my check engine light came on and i tired to check it to see what it was. i found on a different forum to jump #4 and #9 on the OBDII connector pinout and turn the engine to ON. and count the flashes. well stupid me jumped #4 and #16 because it was upside down and the 6 looked like a 9, so after i did that it sparked for a sec. then i connected it correctly and tried to pull the code again, but the check engine didnt light up anymore. so i tried to start the car and it would crank but not turn over. no check engine light at all, normally it would turn on and go off but nothing at all now. is this information correct?

pin 4 = chassis ground
pin 5 = signal ground from ECU pin E3
pin 7 = K-line (2-way OBDII comms line) to ECU pin E23
pin 9 = SCS line to ECU pin E29
pin 12 = write-enable signal to ECU pin E30
pin 14 = +5 V
pin 16 = +12 V battery voltage

what should i be checking for? btw i have a 2000 accord lx

Looks like you jumpered directly from battery to ground, so look for blown fuses. Maybe that pin 16 shares a fuse with the ECU power? On a 6th-gen Accord I think you have 3 fuseboxes to check - under hood & both ends of the dashboard.

 

thanks for the quick reply...from what i read there is no fuse in between the obd connector and the ECU. so with that being said i hope i didnt fry the ECU. here is a direct quote

" There are actually 3 or 4 variants of the OBDII "standard" but Honda uses ISO 9141. The reason you want to be a bit careful when probing the OBDII connector is that the pins run directly to the ECU (no fuse in between), and like you said, there are different voltages and grounds in there."

 

anybody else care to give their $.02 on this matter?

 

Check fuse 46 in the underhood fuse box. Pin 16 gets power from there.

 

BINGO that was what it was. my car runs like a champ now. thanks for the help matt
