Can anyone recommend a good OBDII scanner for an 04 rx8? I am trying to diagnose a P2096 CEL and I am working through the flow chart in the service manual. One step is to access the "O2S12 PID". Will all scanners be able to access proprietary PIDs? Thanks!

Here's what I've got for mode 1:

I've got Wideband around here somewhere... can't find it ATM moment though.

And here are the Mode 22 ones I've found:

Code:

obd.getHs().getEBT().sendATCommand2("ATSH000751");
					
final String tpmsPresBuf = obd.getHs().getEBT().sendOBDCommand("22C9011");
final String tpmsTempBuf = obd.getHs().getEBT().sendOBDCommand("22C9021");

final String[] tpmsPres = tpmsPresBuf.split(" ");
							
final float tpmsPres4 = Integer.parseInt(tpmsPres[tpmsPres.length - 2], 16) * 1.373f * KPI_TO_PSI_MULTIPLIER;
final float tpmsPres3 = Integer.parseInt(tpmsPres[tpmsPres.length - 3], 16) * 1.373f * KPI_TO_PSI_MULTIPLIER;
final float tpmsPres2 = Integer.parseInt(tpmsPres[tpmsPres.length - 4], 16) * 1.373f * KPI_TO_PSI_MULTIPLIER;
final float tpmsPres1 = Integer.parseInt(tpmsPres[tpmsPres.length - 5], 16) * 1.373f * KPI_TO_PSI_MULTIPLIER;

final String[] tpmsTemp = tpmsTempBuf.split(" ");
							
final float tpmsTemp4 = (float) (1.8 * (Integer.parseInt(tpmsTemp[tpmsTemp.length - 2], 16) - 55) + 32);
final float tpmsTemp3 = (float) (1.8 * (Integer.parseInt(tpmsTemp[tpmsTemp.length - 3], 16) - 55) + 32);
final float tpmsTemp2 = (float) (1.8 * (Integer.parseInt(tpmsTemp[tpmsTemp.length - 4], 16) - 55) + 32);
final float tpmsTemp1 = (float) (1.8 * (Integer.parseInt(tpmsTemp[tpmsTemp.length - 5], 16) - 55) + 32);

And for the record, my cheapo chinese BT adapter accesses those mode 22 PIDs just fine
