I set about replacing a couple parts on my cabriolet that I bought from a fellow list member a few weeks ago--a dash surround and headlight. Since I was working on the Cabriolet anyway, I decided to finally try out my theory of being able to somehow blink out and clear codes in the airbag system. I could do it with my Corrado's ABS system, and figured that there was probably a similar system in the airbag system.
My lights had been on since last fall when I mistakenly started the car with the instrument cluster out. (I think I had to move it around while installing the cruise control system or something.) I was quite sure the system logged a code or two due to the lights not being plugged in.
I looked up the how-to for doing this on the Corrado, and when messing around with it, I knew I had made the airbag light blink, but wasn't sure what I had done exactly and couldn't repeat it.
Did some googling and found that the Cabby Info page had been updated since I last looked there for airbag info.
Blinking the codes out worked just about like what was described on the page, with a couple things to add.
First, both codes were four digits. You see one long blink, then a pause, then each of the four digits are blinked as described. (blink blink blink *pause* blink blink blink blink *pause* blink blink etc)
It will repeat perpetually following the same pattern. As soon as the long blink comes again, you can move to the next code. Simply reconnect the jumper to ground for a couple seconds, and then disconnect it. The next code will blink like the first.
Eventually you will see a pattern like this:
long Blink *pause* blink blink blink *pause* long blink *pause* blink blink blink repeatedly.
This means you are at the end of the codes.
To clear the codes, I reconnected the ground and disconnected a couple more times and each time got the final pattern of long blink *pause* blink blink blink.
Once I completed this, the lights were off! I started and stopped the car several times, and the left light came on and went off after a few seconds, just like is used to do!
