I have Accord with 5-pin DLC will this also work?
The compatibility with 5pin DLC has not been tested yet, if the ECU is HOBD1 variant it may work just fine. The 5 pin direct plug-in interface version may be released later.
It is 37820-PDE-E03 (1999 UK) so could be OBD2 B but without 16-pin DLC and also its 5pin DLC last pin is empty. Will try 5pin to 16pin adapter first.
I'll look into this matter the next year.
False alarm. It seems if outer 5-pin wire is missing it means it is routed to 16-pin DLC located somewhere. 5th pin is for ECU OBD and 4th pin is for ABS, so most adapters which convert 5-pin to 16-pin ODB2 won't work as connect to ABS only. Traced from ECU A21 (K-line) pin that it is located near console at left side of passenger legs - http://www.ardio.ru/dlclocs/hondaaccord2000lhd.jpg
So the actual connector which has K-line wire is the one on the picture? How does the 5pin DLC looks like anyway?
It looks like this:http://s019.radikal.ru/i641/1209/0d/cf395df892ec.jpghttp://www.hondamotor.ru/albums/album39/5_G.jpghttp://honda-tech.com/forums/attachments/honda-civic-del-sol-1992-2000-1/390610d1425606979-where-data-link-obd-ii-connection-97-civic-data-link-connector.jpgAs you can see OBD2 compliant cars are missing 5th wire which is K-line for ECU diagnostic. So only question would be for cars which have all 5-wires if it is OBD2 but without OBD2 connector or it is Honda OBD protocol.
thanks for the info
A lot of people in the UK run a modified P28 like this: https://h-tune.co.uk/socketed-and-chipped-obd1-p28-vtec-ecu1/
Yep, that's a custom chipped OBD1 solution, which has so many clones. I'll see what can be done about it the next year.
