OBD2 PIDs

[Farnham Dave]

I've bought a Bluetooth OBD dongle, and installed the Torque app on my android phone.

Other than the immediate benefits, such as checking for fault codes (I have none!), I also hope to decode the PID information provided by the interface so I can check on hybrid Battery health and so on.

I'm having trouble finding a list of the codes for the RX400h. I have a spreadsheet I downloaded from PriusChat (which was the result of a long topic on there regarding the RX400h), but some of the values being displayed on the Torque app don't make a lot of sense, eg: Battery voltage -2800v.

Has anyone got access to this information?

My suggestion is to search on google DTC on Toyota / Lexus   😉

It's not the DTC (Diagnostic Trouble Codes) I need, but the PID information. For example, PID 21C3, header 7E2 includes things like "MG1 inverter temperature" using the equation "U-50".

While I'm not that bothered by the MG1 inverter temperature (at the moment), these codes can also provide information about the state of the hybrid Battery and other components of the car.

You say the Battery voltage does not make sense at 280 volts, but that is correct for the RX400H.

Yes, 280v would make sense, but I said -2800v.

About PIDs, you can find something on Prius forum.

I've never looked for PIDs but I'm sure Techstream would display whatever it is you're looking for.

Ok, I'll let you know how I get on.

I didn't find any more information, but did manage to get it working!

 One of the main reasons I wanted to access data from the OBD is to do a check on the Battery. If I understand correctly, a "sick" Battery is one where one or more blocks are measurably weaker than the others. I think this screenshot shows that is alright.

I know it's only a snapshot... When hybrid Battery was quite low on charge, but I'm going to monitor it occasionally just to see how it is at different states of charge.

I took a look at Torque on my car but couldn't find anything useful.

After more searching i took the plunge with the 'Hybrid Assistant' app and a quicker OBD dongle. It's loaded with features and well worth a try.

Which dongle did you buy?

[Farqui]

One of these, not cheap but they're much quicker than the cheaper devices

I got one of these...

Hi,

I have a 2006 RX400h in USA and am also trying to figure out the best app to use.

I found RX400h and install instructions here

Good luck
