ASR warning light.

When I skidded on some ice the ASR warning light came on and stayed on for about 100 miles. Is that normal?

Main cause of light staying on is allegedly a battery fault or failing battery. ASR is controlled (I believe ) through brake switch which in turn is inputting to other areas e g ABS and I assume that poor battery response can affect all this.

You should maybe have pulled over and switched the ignition off for a period to see if that reset it ?

I have a Toyota C-HR which seems to have a lot of these types of safety things, ASR, sign recognition, collision avoidance, lane departure. If something does activate it can take a while (not 100 miles) for the system to decide to reset properly. It won't be battery since the car was bought new (and a hybrid thing has more than enough juice to spare). Probably more that the various sensors are confusing the brain, which can't decipher the road and other environment conditions to get the safety thing back within normal tolerances.

If it was icy, once the system activated, did the rest of your journey stay cold, so there might well have been something it couldn't cope with?

Thanks for replies, yes I did pull over a few times but it stayed on until end of journey, then next day it had reset. Yes the rest of the journey was cold.

Normally turning off & restarting will reset the system.
