OBD-II error codes
Hi,
I am trying to extract error codes (DTC) from the OBD-II without using a scan tool from my 98 accord (125k miles) by making the Check Engine Light (aka MIL) to spit out the codes by short/long blinks. Looks like I need to jumper some pins on the DLC connector so that the codes are redirected to the dashboard. Can someone tell me which pins I need to jumper? I came across someone suggesting we should jump pin #8 to #13, but the DLC pin description says that these pins are un-used (hence my dilemma). Also, does anyone have software that interprets the ISO-9141 data coming out of the OBD-II (I can make the connector wire myself)? Thanks, - A.J. |

Go to Autozone and use their OBD-II reader - they do this for free -
the flashing lights only give you a hint - their reader will tell you exactly nature of the problem. Don't buy repair parts from them till you check on line - frequently genuine honda parts are cheaper on line than autozone aftermarket parts. |

Use the jumper provided. Look at page three of the PDI sheets for a Gen 1 CR-V http://www.tegger.com/hondafaq/tsb/crv/index.html It's similar to what you're needing. You could sign in and SEARCH at hondasuv.com, or just use google.com to find the same procedure for Accord (same as Odyssey too, I think). odyclub.com might have it in the SEARCH. blink codes Accord might be good key words to search on google..

I never did find the magic blue connector on my '00 Accord. |

You > can't have a "consensus" on issues for which verifiable and > repeatable facts exist. > ---snippy--- Apparently, you have never been to where I live http://www.silvertoncolorado.com "Silverton is a town that has its own color and character." That means that practically everyone who lives here, is crazy. Their favorite saying is, "The laws operate differently here". The postmaster, a federal employee, told me this. You could tell them that "The sky is blue" and if the Great and Powerful Town Trustees didn't agree, then it wouldn't be true. Have you ever been to a town meeting? You give them a "verifiable and repeatable fact" that contradicts "common knowledge" and they just ignore you or tell you that you are wrong. Never underestimate the depths of which human ignorance is capable. The Internet, well that is even worse. Why am I here? I like the scenery. Earle |

OBD-II error codes
Thanks to all for your adivce. The Autozone trick worked really well
(they did it for free), I wasn't aware of this service, it is terrific. The DTC code was P0420: Catalyst System Efficiency Below Threshold (Bank 1) which most mechanics interpret as busted O2 sensor. However, bad catalytic converter or retarded spark (timing belt) can also cause this DTC. In my case, it was the last one, so when I had the timing belt changed, the light went away after 50 miles or so of driving.
