98 STS Security light, traction , abs light

[94sportsedan]

I was looking at buying a 1998 STS. The person told me they just replaced the climatecontrol unit. I guess they had the battery disconnected. But now on start up the security, abs and traction control lights all light up and stay on. The person selling the car informed these were no on before he replaced the climate control. Is there some sort of reset?

the traction and abs light to me would indicate a problem with the breaks or what not. I couldnt tell you about the security light though.
