The light you are referring to is the immobilizer light or theft deterrent system light.Also what you are describing is normal operation.

Can you remove the ECU-B fuse and see if it still happens? That fuse is a 15a fuse in the junction block on the drivers side end of the dash. With that fused removed, tell me if this continues to happen. Thank you.

I don't know what the ECU-B fuse does but it seem to have corrected the problem.

ECU-B is a circuit that controls multiple Items, but one of them is the radio and blower motor and all that. Glad I was able to help and it seems to be a straight forward fix! Please do not forget to rate me and my service! Thank you!
