What is a Chrysler Concorde LH airbag control unit?
The Chrysler Concorde LH airbag control unit is the central safety unit that activates all occupant restraint systems on the left driver's side in the event of a collision. It precisely monitors sensors, stores relevant crash data, and ensures proper function and deployment of the airbag modules to provide maximum safety.
As an integral part of the Occupant Restraint Controller (ORC) system, it controls the side airbags in the event of an impact.
It is networked with other important control units in the vehicle via the PCI bus.
The module performs continuous self-tests and stores error codes in case of malfunctions, which facilitates diagnosis.
Each module, like the one on the left (LH), has a unique identification via a specific ground connection.
Why is the Chrysler Concorde LH airbag control unit defective?
A Chrysler Concorde LH airbag control module can malfunction due to internal memory corruption, communication errors on the data bus, or unremoved crash data after an accident. This often results in the airbag warning light activating and requires professional repair or replacement.
Common causes are internal memory errors (EEPROM) or calibration problems that lead to faulty system control.
After an accident, the control unit stores crash data, which requires a hard reset or reprogramming before it is fully functional again.
Communication problems with other control units via the CAN bus or internal software errors can also cause failures.
Voltage fluctuations or mechanical damage to the control unit itself are other possible reasons for a failure and make a Chrysler Concorde LH airbag control unit repair necessary.
Common error codes for Chrysler Concorde LH airbag control unit repair
During Chrysler Concorde LH airbag control unit repairs, specific B-codes occur that directly indicate problems with the airbag control unit. These codes often signal internal errors, communication problems, or the need for a reset after a crash, which requires specific diagnostics.
- B1000 → Control unit communication error → Internal error in the control unit or problem in the data bus.
- B1102 → Faulty crash data storage → The control unit has detected an accident and is locked.
- B1200 → Internal memory error in the airbag control unit → Corrupted EEPROM data or other internal hardware errors.
- B1300 → Communication error with other control units → Malfunction in the connection to the PCM or BCM via the CAN bus.
- B1400 → Pyro ignition circuit error (control unit detected) → Problems in the airbag ignition circuit that were diagnosed by the control unit, not the sensor itself.
What part numbers are available for the Chrysler Concorde LH airbag control unit repair?
For Chrysler Concorde LH airbag control unit repairs, several verified OEM and supplier part numbers are relevant to finding the right replacement part. These include specific Mopar numbers as well as identifications from major suppliers such as Bosch and Continental, ensuring precise compatibility.
Original Mopar part numbers are 56041028AA, 04861085AA and the replacement number 56041028AB.
As an OEM supplier, Bosch numbers such as 5WK43262 are also relevant, as Bosch produces these control units for Chrysler.
Continental also supplies components, so the number 0285001480 may indicate an OEM airbag ASIC/control unit.
It is crucial to match the exact part number because the modules are not repairable and only by replacing a matching unit can a successful Chrysler Concorde LH airbag control unit repair be achieved.
Where can I get my Chrysler Concorde LH airbag control unit repaired?
Your Chrysler Concorde LH airbag control unit should only be repaired by a specialized specialist or authorized workshop, as airbag systems are safety-critical components. These experts have the necessary diagnostic equipment and expertise to ensure professional and safe repairs.
Due to the complex electronics and safety implications, DIY repairs are not recommended and can be dangerous.
Professional workshops can correctly interpret error codes, reset the control unit, or replace it with a compatible spare part.
They ensure that all systems function properly after the repair and that the airbag warning light goes out.
Proper diagnosis and repair is essential to restore the full functionality of your vehicle's security system.
