I failed to change my water pump and blew a head gasket at 140k miles. Also my hybrid battery is nearing end of life so I’ll be swapping it out for OEM next week Now I’m watching things more carefully. However I would like to create a custom dashboard for Car Scanner (bat temps, intake manifold, EGR pressure, a few more) and I am not finding a manual anywhere. The FAQ is pretty useless. Also same for Dr Prius although they seem to be more about running the test than a dashboard. any suggestions for app how to?
I have never heard of Car Scanner Pro, but a popular OBD2 app is "Torque" and it has a Pro and Lite version. There is also these custom PIDs you can add as well: GenIII Prius Custom PIDs for Torque app | PriusChat
I don't use Dr. Prius much but I don't think it has a typical dashboard feature. Car Scanner is pretty self explanatory for how to create a custom dashboard (use the setting gear at the top of the screen when you click on a dashboard), the trick is finding the codes for the custom PIDS that aren't included in the default list. If you search for the "Custom PID list for Torque app" and open the .CSV file in a google spreadsheet it will list all the PID codes, headers, and formulas. Then you just select NEW PID in Car Scanner and under Sensor Properties you fill out all that stuff. For example for battery cooling fan speed it would be Command: 219B, Header:7E2, Formula: B, Min:0, Max:6 You can even do an Action PID, which could be useful for things like changing the reverse beep mode, although I haven't tried this with Car Scanner. I did experiment with HV battery fan speed control and it does work, but it only lasts for a second (there's been discussion on why which I won't get into).
Torque is great for Android, but I'd almost rather just use Hybrid Assistant because of it's fabulous dashboard. I tried to get Torque for IOS and I'm pretty sure they are all scams. Make sure if using Car Scanner on IOS it's the one by Stanislav Svistunov.
Is there something that I can download or use to diagnose what's causing the traction control to engage erroneously after the steering rack change. Is there something that would show an incident occurrence while happening? I don't have access to tech stream but have a good connector for my laptop and Android phone. I've been trying a lot of resetting and bearing replacement. Also wheel speed sensor replacements. The weird thing is that when I thought of replacing the traction control yaw unit, it wasn't where it was supposed to be. The location of the unit that I removed from the same year and model from the junk yard wasn't the same location on my car and I don't know where it is. Any ideas?
Torque or Car Scanner can graph wheel speed data which might be helpful. They also both have Freeze Frame options, which as Chapman mentioned in your other thread, might be your best bet for useful data. I've never tried Freeze Frame on an app so I have no idea if it'll work. What do you mean by "good connector?"
Alright, well get Torque and see what happens when you use the Freeze frame option after causing the ABS to activate. I have no idea what will happen, but it's worth a shot. Go to "fault codes" then click the three dots on the top right and there's a Freeze Frame option.
Thanks. I did finally find the yaw traction control module. I'll replace it with another. I also noticed that the steering wheel wasn't quite centered. So I'll move it a spline to the right. I'll try to use the Torque app to check and reset everything. I appreciate your advice.
Do whatever you want, but why not try to get some data that could lead to a correct repair rather than just guess and replace parts, which doesn't seem to be working out so far?
True. But, at 277,000 the car will eventually need replacement parts anyway. I realize that it would be more prudent to go that way, but my plan is to keep the car for as long as I can. Slowly, like the B-52, keep it in service forever.
