OBD-II Generic Error Code P1564: How to Fix It (Nissan ASCD Steering Switch)

Q: Can I still drive my Nissan with a P1564 code?

Yes, in most cases your vehicle will drive normally with a P1564 code stored. The primary symptom is that cruise control (ASCD) will not engage or function. However, you should still address the fault promptly, as ignoring electrical faults in the steering wheel area can mask other issues and will cause the vehicle to fail an emissions inspection in many states.

Q: What is the most common cause of P1564 on a Nissan?

The two most common causes are a failed ASCD steering wheel switch assembly and a worn or broken clock spring (spiral cable). The clock spring is especially common on higher-mileage vehicles because it experiences stress every time the steering wheel is turned. If your horn also stopped working or your airbag warning light is on alongside P1564, a faulty clock spring is very likely the root cause.

Q: How much does it cost to fix a P1564 Nissan code?

If the ASCD steering switch itself needs replacement, parts typically range from $30 to $100 for aftermarket options, with DIY labor. A clock spring replacement typically costs $50 to $150 for the part; professional labor adds $100 to $200 depending on the shop. At a dealership, expect to pay $200 to $450 total for clock spring replacement including diagnosis. Simple wiring repairs can be lower cost, while ECM-related faults may be significantly more expensive.

Q: Will P1564 cause my car to fail an emissions test?

In many states and jurisdictions, any stored OBD2 fault code that illuminates the check engine light will result in a failed emissions or smog inspection. Even if P1564 does not always trigger the check engine light on every Nissan model, you should resolve the code before any required vehicle inspection to avoid failing.

Q: How do I know if my clock spring is bad on my Nissan?

Common signs of a failed clock spring include: cruise control buttons not working (P1564), the horn not working, the airbag warning light illuminating on the dashboard, and steering wheel audio or phone controls becoming intermittent or unresponsive. If you notice two or more of these symptoms together, the clock spring is the most likely culprit and should be inspected or replaced.

Abstract

Error code P1564 is a manufacturer-specific diagnostic trouble code (DTC) that appears on Nissan vehicles and indicates a fault in the Automatic Speed Control Device (ASCD) steering switch — the cruise control buttons located on your steering wheel. When the vehicle's ECM (Engine Control Module) detects an abnormal signal or no signal from these switches, it stores P1564 and may disable cruise control functionality. In most cases, your vehicle will still drive normally, but cruise control will not engage until the fault is resolved.
