1. Installation instruction

The installation is a simple process. Follow the instruction below:

1. Before fitting the emulator scan your car with a diagnostic scanner (for example: the Star Diagnosis) to verify you have defective passenger seat mat fault code and there are no short circuits or open circuits. Take a photo, it might be helpful in the future.

2. Turn the ignition off.

3. Find the seat occupancy sensor plug under the passenger seat. Below you will find a photo/video with a location of the plug.

4. Disconnect the seat mat plug and replace it with the emulator's plug.

5. If your car is equipped with an unfasten seat belt warning system, now you can also connect the seat belt emulator.

6. Connect again the diagnostic scanner and reset your old fault codes. The defective passenger seat mat error should not be present anymore and the SRS light should go off.

The fault code (or the SRS light) is still present. What should I do?

Do not worry. We will help you solve the problem but we need more details about your current situation in order to learn what is the root cause of your problem and provide the best solution. Please send us the following informations:

Step 1. Check if the LED light on emulator blinks alternately blue/green or red/green light (depends on the emulator, check the information on the sticker). No blinking lights or one color missing mean there is a problem with proper communication with the ACU or there is no power (+12V) sent to the emulator.

Step 2. Connect the diagnostic scanner and take photo of all fault codes you have and their descriptions. Remember that this photo is for step 2.

Step 3. Turn the ignition off. Disconnect the emulator, but do NOT connect anything. Reset the fault codes and read new fault codes. Take a photo of all fault codes and remember that this photo is for step 3.

Step 4. Turn the ignition off. Now connect your original seat mat plug. Reset the fault codes and read new fault codes. Take a photo of all fault codes and remember that this photo is for step 4.

If the fault codes are the same in all steps then you have the Airbag Control Unit broken. This problem is not connected to a faulty seat mat and the emulator will not help you with that problem. If you have different fault codes on every step, then send us all photos to the email address listed HERE.

We need ALL photos to do a proper diagnosis of the problem and give you a proper solution.

The fault codes disappeared but the SRS light on the dashboard is still present and now started to flash. What should I do?

If the fault codes are not present anymore but the SRS light is flashing it means your Airbag Control Unit (ACU) is opened for programing and needs to be closed manually. The ACU sometimes opens itself when there is a problem with the SRS (like broken seat mat). In order to Close / Lock SRS Airbag Control unit you need the Star Diagnosis. You will find the step-by-step instruction how to lock the ACU HERE.
