Recently replaced battery because old one was tired and not holding voltage.  Car had sat for a while so on start up got tyre pressure warning light but dusturbingly  steering warning and traction control are now amber too.

Is this related to the tyre warning?

 

Never seen this before.

Did you drive the car? Lights normally go out after a few metres of driving.

 

Moved a few meters but no great distance,  I'll take it to get air in the tyers and see how I get on.  I'll put in correct pressure and set the mark.  No sign of puncture or damage. 

 

Ta Mate.

Try turning the steering wheel from full lock to lock, and driving back and forward a couple of car lengths.

Thank you Prezafab.

 

All suggestions are welcome, I'll give it a go in the morning.

 

Much appreciated.

I experienced two false tyre warning light episodes in the 5 years I owned my Yeti and I have had two on my present car a now 5 year old Audi A3. These things just happen.

As regards warning warning lights in general, these frequently occur when battery voltage is low or the battery has been replaced. Once a new/fully charged battery is in place then the dash and warning lights usually sort themselves out after a mile or so of driving.

Hi,

 

Got one of these within 24Hrs delivered to my door:-

Started first crank, so I'm hopefull things will be back to normal after a wee run.

 

Thanks.

 

 

Had this yesterday on my 2016 Yeti 4x4. Warning lights went out after a minute of engine running, except for tyre pressure light, which went out after a few hundred yards of driving. Lights stayed off for the rest of the 70 mile journey. Started up this morning, same lights on again. Stopped and restarted, just tyre pressure light flashed for a minute then stayed on solid. Handbook says fault in ABS/traction control/tyre pressure system, take to specialist. I'm guessing it is probably a faulty wheel speed sensor in the ABS system. Anyone know any better please?

Did you actually check the 4 tyres pressures and adjust and reset the TPMS?

Tyre pressures are all fine, pressed the TPMS button whilst driving home, but I'm not sure if it does anything if the warning light is off? Warning light stayed off all the way home (70 mile trip), and the whole illuminations thing started again this morning. Don't know yet if the tyre pressure warning light went out after the car was driven for a bit this time because the missus is still out in it.

Did you read the rest of this topic... Battery...?

Yes I did. Battery is fine. Its a stop/start model and that functions as it should. If the battery was low it wouldn't stop.

@SpeedIsYourFriend Resetting the TPMS requires the car to be stationary ignition on.

Always worth reading the Owners Manual. 

 

?

What does tyre pressures being fine mean?

When where they last set at whatever pressure when cold, was the cold then the same as cold now in the summer?

 

The warnings come as a different tyre circumference shows from the last time set.

That can happen with a wheel sitting in the sun and getting hotter, or a brake binding or a bearing overheating.

Basic stuff really.

Then low batteries can cause warnings for whatever and when ever.

I have read the owners manual.

I had already pressed the reset button with the car stationary and the ignition on, to no effect.

Tyre pressures fine means I checked them with an accurate tyre pressure gauge. I am obsessive about tyre condition and pressure.

As I understand it, the TPMS system monitors the tyre circumference using the ABS wheel speed sensors, and so it wouldn't trigger from just sitting in the sun until you actually start driving. The warning lights first appeared upon turning on the ignition and starting the engine after the car had been standing for a few hours. There were no problems on the previous journey.

We now have an error message on the MFD saying there is an ESC system fault. I will get it booked in to the garage to read the errors and hopefully it will just be a faulty wheel speed sensor.

I don't have an OBD reader myself, maybe I should buy one? What would you recommend?

I wouldn't be so dismissive actually. If you have a C-Tek charger already, put that on. From experience with two of our eight Yetis 🤗

Hi

 

From what I can glean, these TPMS systems only work on the ratio between the different tyre circumferences.  They have no idea what the absolute value is.  So if they all increase or decrease by the same amount no warning will be triggered.  The situation they are looking for is one tyre rotating consistently at a different rate to the other three.  Presumably the results have to be averaged out for long enough that cornering doesn't trigger a warning, so when you set off you may not get a warning straight away.

 

As for low battery voltage giving warnings, surely the electronic design should be robust enough to cope with such things unless the battery is completely knackered ?  The supplies to any electronics should be well filtered and regulated down from the raw 12 volts. We don't hear tales of the ECU failing to start the engine when the battery voltage drops to as low as 9 or 10 volts during cold cranking.

'Shirley' was off that day at the Engineering meeting so what you have is what you have and that can be warnings.

Hi,

 

The warning symbol did go away after a few hundred meters.  However I did pump the tyers up and they did need inflating.  No recalibration required!

@Davroz Sorry what do you mean, are you saying you did not need to ot just did not reset the TPMS after putting air in the tyres? 

Hi,

 

The were only a few PSI out and the TPMS did reaapear or need setting.

So did that mean the TPMS light came on so you checked and adjusted the tyres to the correct pressure before resetting the TPMS?
