What does the P0564 cruise control input circuit malfunction mean?
2 Answers
P0564 cruise control input circuit malfunction is usually caused by issues with the cruise control switch or wiring problems. It is necessary to first check the wiring for any faults. If no wiring issues are found, simply replacing the switch should resolve the problem. Below is a detailed explanation of the P0564 trouble code: Definition: The P0564 trouble code, applicable to all automobile manufacturers, refers to the Cruise-Control-Multi-Function-Input-A-Circuit. Clearing the code: After troubleshooting and fixing the issue, the trouble code must be cleared. When clearing the trouble code, it is essential to strictly follow the specific clearing method designated for the particular vehicle model. It is important to note that the negative battery terminal should not be disconnected arbitrarily to clear the trouble code.
The fault code P0564 on your car indicates an issue with the cruise control input circuit. Let me explain—the cruise control system relies on this input circuit to receive signals. If this circuit malfunctions, the system may fail. With years of repair experience, I can tell you the most common causes include short circuits or open circuits in the wiring, such as aged or damaged wires, loose or oxidized connectors, or improperly seated plugs. It could also be due to a burnt-out relay or worn switch contacts, which prevent signal transmission. Sometimes, voltage instability can trigger the issue as well. For troubleshooting, start by opening the hood to check if the relevant fuse is blown. Then, use a multimeter to test whether the circuit voltage is normal. If you can't resolve it yourself, head to a 4S shop or professional repair station immediately. Remember, cruise control helps save fuel and reduces driver fatigue, so fixing it early can prevent accidents or delays on the road. This fault isn’t uncommon, and the repair cost isn’t high, but don’t delay too long to avoid affecting other components.
