This guide supplies a thorough look at the Dodge Ram 1500 air bag sensing unit system, covering its components, common issues, and the essential actions to make sure the lorry stays a safe fortress for its guests.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern automobiles like the Dodge Ram 1500 utilize a Supplemental Restraint System (SRS). Dodge Ram 1500 Airbags New is not planned to replace seatbelts however to work in tandem with them. The airbag sensing units serve as the "nerve system" of the car. These elements are strategically placed throughout the truck to spot abrupt deceleration or physical effect.
When an effect happens, the sensors send an electrical signal to the Occupant Restraint Control (ORC) module, which acts as the "brain" of the SRS. The ORC assesses the seriousness of the impact and determines whether to release the airbags and pretension the seat belts. This whole process occurs 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 different sensing units, each serving a particular function based on the instructions and type of impact.
| Sensing unit Type | Main Location | Function |
|---|---|---|
| Front Impact Sensors | Installed on the radiator support or front frame rails. | Finds head-on crashes and triggers front airbags. |
| Side Impact Sensors | Located inside the doors or B-pillars. | Activates side-curtain and seat-mounted airbags throughout T-bone mishaps. |
| Rollover Sensors | Normally incorporated into the ORC module (center console area). | Spots the lorry's pitch and roll angle to deploy side curtains in a rollover. |
| Occupant Classifcation Sensor (OCS) | Inside the traveler seat cushion. | Determines the weight of the traveler to adjust or disable air bag implementation for children. |
Common Symptoms of a Failing Airbag Sensor
When an air bag sensor fails, the automobile's computer system generally spots the anomaly immediately. Because the SRS is vital for security, the car will inform the chauffeur through numerous signs.
1. The SRS Warning Light
The most common symptom is the illumination of the "Airbag" or "SRS" light on the instrument cluster. Under regular conditions, this light must switch on briefly when the ignition is begun and after that disappear. If it stays lit or flashes while driving, the system has actually spotted a fault and has likely handicapped the airbag system.
2. Audible Chimes
In numerous Dodge Ram models, a persistent caution light is accompanied by a chime or "ping" noise when the vehicle is begun. This is created to guarantee the driver 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 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 factors can result in the breakdown of an airbag sensing unit in a Dodge Ram 1500. Given the truck's usage in requiring environments, environmental elements typically play a large function.
- Deterioration: Because front impact sensing units are located near the grille and frame, they are exposed to road salt, wetness, and particles. Over time, the electrical connectors can rust, breaking the circuit.
- Minor Collisions: Even a small "fender bender" that doesn't deploy the airbags can harm the internal elements of a sensing unit, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leakage (typical in older models with leaking third brake lights or sunroof drains pipes), moisture can permeate into the B-pillar sensors or the ORC module under the center console.
- Wiring Issues: The electrical wiring utilizes under the seats are vulnerable to being pinched or disconnected when seats are moved regularly, typically affecting the Occupant Classification Sensor.
Historical Recalls and Safety Concerns
Owners of the Dodge Ram 1500 should understand historical recalls associated with the airbag system. Fiat Chrysler Automobiles (FCA) has actually released several remembers over the years to address software application and hardware problems.
- ORC Module Software (2013-2016 Models): A considerable recall was issued for these years because a software mistake could avoid the side airbags and seatbelt pretensioners from deploying throughout a rollover.
- Clock Spring Failures: While not a sensing unit itself, the clock spring in the guiding wheel typically stops working in older Rams, breaking the connection to the driver-side air bag and setting off the SRS light.
- Sensing Unit Housing Cracks: Some models dealt with issues where the plastic real estate of the impact sensing units would break, allowing moisture to get in and short-circuit the unit.
To examine if a particular Dodge Ram 1500 is impacted by a recall, owners ought to check out the Mopar or NHTSA site and enter their vehicle's 17-digit VIN.
Medical diagnosis and Repair: What to Expect
Identifying an air bag problem is not a typical DIY task for the typical enthusiast since it requires a customized scan tool capable of checking out SRS/ABS codes (basic cheap OBD-II scanners typically only check out engine codes).
The Diagnostic Process
- Scanning: A service technician retrieves the specific DTC to recognize 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 inspect for continuity in the electrical wiring (Caution: This must be done with the battery disconnected to avoid unintentional implementation).
Replacement Steps
If a sensing unit is verified faulty, replacement follows these basic actions:
- Power Down: The battery should be detached, and the system should sit for a minimum of 10-- 15 minutes to enable the capacitors to release.
- Accessing the Sensor: Depending on the sensor, this may include removing the front grille, interior trim panels, or the front seats.
- Part Swap: The old sensing unit is unbolted, and the brand-new OEM (Original Equipment Manufacturer) sensing unit is set up.
- System Reset: The specialist clears the codes and carries out a "proxy alignment" or system calibration to make sure the new sensor is acknowledged by the ORC module.

Frequently Asked Questions (FAQ)
Can I drive my Dodge Ram with the air bag light on?
While the truck remains drivable, it is extremely discouraged. When the SRS light is brightened, the system remains in "fault mode," which typically suggests the airbags will not deploy in case of a mishap. This significantly increases the danger of injury or death.
Where is the airbag sensor located on a 2019+ Dodge Ram 1500?
The 5th-generation Ram (DT) has impact sensing units located behind the front bumper cover on the frame rails and side impact sensors situated in the lower part of the B-pillars and C-pillars.
Will a blown fuse trigger the air bag light to come on?
Yes. If the fuse responsible for the SRS or ORC module blows, the system will lose power and trigger the warning light. Checking the circuit box is often the very first and most affordable diagnostic action.
Do I need to use OEM parts for airbag sensors?
It is highly advised to utilize OEM Mopar sensing units. The SRS is a life-saving system calibrated particularly to the lorry's crush zones and weight. Aftermarket sensing units may not have the same accuracy or action times, potentially resulting in failure throughout a crash.
Can water leaks trigger the airbag light in a Ram 1500?
Yes. A common problem in Ram trucks is a dripping 3rd 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 electrical wiring harnesses under the seats, causing the airbag light to brighten.
