Hi Every one.

I have a 2003 WRX STI💥. 

I am trying to get my car roadworthy, but the darn AB light is on.

Been to 3 companies, they cannot connect to AB computer.

I have check under drivers seat for bad connection.

I have taken box out to inspect for water damage.

 

All seems fine.

 

I am now thinking the I should try to follow the communication line to the Diagnostic reader socket?

I would like to follow the K line to the socket to see if any issues.

Or I would like to run a wire directly from the box to the connection point for the scanner.

Not sure what pin = the Communication line for Diagnostic reader.

 

Any advice or diagrams for me to follow the Kline would be such a help?

Any one experienced similar issues ?
