When changing tire sizes, you will usually get a wrench icon on your cluster and the P160A DTC. Here’s how you can fix it with FORScan:

Step 1. Change the tire size in your BCM.

Step 2. In the FORScan programming screen, run the top option called "PCM Module Initialization/relearn vehicle data".

Step 3. Afterward, run the option “TCM relearn” in the programming screen. You are done. This should get rid of the wrench icon and the DTC.

Note: If you can’t find the "PCM Module Initialization/relearn vehicle data" option in your programming screen, you are currently using an older version of FORScan. Download and install the latest FORScan version here.  

In order to configure settings with FORScan after changing your tire size, you will need a reliable OBD2 adapter. These are our featured OBD2 adapters that work flawlessly with FORScan. 

Note: For FORScan coding modifications, we recommend using the OBD2 USB adapter for it provides a more stable connection.
