This guide supplies an in-depth appearance at the Dodge Ram 1500 air bag sensor system, covering its components, typical problems, and the necessary steps to guarantee the car 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 use a Supplemental Restraint System (SRS). This system is not meant to replace seat belts however to work in tandem with them. The airbag sensing units function as the "nervous system" of the vehicle. These parts are strategically positioned throughout the truck to spot abrupt deceleration or physical effect.
When an impact takes place, the sensing units send an electrical signal to the Occupant Restraint Control (ORC) module, which serves as the "brain" of the SRS. The ORC examines the severity of the impact and identifies whether to release the airbags and pretension the seatbelts. This entire procedure occurs within milliseconds-- faster than the blink of an eye.
Kinds Of Airbag Sensors in the Dodge Ram 1500
The Ram 1500 is equipped with different sensors, each serving a specific purpose based on the direction and kind of impact.
| Sensor Type | Main Location | Function |
|---|---|---|
| Front Impact Sensors | Installed on the radiator support or front frame rails. | Discovers head-on collisions and sets off front airbags. |
| Side Impact Sensors | Located inside the doors or B-pillars. | Activates side-curtain and seat-mounted airbags during T-bone accidents. |
| Rollover Sensors | Generally incorporated into the ORC module (center console location). | Spots the lorry's pitch and roll angle to release side drapes in a rollover. |
| Occupant Classifcation Sensor (OCS) | Inside the guest seat cushion. | Determines the weight of the traveler to adjust or disable air bag release for children. |
Common Symptoms of a Failing Airbag Sensor
When an airbag sensing unit stops working, the automobile's computer system normally spots the anomaly instantly. Due to the fact that the SRS is essential for safety, the car will notify the motorist through several signs.
1. The SRS Warning Light
The most common sign is the lighting of the "Airbag" or "SRS" light on the instrument cluster. Under regular conditions, this light should turn on briefly when the ignition is started and then vanish. If it stays lit or flashes while driving, the system has found a fault and has most likely disabled the airbag system.
2. Audible Chimes
In many Dodge Ram models, a relentless warning light is accompanied by a chime or "ping" sound when the vehicle is started. This is developed to make sure the driver does not overlook the visual warning 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 air bag issues 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
Several factors can result in the malfunction of an air bag sensing unit in a Dodge Ram 1500. Provided the truck's usage in demanding environments, ecological aspects typically play a large role.
- Deterioration: Because front effect sensors are situated near the grille and frame, they are exposed to road salt, wetness, and particles. In time, the electrical ports can corrode, breaking the circuit.
- Minor Collisions: Even a little "fender bender" that does not release the airbags can damage the internal elements of a sensing unit, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leakage (common in older designs with leaking third brake lights or sunroof drains pipes), moisture can leak into the B-pillar sensing units or the ORC module under the center console.
- Wiring Issues: The circuitry utilizes under the seats are susceptible to being pinched or disconnected when seats are moved regularly, frequently impacting the Occupant Classification Sensor.
Historical Recalls and Safety Concerns
Owners of the Dodge Ram 1500 should know historical recalls related to the air bag system. Fiat Chrysler Automobiles (FCA) has actually provided several remembers for many years to resolve software and hardware flaws.
- ORC Module Software (2013-2016 Models): A substantial recall was issued for these years because a software application error might prevent the side airbags and seatbelt pretensioners from releasing throughout a rollover.
- Clock Spring Failures: While not a sensor itself, the clock spring in the steering wheel often fails in older Rams, breaking the connection to the driver-side air bag and activating the SRS light.
- Sensor Housing Cracks: Some designs dealt with concerns where the plastic housing of the impact sensors would break, permitting moisture to get in and short-circuit the system.
To examine if a specific Dodge Ram 1500 is impacted by a recall, owners need to go to the Mopar or NHTSA website and enter their car's 17-digit VIN.
Diagnosis and Repair: What to Expect
Detecting an air bag concern is not a normal DIY job for the average lover because it needs a specialized scan tool capable of checking out SRS/ABS codes (standard low-cost OBD-II scanners often just read engine codes).
The Diagnostic Process
- Scanning: A professional recovers the particular DTC to determine which sensor is stopping working.
- Visual Inspection: Checking the circuitry 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 finished with the battery detached to prevent unexpected deployment).
Replacement Steps
If a sensor is verified defective, replacement follows these general steps:
- Power Down: The battery must be disconnected, and the system should sit for at least 10-- 15 minutes to permit the capacitors to discharge.
- Accessing the Sensor: Depending on the sensing unit, this may involve getting rid of the front grille, interior trim panels, or the front seats.
- Component Swap: The old sensor is unbolted, and the 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 brand-new sensing unit is recognized by the ORC module.
