OBD2 Scanner for 2003 H1

I have a couple of different obd2 scanners (autel al619 & actron) and for some reason neither of them recognize my vehicle? Any ideas. Thanks in advance

The obd2 data link conector is generaly powered by the cigar lighter fuse. Check ALL the fuses. The tt4 light is for the abs. Is the no comunication a new issue?

I've had the ASB/TT4 light stay one and found that one of my ABS sensors was either not close enough to the tone ring, or I had a bad connection with my ABS sensor and just needed to replug it in.

If that doesn't work you may need to do the blink code with the Diagnostic Link Connector (DLC). You can google that to find out how it works.

I bought a wireless scan tool but it only gave me 4 gauges. I think some of the newer scan tools don't work with the H1. I got a ScanGaugeII after a lot of H1 owners liked it and it works for me. I keep it plugged in all the time since it gives me MPG.
