Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive the VIN, as the programming is a required step.
Is this part difficult to install?
The TCCM is typically located on the driver’s side, under the dashboard to the left of the steering column. For most DIYers with basic tools, it is a straightforward installation that involves unplugging the electrical connectors, unbolting the old module, and installing the new one. Since our module is pre-programmed, no special electronic tools are needed.
Will this fix the “Service 4WD” light on my dashboard?
In the vast majority of cases where the TCCM is the faulty component, yes, this part will resolve the issue and turn off the warning light after installation. However, we always recommend a proper diagnosis to confirm the TCCM is the source of the problem, as other issues (like a faulty encoder motor or selector switch) can sometimes cause similar symptoms.
