Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

• Visually inspect the cruise control switch/module. Sometimes, buttons are missing, cola has stuck the button in one position, buttons are loose and not making proper electrical connections. That’s why make sure that the buttons, that control the cruise functions, are freely moving and not contaminated with potentially damaging particles and/or dirt. You must also record all of the cruise functions' malfunctions or abnormalities
• Does the cruise control light come on in the instrument cluster when cruise is manually activated? If not, you may want to verify if there is a fuse for the circuit. This information should be found in the make and model service manual. Make sure to replace any blown fuses with top notch fuses online
• To access the harness to the cruise control switch/module, generally speaking, you will need to remove some dash parts (i.e. steering column shroud, airbag module in steering wheel, etc.). To pinpoint the specific wire involved in the fault, you will definitely need a proper wiring harness for your vehicle. These vary significantly, given many reasons. Always acquire proper service information before executing anything too invasive
• It would be a great idea to make sure your anti-lock brakes system is in good working order and no ABS light on in the dash. ABS use numerous sensors including speed sensors that, if malfunctioning, could fool the computers into thinking the vehicle is going faster or slower than the actual speed

Common Mistakes When Diagnosing The P0574 Code

• Most of the times mechanics make mistake of overlooking the blown fuse while diagnosing the P0574 trouble code
• Due to this the problem would not be fixed and the P0574 trouble code would return
