Hello,

Just went into the garage to do this coding...

Bizzare stuff...

Okay, here is what I did...

1) ENGINE OFF, turn key to position 2
2) Left setting on HIGH
3) Right setting on LOW
4) Key to position 0
5) Press and hold REST, turn key to postion 2
6) P1 value showed up, but the entire lcd display was flicking, I mean the insturment cluster lcd was fine, the the ac units was flickering, like all the line were partially lit. It was really hard to tell which numbers were showing on the right.

But, I think I got P1 as 120 to begin with, I am lost about the powers thing, do you mean to see if 120 is a power of 2?
2, 4, 8, 16, 32, 64, 128, 256....... 120 is not, but is divisible by 2 but not 16.... please explain...

I upped the value by pushing the right red arrow 16 times.

7) Hold down rest, switch off ignition.

Then I turned back to 2 and turned the ac on, all was normal, EC light is gone, but it is 12:30 now, I did not want to start engine to test. I left a note to my mom not to try and use the ac despite the now unlit EC light, just incase I did not do something right...

Also,
I tried the test where you hold the 2 auto buttons for 10 second, i did this while the car was in ignition position 2, but the fans that are supposed to come on did not... please advise....

Thanks for bearing with me...
