Lights on Dash

[Dblock]

Hi Guys,

 

My lights are coming on the dash, traction, slip, abs and the other ones.

 

Now it isnt storing the code so I cant read it. I have changed my tyres to 225/40/18 but before I was running 235/40/18. Its also not just the slip light thats coming on. It might be that but is there anything else it might be before I check the tyres?

 

Abs sensor or low brake fluid maybe? Changing the tyres will be my last resort so please dont mention that first or say well this is why... Anything I can check before this?

 

Thanks

Battery?

Zeds do crazy stuff when the batteries are shagged

Especially with the baltic weather moving in recently.

 

Could be some crud on the sensor too.

Good point as the decats was taken off and then put back on for the MOT but I thought that it would log a code

My car had this last winter, ABS light,slip light etc etc it turned out to be a switch in one of my brake lights so when I was braking the ECU got confused as the brakes obviously came on but didn't tell the ECU!!

 

Just a word of warning, when all the lights show you have NO electronic help so take it easy

Mine didn't throw an actual fault either...

[Dblock]

Thanks guys. I guesss it's a process of elimination

 

Will report back

Yeah I was worried it was an ABS fault and thought it would be expensive, but it turned out to be a£15 switch hope yours is as simple

Took the car out today the lights came on when I was on the dual carrigeway. The battery isn't too bad but Il stick it on charge anyway.

 

Il check the brake switch but I dunno I got a feeling it's abs related. As they changed my tyres and I asked them to look about fitting bushes. Il check the switch aswell though as it can't hurt.

One of 2 things, Firstly check brake switch by unplugging and checking for green corrosion. If its not this and only happens when braking it have the the module under the steering wheel that deals with traction and ABS.

The lights come on the dash when your driving on the dual carriage. Doesn't come on when you press the brakes. First they flash super quick like blink and you miss it then the lights stay on.

Have you checked your brake fluid level?

 

I ahd the same and checked the fluid level and that was low... however I checked my pads before topping up and they were low too so replaced and the fluid level retuirned to almost normal and no lighty.

[Dblock]

Didn't get to much of a chance to poke around. So far I've charged the battery. It was fine but left it to trickle charge for 1 day. Checked brake fluid it's full.

 

Going to check what Lee suggested but it only seems to do it on the motorway.

Tyre sizes are the likely cause here, the rolling circumferences between front & rear are different so the ecu thinks the wheels are slipping

I get that the traction control might think its slipping when its not but surely all the lights wouldnt come on?

[Darren-B]

I generally drive mine with the ESP off

 

But for example, in the snow last year I had it on trying to navigate a slight incline on the motorway, tc was trying its hardest then all lights came up (ESP & abs)& I had no aids, blew the fuse. Have you checked the fuses?

Good idea il check the fuses. Its just it comes on when going straight in a line usually on the motorway. But when I start the car drive it around its fine for abit then all the lights come on again.

WhAt tyre sizes are you running both front & rear?

[Darren-B]

Stock tyres sizes

Front 225 45 18Rolling circumference 558

Rear 245 45 18 rolling circumference 567

[Dblock]

I was running 235/40/18's on the front with no troubles though. If i do get more tyres they will be 235/40/18

[Darren-B]

I meant diameter in my last post rather than circumference ,

 

What size tyre are you running on the rear? If the offset of diameters is not within 10-20mm the car will read the wheel speeds differently thus tripping the lights

 

For example the stock sizes:

Stock tyres sizes

Front 225 45 18 Diameter 558 Rolling circumference 1753

Rear 245 45 18 Diameter 567 rolling circumference 1780

 

Your old tyres:

Front 235/40/18 Diameter 563 rolling circumference 1767

Rear????

[Dblock]

245/45/18 rear and 235/40/18 with 100% no problem.
