Stop Start issues

Post by Lollie » Wed Jul 21, 2021 11:26 pm

Hi, I see this question has been asked before however I can't seem to find the route of my problem. My battery died and has just been replaced at the garage however, I need some help. I keep getting the message stop/start system fault appear with the auto symbol flashing. I have managed to clear the warning message but auto is still flashing. Most posts seem to indicate that replacing the battery will clear this issue but it has not. The stop start button does not seem to do anything either? It does not light up, and I'm sure it did previously, although I could be wrong!

Any suggestions would be greatly appreciated. Thanks in advance.

Certain conditions may prevent Stop/Start working and related to your battery change.

1. A battery other than the stop/start system-specific battery is used.

2. To use the stop/start system, the vehicle needs to recognize the status of battery. For this reason, the stop/
start system may not be activated immediately after battery change.

The new Battery may not be to the specification required by your car. Certain parameters are sensed...discharge etc. Items 1 & 2 above apply.

The vehicle needs to be checked for error codes (DTCs) to accurately identify the problem.

Welcome to this forum

Was the battery fitted at a Nissan garage?

Do you know what battery has been fitted?

Thank you for your reply. The battery was replaced by my local garage who sourced the best battery for the job. I will pop in for a chat and ask them to check for error codes.

Thanks for your suggestions and help.

Thank you Gloucester.

The battery was fitted by my local garage who I have always found to be very reliable and helpful. I'm afraid I don't know what battery was fitted but I believe they would have sourced one up to the task and for stop/start.

As suggested in another post, I will ask the garage to check for any error codes.

Thanks for your post.

Hi calnorth, I forgot to ask, when you say the stop/start may not start immediately after a battery replacement, do you think the flashing auto light could rectify itself over time and if so, on what sort of timescale? Is it perhaps a case of the system having to learn that the battery is new? Sorry if I am being a bit dim (unlike the flashing auto light on the dash!!). I'm new to having a car with stop/start functionality.

Thanks again.

From what I can remember the Battery is monitored as regards discharge and charging. Diagnostics doesn't give the number of times this is done, starts and running cycles. I suggest it must meet specific values (constants) pretty quick. Until then Start/Stop cannot be enabled because the Battery isn't confirmed as adequate? May fail Auto Stop/Start on the road....... :oops:

Also, a new battery is registered to the car, such that old monitored history is deleted/reset. As I understand it the age/behaviour of the Battery is tracked and charging for instance is adjusted for age. I have seen the RAC configure the system on my warranty Batt change. The Battery fitted was a VARTA AGM SS type which is dead right for the car.

I could well do without the SS nonsense actually.

Thanks for your further comments calnorth. When I speak to the garage I will show them the comments yourself and Gloucester have made.

I will update when I have any information.

Fingers crossed 🤞

SS can drop out (fail with warnings) for a number of reasons....Battery, ABS, Body Control and Fuelling (Exhaust commonly). All safety and emissions related.

Yes...we'd like to know the outcome.

Hi calnorth and Gloucester. Been to the garage and it was just a break down in communication with their guys, they had forgotten to check and clear the error code. A few minutes with the reader plugged in, it was cleared. Had it out for a run yesterday and the stop start is working nicely.

Thanks for all your suggestions, very helpful indeed.
