In many Dodge Ram designs, a persistent warning light is accompanied by a chime or "ping" sound when the vehicle is started. This is developed to make sure the chauffeur does not neglect 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. Common codes for Dodge Ram airbag issues 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 factors can lead to the malfunction of an air bag sensor in a Dodge Ram 1500. Provided the truck's use in demanding environments, ecological aspects often play a large function.
- Rust: Because front impact sensors are located near the grille and frame, they are exposed to road salt, moisture, and debris. Gradually, the electrical connectors can corrode, breaking the circuit.
- Minor Collisions: Even a small "minor car accident" that does not deploy the airbags can damage the internal parts of a sensor, rendering it unresponsive.
- Water Damage: If the interior of the truck experiences a leak (common in older designs with dripping third brake lights or sunroof drains pipes), moisture can permeate into the B-pillar sensing units or the ORC module under the center console.
- Circuitry Issues: The wiring harnesses under the seats are susceptible to being pinched or disconnected when seats are moved often, typically affecting the Occupant Classification Sensor.
Historic Recalls and Safety Concerns
Owners of the Dodge Ram 1500 ought to understand historic recalls connected to the airbag system. Fiat Chrysler Automobiles (FCA) has actually released a number of remembers for many years to address software and hardware flaws.
- ORC Module Software (2013-2016 Models): A considerable recall was issued for these years because a software error could avoid 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 guiding wheel typically stops working in older Rams, breaking the connection to the driver-side airbag and triggering the SRS light.
- Sensor Housing Cracks: Some models faced concerns where the plastic housing of the effect sensors would split, permitting moisture to go into and short-circuit the system.
To examine if a particular Dodge Ram 1500 is impacted by a recall, owners must go to the Mopar or NHTSA site and enter their automobile's 17-digit VIN.
Medical diagnosis and Repair: What to Expect
Diagnosing an air bag concern is not a normal DIY job for the average enthusiast because it requires a customized scan tool efficient in reading SRS/ABS codes (basic cheap OBD-II scanners frequently just read engine codes).
The Diagnostic Process
- Scanning: A professional recovers the particular DTC to determine which sensor is failing.
- Visual Inspection: Checking the wiring harness and the sensor's physical condition for indications of corrosion or effect.
- Circuit Testing: Using a multimeter to check for continuity in the electrical wiring (Caution: This must be done with the battery detached to prevent unintentional deployment).
Replacement Steps
If a sensing unit is verified 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 allow the capacitors to discharge.
- Accessing the Sensor: Depending on the sensing unit, this might involve removing the front grille, interior trim panels, or the front seats.
- Part Swap: The old sensor is unbolted, and the brand-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 sensor is recognized by the ORC module.
