However, below the metal and leather lies a complex network of safety systems created to protect occupants in case of an accident. Central to this network is the air bag sensing unit system. Comprehending how these sensing units function, recognizing symptoms of failure, and knowing the steps for upkeep or replacement is vital for any Ram owner or service technician.
This guide provides a thorough look at the Dodge Ram 1500 air bag sensing unit system, covering its elements, typical problems, and the necessary actions to ensure the car remains a safe fortress for its travelers.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern cars like the Dodge Ram 1500 utilize a Supplemental Restraint System (SRS). This system is not intended to replace seatbelts but to work in tandem with them. The air bag sensing units act as the "nerve system" of the car. These parts are strategically positioned throughout the truck to spot unexpected deceleration or physical effect.
When an effect happens, the sensors send out an electrical signal to the Occupant Restraint Control (ORC) module, which functions as the "brain" of the SRS. The ORC evaluates the severity of the impact and determines whether to deploy the airbags and pretension the seat belts. This whole procedure takes place 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 sensing units, each serving a specific function based upon the instructions and kind of effect.
| Sensor Type | Primary Location | Function |
|---|---|---|
| Front Impact Sensors | Installed on the radiator support or front frame rails. | Finds head-on accidents and activates front airbags. |
| Side Impact Sensors | Found inside the doors or B-pillars. | Activates side-curtain and seat-mounted airbags throughout T-bone mishaps. |
| Rollover Sensors | Typically incorporated into the ORC module (center console area). | Discovers the automobile's pitch and roll angle to release side drapes in a rollover. |
| Occupant Classifcation Sensor (OCS) | Inside the guest seat cushion. | Figures out the weight of the passenger to adjust or disable air bag implementation for children. |
Common Symptoms of a Failing Airbag Sensor
When an airbag sensing unit fails, the car's computer system usually identifies the abnormality instantly. Because the SRS is important for security, the car will inform the driver through a number of indicators.
1. The SRS Warning Light
The most typical sign is the lighting of the "Airbag" or "SRS" light on the instrument cluster. Under typical conditions, this light ought to switch on briefly when the ignition is begun and after that disappear. If it remains lit or flashes while driving, the system has discovered a fault and has most likely disabled the air bag system.
2. Audible Chimes
In many Dodge Ram models, a consistent warning light is accompanied by a chime or "ping" sound when the vehicle is begun. This is developed to ensure the motorist 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 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
Several aspects can cause the breakdown of an airbag sensor in a Dodge Ram 1500. Offered Dodge Ram 1500 Airbags Customer Reviews in requiring environments, environmental elements typically play a large role.
- Deterioration: Because front impact sensing units lie near the grille and frame, they are exposed to road salt, moisture, and particles. With time, the electrical connectors can wear away, breaking the circuit.
- Minor Collisions: Even a small "minor car accident" that doesn't deploy the airbags can harm the internal components of a sensing unit, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leakage (typical in older models with dripping 3rd brake lights or sunroof drains pipes), wetness can permeate into the B-pillar sensors or the ORC module under the center console.
- Wiring Issues: The wiring harnesses under the seats are susceptible to being pinched or detached when seats are moved often, typically impacting the Occupant Classification Sensor.
Historic Recalls and Safety Concerns
Owners of the Dodge Ram 1500 should understand historical recalls associated with the airbag system. Fiat Chrysler Automobiles (FCA) has provided a number of recalls for many years to address software application and hardware problems.
- ORC Module Software (2013-2016 Models): A significant recall was provided for these years since a software application mistake might prevent the side airbags and seatbelt pretensioners from deploying during a rollover.
- Clock Spring Failures: While not a sensing unit itself, the clock spring in the guiding wheel frequently fails in older Rams, breaking the connection to the driver-side airbag and activating the SRS light.
- Sensor Housing Cracks: Some designs faced issues where the plastic real estate of the effect sensors would split, permitting wetness to enter and short-circuit the unit.
To check if a specific Dodge Ram 1500 is affected 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
Detecting an airbag concern is not a common DIY job for the average lover due to the fact that it needs a specific scan tool efficient in reading SRS/ABS codes (basic cheap OBD-II scanners typically just check out engine codes).
The Diagnostic Process
- Scanning: A specialist retrieves the specific DTC to recognize which sensing unit is stopping working.
- Visual Inspection: Checking the wiring harness and the sensing unit's physical condition for indications of corrosion or impact.
- Circuit Testing: Using a multimeter to look for connection in the wiring (Caution: This must be done with the battery detached to avoid unintentional deployment).
Replacement Steps
If a sensing unit is validated faulty, replacement follows these basic actions:
- Power Down: The battery needs to be detached, and the system must sit for at least 10-- 15 minutes to permit the capacitors to release.
- Accessing the Sensor: Depending on the sensing unit, this may include getting rid of 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 technician clears the codes and performs a "proxy positioning" or system calibration to make sure the new sensing unit is acknowledged by the ORC module.

Regularly Asked Questions (FAQ)
Can I drive my Dodge Ram with the air bag light on?
While the truck stays drivable, it is extremely prevented. When the SRS light is illuminated, the system is in "fault mode," which typically implies the airbags will not release in case of an accident. This significantly increases the danger of injury or death.
Where is the airbag sensing unit 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 effect sensors situated in the lower part of the B-pillars and C-pillars.
Will a blown fuse cause the airbag 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. Inspecting 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 strongly 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 sensors may not have the same precision or action times, potentially resulting in failure during a crash.
Can water leakages set off the air bag light in a Ram 1500?
Yes. A typical problem in Ram trucks is a leaking 3rd brake light which allows water to travel down the back of the cab and soak the floorboards. This can reach the ORC module or the circuitry harnesses under the seats, causing the air bag light to illuminate.
