Warning lights ON following flat battery

Technical Area Electrics & ICE
1

Following a nasty accident (cycling not driving) and a long period in hospital I discovered that garage procedures were not fully appreciated by co-pilot/Sat-Nav/nurse/wife and my battery trickle charger had been unplugged in favour of some spurious garden implement resulting in a dead flat battery. After reinstating normal services and a long lay off I dared to try the ignition today and while it started first time and idled happily the TCS/DSC and the DSC OFF yellow warning lights both stayed on. I’m sure I’ve read something about this earlier but as am still technically off the road until after Easter [then DVLA permitting] I can’t risk taking it out for an Italian Tune-Up so all comments or suggestions much appreciated

They should clear when you turn the steering lock to lock (engine running) turn off then start again, hopefully no warning lights on​:+1:

By “lock to lock” you specifically need to do:

NOTE
If the battery is disconnected or a fuse is replaced, the DSC will be inoperable. In this case, the DSC OFF indicator light flashes and the TCS/DSC indicator light illuminates.
To make the DSC operable, do the following procedure with the battery connected.

  1. Turn the ignition switch to the ON position.
  2. Turn the steering clockwise fully, then turn it counterclockwise fully.
  3. Make sure the DSC OFF indicator goes off.
  4. Turn the ignition switch to the OFF position, then turn it to the ON position again.
  5. Make sure the TCS/DSC indicator light goes off.

If the TCS/DSC indicator light and the DSC OFF indicator light remain illuminated even after turning the ignition switch to the ON position, consult an Authorized Mazda Dealer.

Thank you very much for that Ian and please may I simply confirm that when you say #1 Turn the ignition ON you mean actually start the engine so power steering is operable rather than simply turn on the ignition. Either way it’s too wet and mizz to get car out of the garage today so I’ll await your reply

best wishes, John

I honestly can’t remember from memory what I did when I had my NC (now have NDs) but technically there are 4 states for your key:

  • Off
  • Accessory
  • On
  • Start/crank

So based on that, no you don’t start the engine
