What is a Chrysler Stratus 1st Gen airbag control module?
The Chrysler Stratus 1st Gen Airbag Control Unit is the central safety unit that monitors and controls the entire occupant restraint system. It receives signals from sensors, stores crash and diagnostic data, and activates airbags and seatbelt pretensioners in an emergency to ensure the safety of the vehicle's occupants.
This module, also called the SRS module, is crucial for the vehicle's passive safety. It operates continuously and performs a self-test of all connected components when the vehicle is started.
Its correct function is essential because it decides within milliseconds whether the airbags are deployed in the event of an impact.
Why is the Chrysler Stratus 1st Gen airbag control module defective?
A Chrysler Stratus 1st Gen airbag control unit becomes defective because it stores crash data after an accident, requiring reprogramming. Age-related electronic failures, corrosion caused by moisture, or mechanical damage to connectors can also lead to malfunctions, necessitating immediate repair of the module.
Once an airbag is deployed, the control unit permanently stores so-called "crash data." This renders the module unusable until it is professionally reset or reprogrammed.
Internal hardware errors or power supply disruptions can also cause the airbag control unit to fail. In such cases, diagnosis and repair of the electronics is required.
Rust or moisture damage, often caused by leaks in the vehicle interior, can damage the sensitive electronics of the control unit. This leads to malfunctions or total failure of the airbag system.
Common error codes for Chrysler Stratus 1st Gen airbag control unit repair
When repairing the Chrysler Stratus 1st Gen airbag control module, specific B-codes often occur, which directly indicate problems with the control module itself. These trouble codes signal internal communication errors, memory problems, or malfunctions in the module's power supply, which require a precise diagnosis.
- B1000 → Control unit communication error → Internal defect or disturbed bus communication of the airbag ECU.
- B1001 → Airbag ECU internal memory error → Damage to the airbag ECU internal memory.
- B1002 → Error in the diagnostic interface of the control unit → Defect in the interface for read-out devices on the airbag ECU.
- B1003 → Control unit voltage supply out of specification → Incorrect on-board voltage or internal supply fault of the airbag ECU.
- B1004 → Internal control unit error → General hardware or software defect of the airbag ECU.
- B1013 → Internal EEPROM memory error → Incorrect read/write access to the non-volatile memory of the airbag ECU.
- B1021 → Communication error between airbag ECU and central control unit → Data transmission malfunction between airbag and main control unit.
- B1040 → Airbag control unit memory (ROM) error → Read-only memory integrity error in the airbag ECU.
- B1100 → Internal hardware error in the airbag control unit → Serious defect in the internal electronics of the airbag ECU.
What part numbers are available for the Chrysler Stratus 1st Gen airbag control unit repair?
There are no publicly verifiable OEM part numbers readily available for the Chrysler Stratus 1st Gen airbag control unit. Precise identification requires reading the number directly from the module in the vehicle, as the databases predominantly only list airbag modules or sensors, not the control unit itself.
The manufacturers Mopar, Bosch, Continental, and Siemens do not list specific control unit part numbers for the first-generation Chrysler Stratus in freely accessible catalogs.
This means that the exact part number of the required airbag control unit must be read directly from the nameplate of the removed module. A VIN query is often essential to validate compatibility.
Please note that common part numbers such as PJ42RC8 or MN25VK9AC are for airbag modules or sensors, but do not refer to the airbag control module in the first-generation Chrysler Stratus. The airbag control module is a separate component.
