Hey guys new to Nissan bought an 04 quest ,125k mikes. Upon driving home after purchase realized that tcs abs and o/d button do not work but there is no indication of a fault, like no lights on dash saying theres a problem. Van works great except for those issues. Just wondering if any of that was common or if it's something simple I should look for. Also noticed in the maintenance button that one tire says ** and scrolls flat tire, obviously the sensor but does that have any effect on the other systems?
Thanks
Michael

Not sure that the TCS and ABS would be affected by the TPMS. The O/D button definitely wouldn't though. Usually that is just a button that tells the TCU to keep the car from shifting into O/D. I wonder if the TCU is on its way out? Those are all systems that require input from that.

Can you get your hands on a code reader? Not all problems are going to pop a CEL. Less than half will, actually.

I checked the codes and nothing came up at all. I do think that the abs light might be on but not centered well in the dash cause I do have a bit of yellow light making its way around that area.
