If you’re a Nissan owner, encountering the dreaded “Parking Brake Unavailable” warning alongside a “Front Radar Obstruction” message can be unsettling. These warnings can impact your safety features and overall driving experience. This article dives into the potential causes of these issues, offers troubleshooting steps, and explains when professional diagnostics and remote software solutions are necessary.
Understanding the “Parking Brake Unavailable” Warning
The parking brake, also known as the emergency brake, is a crucial safety feature. When it malfunctions, it not only affects parking but also other safety systems like hill start assist. Several factors can trigger the “Parking Brake Unavailable” warning. These include a faulty parking brake switch, a damaged parking brake cable, or issues with the electronic control unit (ECU). In some cases, a low battery voltage can also trigger this warning.
Troubleshooting the “Parking Brake Unavailable” Warning
First, check the parking brake lever. Ensure it’s fully released and not engaged. If it’s stuck, try gently wiggling it to see if it disengages. Next, inspect the area around the parking brake for any visible obstructions or damage. If the warning persists, check your battery voltage. A low battery can sometimes cause erratic behavior in electronic systems. If the battery voltage is low, charging or replacing the battery might resolve the issue.

Decoding the “Front Radar Obstruction” Warning
Nissan’s front radar system is a key component of advanced driver-assistance systems (ADAS) like adaptive cruise control and automatic emergency braking. The “Front Radar Obstruction” warning indicates that the radar’s ability to detect objects is impaired. This could be due to physical obstructions like dirt, snow, or ice covering the radar sensor, located typically behind the front emblem or in the lower grille. Other causes include sensor misalignment, wiring issues, or a faulty radar module.
Troubleshooting the “Front Radar Obstruction” Warning
The first step is to visually inspect the front radar sensor. Carefully clean the sensor area using a soft cloth and a mild cleaning solution. Avoid abrasive materials that could scratch the sensor lens. If cleaning doesn’t resolve the issue, check for any physical damage to the sensor or surrounding area. If you notice any misalignment, damage, or loose wiring, professional assistance is recommended.
