How to factory reset nissan primera SVE 2003 ECU

You need the body control module tested for fault codes.

Check your manual or go to AutoZone website, free manuals on there.

2003 Nissan Primera, the P12 engine runs on chain NOT belt!!! You don't need to change the chain unless in very very unlikely case the chain snaps.

What does SVE stand for in NISSAN

It has a timing chain.

parts store

check wiring connection and fuses inside the bonnet. it is loose conection

I believe the only way is to use an OBD II reader. Many auto parts stores have these and will read your error codes for you (usually no charge). I do not know if they will reset the codes for you as I do my own.

The most likely cause of most problems electrics on that model is the poor earth connection on the rear light cluster. There is a simple fix which you can find on the nissan primera owners club website. www.npoc.co.uk. The fix is easy to do and involves putting another earth from the rear cluster to the bodywork where there is an existing bolt. It solved my issues.

The problem is that your sunroof is operated by a PCB which contains computerized programmed IC.  This problem is not with battery.  You might have been operating your sunroof when your battery was down.  The programming of IC has been disturbed.  Take that PCB to the service centre.

Always operate your power windows/side mirror/ sunroofs when your car is start because these power stuffs have high rated motors.

When the car is start it's load is on genrator/dinamo therefore it does n't have any effect on battery.

mail me, if you would like to ask any thing else.
