QX56 Service Engine Soon, PLEASE HELP!

[sijia10358]

Hey guys I have a 2005 QX56 with about 56,000 miles. Recently the service engine light came on, I was wondering if its the same as CHECK ENGINE LIGHT. Also what kind of maintenance do I need to do to get rid of the light. Is there a list of maintenance that can guide me to fix the car?

Thanx guys!

Could be many different things, one thing simple is to make sure your gas cap is tight, if it isn't, that will cause the SES light to come on.

You will have to have somebody hook up a scanner and pull codes. There are some places that do it free. If you go to a parts store and get the codes don't let them sell you anything until you diagnose the problem first. Tell me the codes and we can get started.

hey guys, i went to check today and it came out to be TCS communication fail and #1000 communication or something like that.

my tire pressure light came on a while back (dont know if its that) and also the windshield wiper water light came on a few month ago

The U1000 is a communications code. the TCS is a traction control system code. A failure on the communication line has occurred. I would clear codes and see if it resets. All of the modules talk to each other on the hi speed can line. If a module cannot communicate for some reason it will set a code. Communication codes can be very difficult to properly diagnose. If the code resets it may have some type of failure with the traction control system. I would take to a qualified shop that deals with driveability problems.

before I left the shop we reset the light. Ive tested the car, it seems like every traction function is working (abs,tractioin).
