89 ka24e CEL Diagnostic

[youkairyu32]

Hey guys bought an 89 ka24e that is throwing a check engine light. I turned the screw on the ecu to diagnostic, but I am getting a weird series of flashes that I just don't understand.

Both red and green bulbs flash together every time.

The sequence is:

1 x long flash
pause
2 x long flash
pause
3 x short flash
pause
4 x short flash
pause
5 x short flash

Any idea how to read this?

Figured it out. Just thought I would update in case someone else has this problem.

One long flash is the startup sequence.

Then it's code 23 (two long flashes and three short flashes)

and then 4 short flashes 5 short flashes is a california only code they added as a bandaid to make it sellable in the state. It is code 45. The lack of a long flash before the short flash was confusing me.

Cheers.
