This guide supplies a thorough look at the Dodge Ram 1500 airbag sensor system, covering its parts, common concerns, and the necessary steps to ensure the vehicle remains a safe fortress for its passengers.
The Role of Airbag Sensors in the Supplemental Restraint System (SRS)
Modern automobiles like the Dodge Ram 1500 utilize a Supplemental Restraint System (SRS). This system is not intended to change seat belts however to operate in tandem with them. The airbag sensors act as the "nerve system" of the vehicle. These parts are tactically placed throughout the truck to spot abrupt deceleration or physical impact.
When an impact takes place, the sensors send an electrical signal to the Occupant Restraint Control (ORC) module, which acts as the "brain" of the SRS. The ORC evaluates the severity of the impact and figures out 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 sensors, each serving a particular function based upon the instructions and kind of impact.
| Sensing unit Type | Primary Location | Function |
|---|---|---|
| Front Impact Sensors | Mounted on the radiator support or front frame rails. | Spots head-on collisions and triggers front airbags. |
| Side Impact Sensors | Located inside the doors or B-pillars. | Triggers side-curtain and seat-mounted airbags throughout T-bone mishaps. |
| Rollover Sensors | Typically integrated into the ORC module (center console area). | Finds the car's pitch and roll angle to release side curtains in a rollover. |
| Occupant Classifcation Sensor (OCS) | Inside the passenger seat cushion. | Determines the weight of the guest to adjust or disable air bag release for children. |
Typical Symptoms of a Failing Airbag Sensor
When an airbag sensor stops working, the automobile's computer system normally spots the abnormality instantly. Since the SRS is essential for security, the vehicle will alert the driver through a number of indications.
1. The SRS Warning Light
The most typical symptom is the lighting of the "Airbag" or "SRS" light on the instrument cluster. Under regular conditions, this light ought to turn on briefly when the ignition is started and after that vanish. If it stays lit or flashes while driving, the system has actually discovered a fault and has likely handicapped 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 vehicle is begun. This is developed to make sure the motorist does not ignore the visual warning 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. Common codes for Dodge Ram air bag 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.
Reasons For Airbag Sensor Failure
Several elements can lead to the malfunction of an air bag sensor in a Dodge Ram 1500. Given the truck's use in requiring environments, environmental aspects often play a large function.
- Corrosion: Because front effect sensing units lie near the grille and frame, they are exposed to road salt, moisture, and particles. Gradually, the electrical ports can rust, breaking the circuit.
- Minor Collisions: Even a little "minor car accident" that does not deploy 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 (typical in older models with leaking third brake lights or sunroof drains pipes), moisture can seep into the B-pillar sensors or the ORC module under the center console.
- Circuitry Issues: The circuitry utilizes under the seats are vulnerable to being pinched or disconnected when seats are moved regularly, frequently affecting the Occupant Classification Sensor.
Historic Recalls and Safety Concerns
Owners of the Dodge Ram 1500 should be aware of historical recalls connected to the airbag system. Fiat Chrysler Automobiles (FCA) has actually provided several remembers over the years to address software application and hardware defects.
- ORC Module Software (2013-2016 Models): A substantial recall was issued for these years since a software application mistake might avoid the side airbags and seat belt pretensioners from releasing during a rollover.
- Clock Spring Failures: While not a sensing unit itself, the clock spring in the steering wheel often stops working in older Rams, breaking the connection to the driver-side airbag and setting off the SRS light.
- Sensing Unit Housing Cracks: Some designs dealt with issues where the plastic housing of the impact sensing units would break, allowing wetness to enter and short-circuit the system.
To examine if a particular Dodge Ram 1500 is impacted by a recall, owners need 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 issue is not a typical DIY job for the average enthusiast because it needs a specific scan tool capable of checking out SRS/ABS codes (standard low-cost OBD-II scanners often just check out engine codes).
The Diagnostic Process
- Scanning: A technician recovers the particular DTC to identify which sensing unit is failing.
- Visual Inspection: Checking the circuitry harness and the sensor's physical condition for indications of corrosion or effect.
- Circuit Testing: Using a multimeter to inspect for continuity in the electrical wiring (Caution: This must be finished with the battery detached to avoid unintentional deployment).
Replacement Steps
If a sensor is validated faulty, 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 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 sensing unit is unbolted, and the 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 sensing unit is recognized by the ORC module.
