Tools are something that ALWAYS pay for themselves.
If you fix something once, you have wisely spent your money. Lend it to a friend, , he'll owe you one.

(Don't tell me it's a paper clip!) According to the service manual for the '96 - '00 Civic (pages 11-7 and 11-81), the old MIL blink routine can be used instead of a scan tool. Again, according to the manual, there is the regular OBD2 Data Link Connector under the steering wheel, and there is a Service Check Connector tucked away by the ECU (right side of passenger foot well). The Service Check Connector has two pins only, and you short them with a paper clip then turn on the ignition. On the service check connector, one wire is ground, the other is an input to the ECU. This latter wire is NOT duplicated on the OBD2 connector (although the wiring diagrams for that section are very poorly scanned in my manual, there could easily be lines missing). VW Golf and Jetta from around 1990 had a great setup: The check engine light was in a push button on the dash. To read the codes, you just pushed the button and read the flashes. |

I have a US 1997 Civic LX sedan owned since new.
Jumpered the connector in my pass. footwell and read CEL 2x with success. Once for loose gascap (it was actually tight, but was a cheesy aftermarket one which i tossed) and once for failed O2 sensor. Correct both times. Not sure but Civic might have changed in 1998. Jeff |

so which table did you use to interpret the flashes? In the shop manual?
