Airbag control unit with part number 13585615

What is Airbag Control Unit 13585615?

The airbag control unit with part number 13585615 is the central control module for the occupant protection system in the Opel Ampera A (Type D1JOI). It processes signals from crash sensors and, in the event of a collision, deploys the airbags and pretensioners to protect vehicle occupants.

This unit, also known as the SRS module (Supplemental Restraint System), is responsible for continuously monitoring all safety‑related components of the airbag system. These include the various airbags, seatbelt pretensioners, as well as the acceleration and pressure sensors installed in the vehicle.

Part number 13585615 is one of two verified original OEM numbers for the Opel Ampera A. The alternative, equally original part number is 13584904. Both control units perform the same function in the vehicle.

What Defects Can Occur with 13585615?

Defects in control unit 13585615 typically manifest as stored crash data after an accident or internal electronic hardware failures. Common causes include faulty memory chips, power supply issues, or physical damage such as corrosion due to moisture ingress.

Following a crash, accident data—known as crash data—is permanently recorded in the control unit’s memory (EEPROM/Flash). This lockout disables the entire airbag system and prevents re‑deployment until the data is professionally erased.

A frequent defect is an internal electronic failure on the circuit board. Error codes like “control unit defective” indicate problems with components such as malfunctioning memory ICs, driver stages, or poor solder joints. Such faults may even occur spontaneously without any prior accident.

Due to its installation deep within the vehicle, penetrating moisture can lead to water damage. Corrosion at connector contacts and short circuits on the circuit board are common consequences, potentially resulting in complete failure of the control unit.

How Do You Recognize a Defect in Control Unit 13585615?

A defect in airbag control unit 13585615 is unmistakably signaled by the permanently illuminated airbag or SRS warning light in the instrument cluster. Additionally, specific fault codes stored in the airbag system’s error memory can be read out; these codes cannot be cleared manually.

The primary and most obvious symptom is the persistently lit airbag warning lamp. If this light does not extinguish after starting the vehicle, it clearly indicates a serious system fault—often originating directly from the control unit itself—and necessitates deactivation of the system.

When using a diagnostic tool to read the error memory, fault codes appear that point directly to the control unit. Typical entries include “control unit defective,” “internal error,” or indications of stored crash data that cannot be erased through conventional means.

In some cases, complete communication breakdown may also occur. In such situations, the diagnostic tool is unable to establish a connection with the airbag control unit, making further fault analysis inside the vehicle impossible.

How Does Repair of 13585615 Work at Airbag24?

At Airbag24, repairing control unit 13585615 follows a standardized process: Upon receipt, an initial inspection verifies the nature of the fault. Subsequently, crash data is erased, or electronic components on the circuit board are repaired, and the unit undergoes testing on a dedicated test bench.

First, a qualified workshop should read out the error memory to confirm whether the defect truly originates from the control unit. After proper removal, the unopened device is securely packaged and shipped to Airbag24.

Our technicians conduct a detailed analysis. If the issue involves stored crash data, a reset is performed, returning the control unit to factory settings. Should a hardware defect be present, faulty components such as memory chips or driver ICs are replaced, and solder joints are reworked.

Finally, each repaired control unit undergoes comprehensive functional testing on a specialized test bench, ensuring correct communication and full operability. We provide 2 years' statutory liability for defects on every repair.
