💡Problem Statement: When do You need the Service?

Airbag Module Replaced but Coding Cannot Be Completed?

After replacing the Airbag Control Unit (ACU/SRS), you require the correct vehicle configuration number (ACU Code) before the system can operate as intended. Without the valid ACU code, you can see airbag lights, DTCs, or features that don’t match the car. The airbag light will stay on or continue blinking.

Airbag Light Stays On or Blinks

The SRS module has been replaced, but the configuration has not been completed.

Variant Coding Error

Diagnostic tool reports Variant Coding, configuration, or similar coding errors. You may get a B1762 DTC.

ACU Code Requested

The diagnostic procedure asks for the vehicle's ACU/variant code.

Insights

What Is a Kia Hyundai ACU Code?

ACU stands for Airbag Control Unit. The ACU code, also commonly referred to as an Airbag Variant Code, SRS Variant Code, or Configuration Code, identifies the correct SRS configuration for a specific vehicle. It may define vehicle-specific equipment such as: Airbags, Seat sensors, Pretensioners, SRS configuration, Vehicle/market configuration. The correct configuration is especially important after installing or programming an airbag control module. You may need an ACU code in the following situations:

New Airbag/ACU module installation
SRS control module replacement
Airbag warning light after module replacement
ACU programming
Lost or incorrect variant coding
Variant Coding DTCs
Post-collision repairs

✅ Solution

How to Find Kia & Hyundai ACU Code from VIN?

If you have replaced your airbag module with a brand new one, after installing, you will need to enter and program the 4-digit ACU code using a scan tool; otherwise, you may get " Carriant Coding" or "ACU Coding" error. Kia or Hyundai ACU Code generators or look-up from VIN usually fail and give you an incorrect code, which then damages the SRS Module software permanently. We can provide a 100% correct ACU code from the VIN. We obtain the code from the manufacturer, which is the same as the dealer's. You can use it without any concern, wasting time, money, or damaging the ECU.

Step 1: Install the New Airbag Module
Step 2: Connect the Diagnostic tool (Autel, Launch, GDS, ...) and make sure you only have ACU coding error
Step 3: Make sure or components and wiring are fixed
Step 4: Send us the VIN and get the ACU code
Step 5: Enter the 4-Digit code and fix the light
