I have a 2001 xc with 110K. I took it to the dealer due to the ck eng lite coming on. Dealer said an o2 sensor was causing the prob. I replaced the front o2 sensor then disconnected the battery for 2 minutes. Now the heater controls, front seat heat and shift indicator light are not working..50 miles later the eng lite is on again..please help, Rich.

 

You might have to rest the computers lock and unlock with the key and remote.
Also unhooking the battery WILL NOT CLEAR THE CODES IN THE COMPUTER.

 

I'm not sure how to lock and unlock. could you please explain...thanks, Rich

 

Lock the door with the key like if you were leaving the car somewhere. Do it with the remote as well.

 

i tried locking the door with the key then again with the fob. i'm not sure what you mean..exactly what am i to do..thanks again...Rich

 

all the problems inside the car came after i replaced the o2 sensor and disconnected the battery..i'm not sure of the sequence of using the key, then key fob to reset the computer..Rich

 

Tech, I moved this from New Members Area. I was not sure if the car was XC70 or XC90.
