If you own a Nissan vehicle and have encountered the dreaded “Check Engine Light” on your dashboard, you might wonder what could be causing the issue. One reason for this “check engine light” is the P1564 code.

The P1564 error code can come up in your Nissan Murano or any other Nissan vehicle. This means there is an issue with the Automatic Speed Control Device, also known as the cruise control system.

Issues with the Fuse, ASCD switch, wiring, or Engine Control Module issues can cause this P1564 error message.

Here are the details of the P1564 Nissan code, its potential causes, symptoms, and the steps you can take to diagnose and resolve the issue.

What is the P1564 Code?

The P1564 code is a diagnostic trouble code (DTC) in Nissan vehicles. It is related to the Automatic Speed Control Device (ASCD). The ASCD is otherwise known as cruise control. 

This error message may seem slightly different depending on your specific Nissan model.

The “P1564” code may be displayed alone or in conjunction with other letters and digits in some vehicles. No matter the Nissan vehicle you drive, where there is a P1564 code, the most likely scenario is an issue with the cruise control system.

The cruise control system is a complex assembly consisting of multiple components. A thorough check is necessary to identify and address any specific issues with the ASCD accurately. Each component’s functionality must be examined to pinpoint the root cause of the problem that requires resolution.

What is the Symptom of Error code P1564?

The most common symptom associated with the P1564 code is the Engine Light On. The most typical and easily recognizable sign is when the “Check Engine Light” comes on in the dashboard.

The P1564 code and the accompanying warning light come on the dashboard when an issue is detected with the cruise control.

Several factors could trigger the P1564 code in your Nissan vehicle. Some of the common causes include:

Malfunctioning ASCD Switch: The ASCD switch is a feature in your Nissan car that allows you to set a desired speed for your vehicle to maintain without pressing the accelerator pedal continuously.

When the ASCD switch malfunctions, it means that the cruise control function may not work correctly or might not work at all.

Long trips on open roads are made more tedious by the inability to employ cruise control due to an ASCD switch that needs to be fixed. However, getting it checked and repaired by a qualified mechanic or dealership is essential. They will diagnose the issue with the ASCD switch and fix or replace it, allowing you to enjoy the benefits of cruise control.

Broken Wiring or Clock Spring: The wires and clock spring that connect the ASCD steering switch to the rest of the wiring may get damaged or break. This problem mostly happens because an earlier repair involving removal of the steering wheel wasn’t done right.

If the clock spring is not rightly placed, it will be overworked and break. The only way to know for sure is to use a voltmeter to check the voltages. A broken clock spring can also cause problems with things like the horn in the car.

Faulty PCM: The PCM is also known as the Powertrain Control Module. It acts as the brain of your car. It controls the whole cruise control operation. If you notice a significant drop in engine power and acceleration, it might be due to the faulty PCM.

You might notice that the engine does not run as smoothly as it used to or struggles to perform optimally. If so, it might be due to a faulty PCM.

How to diagnose Nissan Vehicle Error Code P1564

Below is a well-detailed method consisting of 10 easy-to-follow steps to safely diagnose your Nissan Vehicle.

Step 1: See if there are other codes: Start by using an OBD-II reader to see if the Engine Control Module (ECM) has any other codes. More codes tell you important things about the car’s overall state and help narrow down the problem.

Step 2: Visual Inspection: Look at the parts of the ASCD system, such as the cruise control switch, wiring harnesses, and connections. Check for any damage, loose links, or other signs of wear that you can see.

Step 3: Test the ASCD switch: The ASCD switch is an important part of the speed control system. To ensure the switch works, press the cruise control buttons on the steering wheel and watch the screen to see what happens. If the ASCD switch doesn’t respond or acts strangely, it may be broken and must be replaced.

Step 4: Look for problems with the electric power: Check the ASCD system’s wire harness and connection points. Check for connection and make sure there are no open or short circuits that could stop the cruise control from working as it should.

Step 5: Look for Data Parameters: Use a professional diagnostic scanner that can get real data parameters. While the vehicle is moving, keep an eye on the data linked to the ASCD system. Look for any differences or numbers that aren’t in the normal range. This could mean that there are problems with the sensor or actuator.
