Hi everybody.
I'm new on this forum and have question regarding OBD11 codes.
1) is 2000 GMC Sierra Truck using these codes ?
2) where can I find lising of all codes ?
Thank you very much,
januszon

1) Yes I believe your 2000 is OBDII compliant
2) You can find codes in a service manual available at most auto parts stores, like a Haynes or Chiltons manual.

Hope this helps.

If your truck is throwing a code you can get it read at Autozone and they will tell you what it means and what your truck needs to correct it.

ALL 96 and later cars and light trucks MANUFACTURED for sale in US market are OBDII compliant/equipped. Newer connection standard starting to come through on some vehicles is OBDII CAN which will be mandated by 2008. See http://www.gendan.co.uk/articles.php?article=9
