When using the VXDIAG VCX Nano Toyota diagnostic device, some users have reported an issue: they successfully installed Techstream version 18.00.008 and properly connected the device to their vehicle, but cannot find the 2021 Tacoma (US model) option in the vehicle selection list.
Problem Analysis
Many users who encounter this issue often suspect that their software version doesn't support the model. However, Techstream has actually included the 2021 Tacoma option since version 15.00.026. In most cases, the problem occurs due to incorrect region selection.
Toyota vehicles have different configurations and system settings in different regions. The diagnostic software needs to match the corresponding regional information to correctly display vehicle models sold in that region. For the US version 2021 Tacoma, selecting the wrong region will result in the missing model option.
Solution: Select the Correct Region
The key to solving this problem is choosing the right region. Here are the specific steps:
- Open the Techstream software and navigate to the vehicle model selection interface
- In the region options, be sure to select "America" (note: do not mistakenly select other regions such as Europe or Asia)
- After selecting the region, proceed to choose the vehicle model. You will now find the 2021 Tacoma option
We hope this information helps you resolve the missing model option issue. For more tips on using VXDIAG devices, please stay tuned to our technical blog.
