Question about 2004 Chevrolet Tahoe
I have a 2004 tahoe, runs fine but check engine light came on, and when I hook up to pull codes no scanner will communcate with the truck.....Ive tryed snap-on,auto xray,mac,and the cheapy at auto zone. all say to check the connection or turn ing switch on? ive chased the 4 wires all the way to the firewall then I loose them in the harness, the connector is good.... and I cant find a schematic for the truck anywere. Im a heavy equipment mech and have tryed all I can including pulled the computer and cleaned all connections,checked and cleaned all fuses and harnesses under fuse panels,found no problems.even ran the wiggle test on my auto xray 6000 manualy and shook every dahm wire under the dash and hood? im stumped any help would be great. thanks
HI there....Check to see if the code reader is a CAN OBD 2 code reader. If it is only OBD2 , that may be the problem. In 2003 Some vehicle manufacturers ( ford,Gm,Mazda and Saab) began using a new computer protocol called Controller Area Network (CAN) with the OBD2 and if your vehicle is CAN OBD 2 the simple OBD2 code reader will not work.Contact your local dealer to determine if you vehicle is CAN or not or find a code reader that is CAN OBD2 capable. Hope this helps you out
