Nissan Qashqai - System Fault

[Scarletpimpofnel]

Nissan Qashqai petrol 1.3 2018 suddenly developed a system fault yesterday. No OBD II error codes. Thought it might be the battery as only 11.75Volts at rest (replaced with official stop/start battery for the car). But fault remains.

Fault pages are as below. Note also TMPS seems to be only measuring on one side. Haven't driven the car since changing the battery but starts and faults still there.

Stop/start seems disabled (both before and after battery change).

Any ideas on root cause? Many thanks.

Reset the tpms system and take it for a drive as it wont display the pressures until its been driven for a while.

For some reason I want to say that the error looks to be something to do with the radar for proximity, lane keep assist , reversing camera. But that might be because you are cycling through those options.

Just did 20 mile drive. Tpms measures ok once moving.

Good call. Could it be possible a radar sensor or fuse has blown and that’s causing all the issues?

First thing I’d do is clean the camera and sensor in the badge at the front of the car.

Ok thanks will try that.

I cleaned the badge (no change). I can see a cable goes to the badge from behind but the badge itself doesn't seem to dismantle to give access to any camera or sensor.

I used to work for Nissan. I think it might be the rear proximity sensor. It is a known fault but I don’t think you can fix it without replacing it.

Is that one of the 4 sensors in the bumper?

at this point i'd say your best bet is to take it to a Nissan dealer and ask them to investigate. They can either fix it for you, or they can tell you which sensor it is and you can have a go yourself. Anything else and you'd be guessing, you might get lucky, but the chances are you'll spend more money throwing parts at it until you fix it.

Yep I thought it was the battery (was readin 11.7V at rest) so replaced that but nothing else I can do has worked. No OBDII codes. So it'll have to go to a dealer.

Thanks all for your suggestions.
