Thanks all for posting this thread, just a clarification why i used a 1500 ohm resistor, 3 reasons;
1 it is safe to use and will not damage anything if the wrong pins are connected together.
2 it fits very well in the contacts of the connector without spreading them open.
3 It's shape makes it easy to remove and insert into the connector within the time limit of the operation.
And i had a good supply of these resistors, the same effect has always delivered by the using a wire link, some use a switch in a purpose made connector so there can not be a mistake made with the different wires and make removing the link in the process simple, just a matter of choice, it all works if done correctly.
As usual Popgun is correct, the ecu has a "pullup" resistor on one of the cpu pins which if pulled low under certain conditions ( this procedure ) triggers the cel indicator to read out the stored code ( s ).
As i understand it if the cel indicator is on solid it indicates a current fault condition, if it blinks continuously it means a major fault is present and if there is no indication the faults have cleared but are stored in ecu memory for diagnostic purposes so they can be read by the service tech and give him some direction if he is servicing the bike.
