This guide offers an extensive take a look at the Dodge Ram 1500 airbag sensing unit system, covering its elements, common problems, and the necessary actions to guarantee 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 use a Supplemental Restraint System (SRS). This system is not meant to change seat belts but to operate in tandem with them. The air bag sensors act as the "anxious system" of the car. These parts are tactically put throughout the truck to identify abrupt deceleration or physical effect.
When an effect happens, the sensing units send out an electrical signal to the Occupant Restraint Control (ORC) module, which acts as the "brain" of the SRS. The ORC assesses the intensity of the impact and determines whether to deploy the airbags and pretension the seat belts. This whole process 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 different sensing units, each serving a particular function based on the instructions and type of effect.
| Sensor Type | Main Location | Function |
|---|---|---|
| Front Impact Sensors | Installed on the radiator support or front frame rails. | Finds head-on accidents 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 | Normally incorporated into the ORC module (center console area). | Spots the car's pitch and roll angle to release side drapes in a rollover. |
| Occupant Classifcation Sensor (OCS) | Inside the traveler seat cushion. | Figures out the weight of the traveler to adjust or disable airbag deployment for children. |
Common Symptoms of a Failing Airbag Sensor
When an air bag sensor stops working, the lorry's computer system typically detects the abnormality instantly. Since the SRS is important for safety, 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 turn on briefly when the ignition is started and after that vanish. If it stays lit or flashes while driving, the system has discovered a fault and has likely handicapped the air bag 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. Dodge Ram 1500 Airbags Shop is created to ensure the driver 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. Typical codes for Dodge Ram airbag 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
Numerous factors can cause the breakdown of an airbag sensing unit in a Dodge Ram 1500. Provided the truck's use in demanding environments, environmental factors often play a large function.
- Deterioration: Because front effect sensing units are located near the grille and frame, they are exposed to roadway salt, wetness, and debris. With time, the electrical connectors can corrode, breaking the circuit.
- Minor Collisions: Even a small "minor car accident" 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 designs with dripping third brake lights or sunroof drains pipes), wetness can seep into the B-pillar sensors or the ORC module under the center console.
- Electrical wiring Issues: The circuitry harnesses under the seats are susceptible to being pinched or detached when seats are moved frequently, frequently affecting the Occupant Classification Sensor.
Historic Recalls and Safety Concerns
Owners of the Dodge Ram 1500 must know historic recalls connected to the air bag system. Fiat Chrysler Automobiles (FCA) has released numerous recalls throughout the years to attend to software and hardware defects.
- ORC Module Software (2013-2016 Models): A considerable recall was released for these years since a software application mistake might prevent the side airbags and seatbelt pretensioners from releasing throughout a rollover.
- Clock Spring Failures: While not a sensing unit itself, the clock spring in the steering wheel typically stops working in older Rams, breaking the connection to the driver-side air bag and triggering the SRS light.
- Sensor Housing Cracks: Some models faced issues where the plastic real estate of the impact sensors would split, enabling wetness to go into and short-circuit the system.
To examine if a specific Dodge Ram 1500 is affected by a recall, owners ought to go to the Mopar or NHTSA website and enter their car's 17-digit VIN.
Diagnosis and Repair: What to Expect
Detecting an airbag problem is not a common DIY job for the average enthusiast due to the fact that it requires a specialized scan tool efficient in checking out SRS/ABS codes (basic inexpensive OBD-II scanners frequently just check out engine codes).
The Diagnostic Process
- Scanning: A professional recovers the particular DTC to identify which sensor is failing.
- Visual Inspection: Checking the wiring harness and the sensing unit's physical condition for indications of corrosion or effect.
- Circuit Testing: Using a multimeter to look for connection in the electrical wiring (Caution: This should be finished with the battery disconnected to prevent unexpected release).
Replacement Steps
If a sensor is confirmed faulty, replacement follows these general actions:
- Power Down: The battery must be disconnected, and the system must sit for at least 10-- 15 minutes to enable the capacitors to release.
- Accessing the Sensor: Depending on the sensing unit, this might involve eliminating the front grille, interior trim panels, or the front seats.
- Part Swap: The old sensor is unbolted, and the new OEM (Original Equipment Manufacturer) sensing unit is installed.
- System Reset: The professional clears the codes and carries out a "proxy positioning" or system calibration to make sure the brand-new sensing unit is acknowledged by the ORC module.
