Comprehending how these sensors function, acknowledging signs of failure, and knowing the actions for upkeep or replacement is crucial for any Ram owner or service technician.
This guide provides an extensive take a look at the Dodge Ram 1500 airbag sensor system, covering its parts, common concerns, and the essential actions to make sure the lorry remains a safe fortress for its passengers.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern lorries like the Dodge Ram 1500 utilize a Supplemental Restraint System (SRS). This system is not intended to replace seat belts however to operate in tandem with them. The air bag sensors serve as the "nerve system" of the automobile. These parts are tactically placed throughout the truck to find unexpected deceleration or physical effect.
When an effect occurs, the sensors send out an electrical signal to the Occupant Restraint Control (ORC) module, which serves as the "brain" of the SRS. The ORC assesses the severity of the impact and identifies whether to deploy the airbags and pretension the seat belts. This whole procedure happens within milliseconds-- faster than the blink of an eye.
Kinds Of Airbag Sensors in the Dodge Ram 1500
The Ram 1500 is equipped with various sensors, each serving a particular function based upon the instructions and kind of impact.
| Sensor Type | Main Location | Function |
|---|---|---|
| Front Impact Sensors | Installed on the radiator support or front frame rails. | Spots head-on collisions 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). | Discovers the lorry's pitch and roll angle to deploy side drapes in a rollover. |
| Resident Classifcation Sensor (OCS) | Inside the traveler seat cushion. | Determines the weight of the traveler to change or disable airbag implementation for children. |
Typical Symptoms of a Failing Airbag Sensor
When an air bag sensor fails, the lorry's computer system generally identifies the anomaly immediately. Due to the fact that the SRS is important for security, the lorry will alert the chauffeur through several indications.
1. The SRS Warning Light
The most typical symptom is the illumination of the "Airbag" or "SRS" light on the instrument cluster. Under regular conditions, this light needs to switch on briefly when the ignition is started and then disappear. If it stays lit or flashes while driving, the system has actually identified a fault and has likely disabled the airbag system.
2. Audible Chimes
In lots of Dodge Ram designs, a relentless warning light is accompanied by a chime or "ping" noise when the car is begun. This is designed to guarantee the motorist 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, particular codes will appear. Common codes for Dodge Ram airbag concerns 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 elements can cause the breakdown of an airbag sensor in a Dodge Ram 1500. Offered website in demanding environments, environmental factors frequently play a large role.
- Deterioration: Because front effect sensors lie near the grille and frame, they are exposed to road salt, wetness, and particles. Over time, the electrical connectors can corrode, breaking the circuit.
- Minor Collisions: Even a small "minor car accident" that does not release the airbags can damage the internal components of a sensor, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leak (typical in older designs with leaking 3rd brake lights or sunroof drains pipes), wetness can leak into the B-pillar sensors or the ORC module under the center console.
- Wiring Issues: The electrical wiring harnesses under the seats are prone to being pinched or detached when seats are moved often, often impacting the Occupant Classification Sensor.
Historical Recalls and Safety Concerns
Owners of the Dodge Ram 1500 ought to know historic recalls associated with the airbag system. Fiat Chrysler Automobiles (FCA) has actually released a number of remembers over the years to attend to software application and hardware problems.
- ORC Module Software (2013-2016 Models): A significant recall was issued for these years because a software application mistake could avoid the side airbags and seat belt pretensioners from deploying during 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 concerns where the plastic real estate of the impact sensors would split, allowing moisture to go into and short-circuit the unit.
To inspect if a specific Dodge Ram 1500 is affected by a recall, owners ought to go to the Mopar or NHTSA site and enter their automobile's 17-digit VIN.
Medical diagnosis and Repair: What to Expect
Identifying an airbag problem is not a typical DIY task for the average lover because it requires a customized scan tool capable of checking out SRS/ABS codes (standard cheap OBD-II scanners typically only read engine codes).
The Diagnostic Process
- Scanning: A service technician recovers the particular DTC to recognize which sensor is stopping working.
- Visual Inspection: Checking the circuitry harness and the sensor's physical condition for indications of deterioration or effect.
- Circuit Testing: Using a multimeter to look for connection in the circuitry (Caution: This need to be made with the battery detached to prevent unexpected deployment).
Replacement Steps
If a sensing unit is validated faulty, replacement follows these basic steps:
- Power Down: The battery must be disconnected, and the system must sit for a minimum of 10-- 15 minutes to allow the capacitors to release.
- Accessing the Sensor: Depending on the sensor, this might include removing the front grille, interior trim panels, or the front seats.
- Component Swap: The old sensing unit is unbolted, and the new OEM (Original Equipment Manufacturer) sensing unit is set up.
- System Reset: The technician clears the codes and carries out 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 airbag light on?
While the truck stays drivable, it is highly discouraged. When the SRS light is brightened, the system is in "fault mode," which usually means the airbags will not release in case of an accident. This significantly increases the risk of injury or death.
Where is the air bag sensor located 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 sensors situated in the lower part of the B-pillars and C-pillars.
Will a blown fuse cause 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 trigger the caution light. Checking the fuse box is typically the first and most inexpensive diagnostic action.
Do I need to utilize OEM parts for airbag sensing units?
It is highly recommended to use OEM Mopar sensing units. The SRS is a life-saving system calibrated particularly to the vehicle's crush zones and weight. click here might not have the exact same accuracy or reaction times, possibly causing failure throughout a crash.
Can water leaks set off the airbag light in a Ram 1500?
Yes. A common issue in Ram trucks is a leaking third brake light which allows water to take a trip down the back of the taxi and soak the floorboards. This can reach the ORC module or the electrical wiring utilizes under the seats, triggering the airbag light to brighten.
