H27A ECU (hitashi?) - Suzuki XL7 2003 (updated dash ADM market)

Hi All,

What a nice, welcomed write up it was to find this - http://www.rhinopower.org/diag/diag_main.html

I have scoured so many forums from 7+ years ago about ECU scanners for my suzuki, all of the just stop with someone having some success but never really revealing the details.

Long story short: i'm in the middle of building a small 'overlander' out of a cheap 2003 suzuki XL7 i picked up that was in good nick. I would absolutely love to know how i can a) get my hands on a scanner for codes that wont cost the same amount i bought the car for, would alos love to get live data out of the thing too. 

its got what looks like an ODB2 port but i believe the ecu is still on OBD1 using a the KWP2000 protocol? going off the timelines of the write up and my car being a 2003. But still not sure.


Can anyone point me in the right direction and/or what information do i need to give in order to figure out what protocol its using?

I'm ok with tech/IT etc but this is my first ever ECU deep dive, so apologies for the eyerolls!

Appreciate any support or feedback.

Thank you so much for reading
