P0564 - OBD Trouble Code

<<See All OBD Codes

Does your cruise control switch face damages often? Is there shorted circuit to your cruise control switch? Are there any electrical issues? If you see all these symptoms, then it is more like that your engine may show up *0564 error code. The body control module operates the cruise control system. The driver input to the body control module is monitored by the cruise control system which sends request to the engine computer (PCM). If the body control module, senses a void input from the cruise control switches, then the error code, P0564 will be found.

The cruise control system will keep the vehicle running at a stable speed till it receives a cancelling signal. Turning on the main switch and keeping the vehicle in running mode, the battery voltage is sent to the engine control module (ECM). When the vehicle is in a state and a signal is sent from the control switch to the ECM, the ECM will control the fuel injection in as to make the car go steadily at a preferred speed. Also, you can see the lighting of the cruise indicator lamp in the meter assembly while you operate the system. The ECM will monitor the cruise control switch signal and if it is not up to the factory specification, then the OBD II code will be set.

What causes this problem with the Cruise Control Multi-Function Input "A" Circuit?

• The most common cause for this problem is a faulty cruise control switch.
• At times there might be an opening or shorted circuit in the cruise control buttons (mostly due to the spilling of fluids on the cruise control components).
• Electrical issues can rise up if there is a shorted or open wiring, rusted connectors and blown fuses.

1. Cruise Control Switch - A broken or damaged switch has to be replaced immediately so that this error code can be avoided.
2. Body Control Module - A faulty or defective body control module needs immediate replacement for the system to function normally.
3. Cruise Control System - Do you face any issue in your cruise control system? Visually inspect them and get the parts repaired.
4. Engine Control Module - Is your engine control module faulty? Are there any damages? Get them replaced with the right replacement part from Parts Avatar.
5. Fuel Injection - Leaks / broken/ damaged fuel injector needs immediate replacement.
6. Cruise Control Connectors - A broken connector has to be replaced so that the system can function normally.
7. Blown Fuses - Is your fuse damaged or defective? Replace with new ones as mentioned by the manufacturer from Parts Avatar.
8. Cruise Control Straps - make sure that the straps of the system are in best condition. If not get them replaced or repaired.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0564 here:

Common Symptoms

• The vehicle speed will be abnormal with active cruise control.
• Defective cruise control.
• Cruise control light will be well lit regardless of the switch’s position.
• Impossible to set the preferred speed for cruise control.

Here are some ways with the help of which you will be able to correct the OBD Code P0564:

• Here are some ways with the help of which you will be able to correct the OBD Code P0564
• Initially, the mechanic will test the vehicle with the help of a scanner, reset the faulty codes and test drives the vehicle to see if the code appears again.
• Secondly, he will inspect the electrical connections related to it, in order to make sure that they are in proper working condition, without any faults, corrosion, short or separated wires and components. If you come across any issue, they have to be repaired and re-tested. If the code still appears there can be a fault in your cruise control switch.
• Replace with a new switch and test drive to see if it functions. Retest the code even it is operable or not. If the system does not function and the code still exist, then you have to lift the vehicle and test run it at 25 mph. While you operate the vehicle and test it for voltage you have to disconnect the cruise controls electrical connector. If it satisfies the specification by the manufacturer, disconnect both the PCM and cruise control module to test the circuit between the switches.
• If the code still exists, then you have to do a resistance test on the cruise control power switch and button, because this can be the final reason for your code to appear.

There is no need to be anxious as Parts Avatar – Car Parts Online is here to help you out! We have high grade Cruise Control Switch, Body Control Module, cruise control system, Engine Control Module, fuel injection, connectors, blown fuses, straps and a lot more for our precious customers.

• The error code is diagnosed with a OBD-II scanner, and you have to look through the freeze frame data in order to check when the code re-appeared. The mechanic will now reset the codes and test drive the vehicle to see if the system functions properly and the codes appear again.
• If the code appears again, he has to visually inspect all the related components like connectors, wires and straps. If there is a need for any replacement or repair, it has to be fixed and the system has to be reset. If the code, appears once again, then the switch has to be changed.
