years since a software error could avoid the side airbags and seatbelt pretensioners from releasing during a rollover.
- Clock Spring Failures: While not a sensing unit itself, the clock spring in the steering wheel typically fails 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 issues where the plastic housing of the impact sensing units would split, allowing wetness to go into and short-circuit the system.
To inspect if a specific Dodge Ram 1500 is impacted by a recall, owners should go to the Mopar or NHTSA website and enter their car's 17-digit VIN.
Medical diagnosis and Repair: What to Expect
Diagnosing an air bag concern is not a common DIY task for the typical lover since it needs a specialized scan tool capable of reading SRS/ABS codes (standard cheap OBD-II scanners frequently only read engine codes).
The Diagnostic Process
- Scanning: A professional obtains the particular DTC to determine which sensing unit is stopping working.
- Visual Inspection: Checking the wiring harness and the sensing unit's physical condition for indications of rust or effect.
- Circuit Testing: Using a multimeter to look for continuity in the electrical wiring (Caution: This should be finished with the battery detached to avoid unintentional implementation).
Replacement Steps
If a sensing unit is verified defective, 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 permit the capacitors to release.
- Accessing the Sensor: Depending on the sensor, this may include getting rid of the front grille, interior trim panels, or the front seats.
- Part Swap: The old sensor is unbolted, and the brand-new OEM (Original Equipment Manufacturer) sensor is installed.
- System Reset: The specialist clears the codes and performs a "proxy positioning" or system calibration to ensure the brand-new sensor is recognized by the ORC module.

Often Asked Questions (FAQ)
Can I drive my Dodge Ram with the air bag light on?
While the truck stays drivable, it is extremely discouraged. When the SRS light is illuminated, the system is in "fault mode," which normally means the airbags will not deploy in the event of a mishap. This significantly increases the risk of injury or death.
Where is the airbag sensing unit situated on a 2019+ Dodge Ram 1500?
The 5th-generation Ram (DT) has impact sensing units situated behind the front bumper cover on the frame rails and side impact sensing units situated 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 responsible for the SRS or ORC module blows, the system will lose power and set off the caution light. Checking the circuit box is typically the first and most inexpensive diagnostic step.
Do I need to use OEM parts for airbag sensing units?
It is strongly advised to utilize OEM Mopar sensors. The SRS is a life-saving system adjusted particularly to the lorry's crush zones and weight. Aftermarket sensors might not have the exact same precision or response times, possibly causing failure during a crash.
Can water leaks set off the airbag light in a Ram 1500?
Yes. A typical issue in Ram trucks is a leaking third brake light which permits water to take a trip down the back of the taxi and soak the floorboards. This can reach the ORC module or the circuitry harnesses under the seats, causing the airbag light to brighten.
