I just got a Scan Gauge II and plugged it into my 2004 RAV4 Inline 4 4X4.

I found the codes for the wide band upstream A/F sensor to be

A/F Ratio (bank1,sensor1)
TXD+686AF10124
RXF+04410524
RXD+2808
MTH+05B900800000


The display typically shows "147" which is the actual air/fuel ratio of 14.7 : 1 (Mass of air to Mass of fuel)

I found the codes for the narrow band downstream O2 sensor to be

(bank1,sensor2)
TXD+686AF10115
RXF+044105150000
RXD+2808
MTH+000100020000

This gives an output that jumps around each side of 50 for lean and rich (normal operation at cruise and idle). It goes more towards 0 when lean (take foot off pedal at cruise) and more towards 99 when rich (acceleration, load). "50" is equivalent to A/F of ~14.7.

Does anyone here have the X-gauge codes for the RAV4 Hybrid? Their website doesn't have them, only for the different Prius generations. I have two Scangauges that were well-used in my Gen 2 Prius, and had it originally programmed for "SOC" (battery state of charge) and "Amps" (traction battery amps). Those two gauges no longer work in the RAV4, so I imagine the programming codes must be different. Thanks!

I figured out the codes for "SOC" (battery state of charge) for the RAV4 Hybrid. As I suspected, it's the same as for the Gen III Prius, except the code given at ScanGauge's website has 1 error in it. Here is the correct code:
TXD: 07E2015B
RXF: 0441855B0000
RXD: 2808 (website says 2308 for Gen III Prius, which doesn't work).
MTH: 03E800FF0000

I programmed my ScanGauge II with these codes, and went for a drive to test it. Went up 1000' hill, then slowly down 1000' to charge the battery to max. It went up to 79.5% before kicking on the engine to stop charging the battery. When I got back home I was at around 60%, then I kept the car on with the A/C running to drain the battery. When it got down to 40% the engine kicked on to charge.

Success!

Now if we could get the codes for battery amps (charge/discharge), that would be terrific! I had it for my old Gen II Prius, but ScanGauge website doesn't publish battery amps coding for any other vehicle.
