This guide provides an extensive take a look at the Dodge Ram 1500 airbag sensing unit system, covering its elements, typical problems, and the needed steps to guarantee the car remains a safe fortress for its travelers.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern automobiles like the Dodge Ram 1500 make use of a Supplemental Restraint System (SRS). This system is not planned to replace seat belts but to work in tandem with them. The airbag sensors act as the "anxious system" of the car. These elements are strategically positioned throughout the truck to detect sudden deceleration or physical effect.
When an effect happens, the sensing units send out an electrical signal to the Occupant Restraint Control (ORC) module, which serves as the "brain" of the SRS. The ORC examines the intensity of the effect and identifies whether to deploy the airbags and pretension the seat belts. This whole procedure takes place within milliseconds-- faster than the blink of an eye.
Types of Airbag Sensors in the Dodge Ram 1500
The Ram 1500 is geared up with various sensing units, each serving a particular purpose based upon the direction and type of impact.
| Sensor Type | Primary Location | Function |
|---|---|---|
| Front Impact Sensors | Installed on the radiator assistance or front frame rails. | Finds head-on collisions and activates front airbags. |
| Side Impact Sensors | Found inside the doors or B-pillars. | Triggers side-curtain and seat-mounted airbags during T-bone accidents. |
| Rollover Sensors | Normally integrated into the ORC module (center console area). | Spots the car's pitch and roll angle to release side drapes in a rollover. |
| Resident Classifcation Sensor (OCS) | Inside the guest seat cushion. | Determines the weight of the passenger to change or disable airbag release for kids. |
Typical Symptoms of a Failing Airbag Sensor
When an air bag sensing unit fails, the automobile's computer system normally detects the anomaly right away. Because the SRS is important for safety, the automobile will alert the chauffeur through a number of signs.
1. The SRS Warning Light
The most typical symptom is the illumination of the "Airbag" or "SRS" light on the instrument cluster. Under learn more , this light must turn on briefly when the ignition is begun and then vanish. If it remains lit or flashes while driving, the system has spotted a fault and has likely handicapped the air bag system.
2. Audible Chimes
In many Dodge Ram designs, a consistent caution light is accompanied by a chime or "ping" noise when the lorry is started. This is created to guarantee the driver does not neglect 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 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
Numerous elements can lead to the breakdown of an airbag sensor in a Dodge Ram 1500. Offered the truck's use in requiring environments, environmental elements often play a big role.
- Deterioration: Because front effect sensing units are situated near the grille and frame, they are exposed to roadway salt, moisture, and particles. Gradually, the electrical connectors can wear away, breaking the circuit.
- Minor Collisions: Even a little "minor car accident" that does not release the airbags can damage the internal parts of a sensor, 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.
- Circuitry Issues: The circuitry utilizes under the seats are vulnerable 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 should know historical recalls associated with the air bag system. learn more (FCA) has actually provided several recalls over the years to deal with software application and hardware flaws.
- ORC Module Software (2013-2016 Models): A substantial recall was released for these years due to the fact that a software error could avoid 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 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 designs dealt with problems where the plastic real estate of the effect sensing units would break, permitting wetness to go into and short-circuit the unit.
To inspect if a specific Dodge Ram 1500 is impacted by a recall, owners ought to go to the Mopar or NHTSA website and enter their vehicle's 17-digit VIN.
Medical diagnosis and Repair: What to Expect
Identifying an airbag problem is not a common DIY job for the typical lover since it requires a customized scan tool efficient in checking out SRS/ABS codes (basic low-cost OBD-II scanners typically just read engine codes).
The Diagnostic Process
- Scanning: A technician retrieves the specific DTC to identify which sensor is stopping working.
- Visual Inspection: Checking the wiring harness and the sensing unit's physical condition for signs of corrosion or effect.
- Circuit Testing: Using a multimeter to check for connection in the circuitry (Caution: This need to be made with the battery detached to prevent unintentional deployment).
Replacement Steps
If a sensing unit is verified defective, replacement follows these basic steps:
- Power Down: The battery must be disconnected, and the system should 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 service technician clears the codes and carries out a "proxy positioning" or system calibration to ensure 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 stays drivable, it is extremely prevented. When the SRS light is illuminated, the system remains in "fault mode," which typically means the airbags will not deploy in case of an accident. This substantially increases the risk of injury or death.
Where is the air bag sensing unit located on a 2019+ Dodge Ram 1500?
The 5th-generation Ram (DT) has effect sensing units situated behind the front bumper cover on the frame rails and side effect sensors 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 caution light. Examining the fuse box is often the very first and most inexpensive diagnostic step.
Do I have to use OEM parts for airbag sensors?
It is strongly suggested to use OEM Mopar sensors. The SRS is a life-saving system calibrated specifically to the lorry's crush zones and weight. Aftermarket sensors might not have the very same precision or response times, possibly leading to failure during a crash.
Can water leakages set off the airbag light in a Ram 1500?
Yes. A common issue 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 circuitry utilizes under the seats, causing the airbag light to illuminate.
The air bag sensing unit system in the Dodge Ram 1500 is a sophisticated network designed with one objective: occupant safety. While these parts are constructed to be resilient, they are not unsusceptible to the impacts of time, environment, and mechanical failure.
