RNessa weak battery
Summary of the thread
A 2001 Nissan RNessa is experiencing issues with a heavily discharged battery, flickering lights, and a weak engine start, with an error message displayed. The suspected cause is a defective battery sensor, which can disrupt the charging and discharge cycles, leading to battery drainage. A similar case was resolved by replacing the faulty sensor, and it is recommended to have the vehicle checked at a workshop for a proper diagnosis and repair.

Thanks for the input. Terminals look clean, and I've tried battery charging, but no luck. How was the issue solved on your car?

Right, cleaning the terminals and charging would have been the easy fix. In my case, the error memory pointed directly to a faulty battery sensor. Given your symptoms and troubleshooting, it's likely the same. A defective sensor messes with the charging and discharge cycles, causing the battery to drain even when it shouldn't. I'd recommend getting it checked out at a workshop. I ended up paying around 300€ for the repair.

Appreciate the confirmation. Taking it to the shop. Hopefully, it's just the sensor. Thanks for the help!

Hey, I had similar issues with my RNessa. Same symptoms – the flickering lights were the first thing I noticed. Have you checked the battery terminals for corrosion? Also, how old is the vehicle battery itself? A discharged battery can cause all sorts of weirdness with these electric systems. Could be as simple as needing a good battery charging.
