how do you reset via the diagnostic port? cheers

dont think u actually can without a diagnostic comp thingy (i know even tho haynes says u can) just unplug the battery leave for bout 2 mins then put it back on i know more hassle but it works...

More than two mins, leave it overnight if you can. Takes at least 40 mins...

Reseting via diagnostic port, i think only lets you reset the ecu's found fault codes.

(Using the haynes paperclip diagnostic method anyway)

just the fault codes ie if a dash light is on but if its a genuine problem the light is gonna pop back on sooner or later

thankyou!!!!
i remember reading that thread "micra pete" lol.
with the new battery fitted the car doesnt seem any different which is good, but just wasnt sure if the ECU reset did anything else.
cheers
