Have you used the service check connector to trigger the display of error codes? Model year is always a useful detail because the systems did change during the production run.

Thanks for the reply and yes this is diagnosis mode i have it jump and this is the code indicater giving me, I am so confused beause I can't match the code from the list or I just don't know how to read it.

You obviously have a non North American market car so you really need to consult the market specific service manual.

With the service check connector disconnected, does the TCS light stay on or does it go off? On the ALB / TCS systems, the warning light coming on and staying on with no blinks can be an indication of low voltage. It looks like the ABS turns off normally and the TCS light turns off once you start the car? If that is correct, I would check your battery voltage and check the battery connections and the connection to the TCS module.

Your CEL is staying on which is a sign of a stored code. Try erasing the code in the ECU to see if that makes the CEL go away. You could also try erasing the stored codes in the TCS (different fuse) to see if that clears the problem after check the battery voltages and connections.
