I did an ECU diagnostic on my R32 to check for fault codes. I got a 55 so alls good.

Then I turned the screwdriver the other way to turn off the diagnostic mode and the led went out. When I drove the car I found the cat temp light started flashing and so was the ecu led. I assume the ecu is in the oxygen sensor mode.

I turned the screw one way then the other and the lights stopped. I drove the car yesterday and gave it a quick squirt and the lights started flashing again.

What do I have to do to get it out of diagnostic mode?
