Hey how are you

The flashing 4hi Y traction is telling that there is a Fault in the system, To find that out you need afactory scaner or equivalent to read the necessary module and retrieve fault codes so e can look up the trouble shoot, if this is teh first time ths happened and it was a glitch we can try to Manually reset it ,lets do that & go from there

make sure we have good 12 volt battery first

Master reset Procedure

1- Disconect Battery Cables ( Negative & Positive Cables )you can use any electrical wire as an extension if battery cables don't reach .

2- Hold cables Together for 60 secs ,then let go

3- Wait 15 minutes

4- Make sure all doors are closed

5- Reconnect battery Cables

6- Lock & unlock the vehicles using the key from driver door side (if you have a key fob with no blade key, just lock & unlock using the key fob buttons)

7- Enter the vehicle and attempt to start

Please let me know

Thank You

The center is a joke. My 13 year old could give me this answer. It's a blank answer and not specific to my lights or my problem. Thanks for no help
