I just did a reset of the ECU and now my check engine light is flashing when I do the blink test is this normal? as I previously did a test and had error code 22 this is no longer there just the flashing.
Steady flashing?
if so i think thats saying that the reset worked.
Have you disconnected the plugs after doing this?
The ones you connected to get the codes that is, not spark plugs
disconnected then when I got back from the drive. Then reconnected the black plugs to do blink test to see if it erased codes and check engine flashed steadily is this ok
