Frequently Asked Questions
Why is the Hill Descent Control Light on in my Nissan 370Z?
The Hill Descent Control Light illuminates on a Nissan 370Z when the vehicle detects a condition in the related system that is outside its normal range. The exact reason can vary from something as minor as a loose connection to a component that needs replacing, which is why reading the stored trouble codes is the reliable way to know for certain.
Can I keep driving with the Hill Descent Control Light on?
It depends on the urgency (low) and how your Nissan 370Z is behaving. If the light is red or flashing, or the car drives differently, stop safely and get help. If it is amber and everything feels normal, you can usually drive to a workshop soon — just do not put off the diagnosis.

Cost varies widely because the Hill Descent Control Light can stem from several causes on a Nissan 370Z. Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour.

Will the Hill Descent Control Light reset itself on a Nissan 370Z?
