Hi Dang
Sorry to have not got back to you sooner, error code 23 is a coding fault the module does not recognise what the truck is. Have you tried another module? In window one are you getting the correct truck details?
Error code 23 will give you the symptoms you have. If module is ok you may have a loom fault, check the plug into the module first then work back following the wiring diagram.
