99 Civic Check Engine Light
Hi there,
Got my sister's car with the CEL on, she doesn't maintain it that well... All of the ignition stuff looked wore out, so I replaced Cap, rotor, Wires, and plugs. However, the light came back on. What is the procedure to check for the ECU trouble code if I don't have a scanning tool? Any other ideas other than checking the code that I may have overlooked? t |

RTFSM (Read the ****ing shop manual ) Visit a dealer and read their ****ing shop manual if you don't have a copy. |

HEY ASShole. I have the '****ing' shop
manual, and i read it. It sure tells me how to scan the code if I have an OBDII tool. I don't have one of those, so i am asking the nice people on this forum for some input. So go take a long walk off a short pier, OK? Dumbass. Anybody else with something useful to say? t |

I thought there was a way to jumper the service
connector and watch the CEL flashes to determine the codes being thrown. Am I mistaken? t |

Pin 1 in the diagnostic connector is the SCS line. The blink codes are listed in the book. It says it will blink them out if the SCS line is jumped by the Honda PGM tool. What it doesn't tell is what line it has to be jumped to in order to activate it. |

The 96 and 97 accord (and odyssey too) have the jumper also, I guess to
phase people in for a little while. The service manual should give both procedures for troubleshooting. (with scantool and without). > > Not after 1995, unless someone has information I haven't got. > > For pre-'96, see he > http://www.iequus.com/assets/manuals..._E_14JAN03.pdf > > > > -- > TeGGeR® > > The Unofficial Honda/Acura FAQ > www.tegger.com/hondafaq/ |

The sketch in the FSM looks like a digital multimeter (a screen, a square
keyboard array under the screen and a data cable coming out the bottom). On 2/14/05 7:33 PM, in article , "TeGGer®" > wrote: > "E.

Then it's still not a DIY thing like the old service connector was. > > It might be. There are only 6 wires connected to the 16 pin connector - Pin 1 is the SCS line Pin 6 connects to SRS & ABS/TCS units Pin 8 goes to a fuse Pin 12 is a ground Pin 13 is another ground Pin 15 is the scan tool I/O line & also goes to the MIL through the PCM just need to find out which Pin line 1 needs to be jumped to. It pretty much has to be one of the grounds or the I/O line. I don't plan to try it unless I can figure it out definitively, though. |
