Couple things. First can you confirm which engine you have? You said it was a 0.6 but I assume you mean a 1.6L. Then the P1235 is not listed for this vehicle so are you pulling this code with a generic scan tool?
However, this code is for a fuel pump control circuit out of range so we need to check voltage at the driver module which should be under the front seat. I attached the wiring diagram, so let's check for 12 volts on pin 1 and then make sure the ground is okay on pin 4.
If the power and ground are good then let me know the voltage is on the other pins with the key on and we can figure out if the driver or pump is the issue.
Here is a guide that will help with this type of testing:

Let me know what questions you have. Thanks
