Failure to proceed

[ScottishGrenadier]

Grenadier momentarily refused to start this evening. Had been driving fine before I parked it up for 40 minutes or so but then just turned over without firing, sounded like an immobiliser issue. Locked it and left it a couple of times, after the 5th or 6th time it fired up and ran fine. I have experienced this once before with another Grenadier.

Anyone else had similar problems?

Is there a way to get codes off of OBD2 ?

I’ve had it happen twice in 24,000 miles. Didn’t throw any codes but nothing - zip. Turned the key back off and waited a couple minutes - started after a couple of tries. Still have no idea what was happening. Wondering if I was just in a hurry and didn’t have the brake pedal down as far as normal or something stupid like that.

Happened once to us parked outside a pub in Nova Scotia. No codes, had a good look around, couldn’t diagnose a fault. It started as normal 2 hours later.

Chalked it up as a pause-for-beer-before-getting-anxious type win.

Not a joke...

That is common across some cars. Why (but that is just a guess for the Grenadier)?

Radio legislation offers frequencies which are free. That means the manufacturer has not to register and run tests for a certain range of frequencies. In Germany these are 433 Mhz and 868 MHz (some more) and these are mostly use for remote controls of any kind. The drawback is, that the manufacturer has to accept problems. That is the price to pay for being able to use this frequency with no further effort and cost.

We already saw Range Rovers or Defenders (like the 110 of my wife), which rejected to start or open. It happend with a Range in front of my house, where we could force the immobilizer with the garage opener of my neighbour. My wife parked at a fuel station next to another car. When she returned the car didn't open. She called me for help and I started driving to her, In the meantime the car next to her left and everything was working again.

So check your environment. has something changed between not-working and working?

433,92 Mhz is the standard for cars within the European Union. It could be 315 Mhz for the US for the door opener and the immobilizer.

You can check the number on your key. It might read something like FSK (Frequenz Shifting Key) and a number.

You are a terrifying human being, @AWo. Maybe ChatGPT is just you, sitting there typing stuff.

No he's onto something. I reckon it's Automotive Havana syndrome. Check your environment

You can find that in the German "Frequenzverordnung FreqV" (Frequency Regulation).

The frequencies from 430 to 440 MHz are assigned to ham radio and non-navigational location finding use, code number D150.
Under D150 you find the following statement:
"Die Frequenzbereiche 9 – 10 kHz, 13 553 – 13 567 kHz, 26 957 – 27 283 kHz, 40,66 – 40,70 MHz, 433,05 – 434,79 MHz, 2 400 – 2 500 MHz, 5 725 – 5 875 MHz und 24 – 24,25 GHz sind für ISM-Anwendungen bestimmt. Funkdienste, die innerhalb dieser Frequenzbereiche wahrgenommen werden, müssen Störungen, die durch diese Anwendungen verursacht werden, hinnehmen."

Translation:
"The frequency ranges 9–10 kHz, 13,553–13,567 kHz, 26,957–27,283 kHz, 40.66–40.70 MHz, 433.05–434.79 MHz, 2,400–2,500 MHz, 5,725–5,875 MHz, and 24–24.25 GHz are designated for ISM applications. Radio services operating within these frequency ranges must accept any interference caused by these applications."

ISM stands for "Industrial, Scientific and Medical" applications.

The regulation on the European level are: 2019/1345 and 2014/53/EU

I have also seen multiple cars with the frequency issue, hopefully that is the issue because that means they will never just stop and not start when in the middle of nowhere
