Yes you can, but it depends on your source of how to check, and the engine must not be running,
under the cover infront of the handbreak is the 16 pin arrangment you need, as you look at it from the drivers side take the row of 8 closest to you and counting from the the side closest to the gearstick count 4 put one end in that hole, then count 6 and put the other in there
turn on ignition and wait for it to start flashing, yours shoyld have a 4 digit code 10 flashes = 0 3 flashes = 3 etc etc
hope this helps, however i got the wrong terminals at some point and now my dash, indicators etc don't work, so i need help with that anybody??
