Re: ABS light
You shouldn't have a code 4 like that.
Maybe you aren't reading the flashes correctly.
With the SCS diag connector jumpered, turn the key to ON (engine not running).
ABS light comes on for one second and goes out for 2 seconds, then starts flashing codes.
Flashes, then a one second pause, then more flashes = 2 digit code. First set of flashes is the first digit, second set after the ONE second pause is the second digit.
5 second pause. A 5 second pause separates individual codes.
Next code flash sequence starts.
Up to 3 different codes can be stored in memory.
I don't see a code 4 by itself.
The only single digit code in my chart is #1.
All the rest are 2 digit codes.
Try again?
