Being new to the forum and reading many different posts I recognize many of you have code readers to identify faults and interpreting to investigate issues. Are there better code readers, not 'cheap' but inexpensive or is getting a higher price one more important?

Thanks in advance,
Wes

 

OBD scanners span the sprecrtum. Everyone has a preference. Below is the thread discussing the attributes. My preference is Icrarsoft for jaguar/land rover.

Same recommendation here

 

Ensure that the vendor has a favorable return policy in the event you are not satisfied with the unit you decide to purchase....

 

On top of getting a proper Jaguar/Land Rover code reader, be sure to also get a cheap ELM327 and a phone app. So cheap, not worth being without. These are great for data logging of basic parameters while you drive, fuel trims, as well as reading (standard) codes and resetting the CEL. An application like Torque Pro lets you build a custom screen with whatever combination of gauges you need, like all the numbers related to the trims: short/long term and bank 1 or 2, along with load and rpm. Speaking in principle, a cheap ELM327 can read everything from any of the 3 data buses, proprietary Jaguar or not. It is jut that the associated app does not have Jaguar support to interpret the data. In other words, as folks discover the encoding of proprietary Jaguar codes over time, it is technically possible to add them to the app.

Best of luck, keep us posted.

 

Thanks to all of you! I am reviewing the information you provided. Will be interesting to use these tools!

Appreciate it!

I will second this. I have BlueDriver, which is basically a more expensive version of this, but I'm not sure it provides anything more. Being able to read and log live data while you drive is pretty helpful. And, in my case, clued me into a cooling issue that I otherwise might've missed until it was too late.

 

I got a Streetwise OBDII WiFi code reader and it works fine with my XE but will not connect to the ECU on my XKR :-(

I've tried various softwares with the same result. I would like to think it is the code reader but as it works fine on my XE i'm not so sure. It is drawing power from the connector in the XKR as i can connect to it with WiFi but just can't access the ECU. So may be a dodgy pin on the connector... any ideas how i can test this theory?

See if you can "force" the ISO-9141 protocol. The thing is that there are operational CAN and SCP networks, but OBDII is not available there. Only over the older serial ISO-9141.

 

I tried this with Torque and no luck but just downloaded another app called OBDclick and forced ISO-9141, connected straight away! Weird how these apps can have such different implementations of what should be a standard.

 

You can definitely go into the settings in TorquePro and set the protocol to ISO-9141. I do it with my adapter to get a quicker connection.

<gear> -> Vehicle Profile -> <little pencil for edit> -> Preferred OBDII Protocol -> ISI 9141-2

 

Oh yea, you can def do it. It just didn't make any difference for me. Still wouldn't connect.
