Keep reading as we discuss these possible suspects to the persisting 4WD light on your Nissan Titan in greater detail. We’ll also share the potential solutions to these underlying issues for your convenience.
What Causes The 4WD Light On The Nissan Titan To Stay On?
A persisting 4WD light on a Nissan Titan typically comes from a fault from either a fuse or a bad battery. Although solving these underlying issues is usually a DIY-friendly job, it's still important to understand why the error happens. That way, you might be able to prevent the problem from resurfacing.
Automotive fuses help vehicles, including your Nissan Titan, in reducing the electrical current flowing through different systems. These components are like your home's circuit breakers that aid in preventing harm to connected assemblies and parts in the event of overloads or short circuits.
A fuse malfunction or breakdown may also become the suspect to your Titan’s 4WD light remaining on, even after disengaging the engine. Replacing the faulty fuse could solve this problem.
Purchasing a low-quality battery may help you save money to power your Nissan Titan. But the subpar properties offered by the poor power source may cause errors and glitches in the pickup truck. Aside from the 4WD light staying on, other side effects of installing a bad battery to a vehicle may include:
- Slow start
- Failure to start
- Heavy corrosion
- The frequent need for jump starts
- Clicks, cranks, and other sounds coming from the engine
