This morning after a hard acceleration the abs light came on along with the tcs.
What can it be?

 

The freakin' cars are possessed by gremlins, I shit you not !
Did the lights go back out.....or did the ABS indicator lamp stay on ?

 

It stays on.

 

Hey 1st timer, for shits and giggles....check the fuse labeled "R/C Mirror" (7.5a) which is located in the driver's side fuse panel. Then next check the fuse labeled "Back-up Light" (7.5a). Could be an aftershock of the alternator, as this can create many nuisance problems due to low or fluctuating voltage. It sucks !

 

The alt was changed on Monday!

 

and that means its working today because.....

did this involve spinning of the wheels at low speed- under 25Kph with active TCS
ie: uses brake on spinning wheel in pulses similar to ABS active

reset the ECU via clock fuse removal method,,see if it comes back

 

yes ,i spun the wheels under 40km/h with the tcs active. I disconnected the battery for 2-3 mins and when i reconnected,it came back on.

 

I checked the 30A fuse thats for the ABS under the hood and it's burnt!!
Thanks god its only a fuse.

 

Now you have to wonder why it Burnt...

 

That's what i was thinking of!! Could it be that my alt wasn't working properly for a while?
Or because of too many hard accels under 25kkm/h with tcs activated?

 

I changed the fuse and the light was still on along with the tcs light.
I changed the tcs fuse and still nothing happened.
As i drove off, both lights shut off!!

 

did you reset the ecu via clock fuse removal method?

 

Yes I did.
