Airbag control unit with part number 04602340AE

What is the function of the airbag control unit 4602340AE?

The airbag control unit with part number 4602340AE is the central control module for the occupant restraint system (SRS) in vehicles such as the Chrysler Stratus. It processes signals from acceleration and crash sensors and is responsible for deploying airbags and seatbelt pretensioners precisely and within milliseconds during a collision.

As an original Mopar OEM part, it serves as the brain of the entire restraint system. Its role is to continuously monitor all system components and activate life-saving safety functions in the event of a crash. Therefore, proper operation of this module is essential for passive vehicle safety.

This unit is also listed under the alternative designation 04602340AE and is technically compatible with related part numbers such as 4602340AD or 04602258AG.

Why does the control unit 4602340AE fail?

The most common cause of failure for the control unit 4602340AE is the storage of crash data after an accident, which triggers a safety lock on the system. Other causes include internal electronic faults—such as defective components, water damage, overvoltage, or disrupted communication with diagnostic tools.

Following a crash, so‑called crash data are stored in the control unit’s internal memory. This lock disables the airbag system to prevent unintended deployment due to subsequent damage. The SRS warning light illuminates, and the system remains inactive until professional repair or data deletion.

Beyond accidents, purely electronic failures can occur. These include defects in components like capacitors or circuit boards caused by aging, moisture, or voltage surges. Internal error codes such as 65535, B1000, or 93F9 often indicate hardware malfunctions.

How do you recognize a fault in the 4602340AE?

A faulty airbag control unit 4602340AE typically manifests as a permanently illuminated or flashing SRS airbag warning light on the instrument cluster. Additional signs include specific error codes stored in memory, issues with side or knee airbags, and a lack of communication between the control unit and diagnostic equipment.

The most obvious symptom is the active airbag warning light upon engine start-up, indicating that the system has detected a fault and may not deploy airbags in the event of a crash.

Another clear indication is when a workshop cannot establish communication with the airbag control unit using a diagnostic tool. The module fails to respond to queries, often pointing to a severe internal electronic malfunction.

In addition, specific error messages may appear, referencing problems with side sensors, knee airbags, or CAN‑bus communication—all directly caused by the control unit itself.

In which vehicles is the 4602340AE installed?

The Mopar control unit 4602340AE is specifically designed for Chrysler Group vehicles from the early 2000s. At Airbag24, we primarily service this component for the second-generation Chrysler Stratus (JA) as well as the technically related Dodge Stratus (JR).

Specifically, this part number is found in the following models:

How is the 4602340AE professionally repaired?

Professional repair of the 4602340AE at Airbag24 involves a systematic analysis to pinpoint the fault. First, stored crash data are erased and the fault memory is read out. Defective electronic components on the circuit board are then replaced, and the device is calibrated before being returned following a final test.

After submission to Airbag24, the control unit undergoes a standardized inspection and repair process. Initially, the fault memory is scanned using specialized diagnostic tools to identify the exact cause. Stored crash data are securely and completely removed.

If an electronic fault is detected, the circuit board is examined, and faulty components such as capacitors, processors, or other parts are professionally replaced. Following repairs, calibration and a comprehensive functional test ensure full operational capability.

We offer 2 years' statutory liability for defects on all repairs. Repairing is a cost-effective and sustainable alternative to expensive new purchases, as the original, vehicle‑specific unit remains intact.
