Just recently after starting up, the three lights (Traction Control, ABS and Hill Descent Control) remain lit (amber). As far as I remember, there are no associated warning chimes. It seems to happen when I've been parked facing uphill. Restarting on level ground clears the lights.

Any suggestions ?

TIA

 

Search Three Amigoes in this forum. You will find it is a prevalent problem with known solution

 

Shuttle valve ? So many threads on this.

 

Get the codes read from the OBDII port and you'll know where to start looking.

 

You do that only when the lights are on presumably ?

 

It depends on what fault caused the warning lamps to be illuminated. Some faults get stored for at least several drive cycles even if the fault is no longer present. You will need a code reader that reads ABS codes. Many read engine management codes only. Also, it's odd you get the Three Amigos without the warning chime sounding three times.

 

Spot on advice, thanks.

"Shuttle valve switch electrical failure"

But then you all knew that

Now off to find out if it's a DIY type job.

 

its a diy job. Should take less than 30 minutes

 

I read the links on the ABS Modulator sticky and I don't work that fast? It would take me that long to bleed the brakes afterwards! Perhaps I'm looking at the wrong place and that there is a faster fix that doesn't need the ABS modulator removing ?

 

No, it's not a 30-minute job. It's DIY-able, but it's going to take significant time and patience if you want to do it right and not just replace the shuttle valve. Do your homework, there are lots of resources.
