How to Install a TRD Pro Grille on a 2018+ Tacoma with TSS-P Radar
Swapping your stock Tacoma grille for the aggressive TRD Pro version is a mandatory visual upgrade, but the factory TSS-P radar system complicates the swap. Doing this right ensures you get the exact front-end aesthetic you want without compromising Toyota's safety systems.
The Short Answer (TL;DR)
You can successfully install a 2016+ TRD Pro Grille (PT228-35170) on a 2018 Toyota Tacoma equipped with TSS-P without triggering dash codes. This 1-hour swap requires relocating the sensor to the lower section of the grille and adding the OEM glass garnish (53141-35060). Upgrading your intake while the grille is off is highly recommended.
The DIY Process Overview
Toyota introduced the Toyota Safety Sense-P (TSS-P) module standard on 2018+ Tacomas. This autonomous braking and adaptive cruise radar sits directly behind the Toyota emblem on stock grilles. When swapping to an OEM 2016-2017 TRD Pro Grille (PT228-35170) or the newer 2018 version (PT228-35180), you must account for this sensor.
Contrary to popular belief, you do not need the more expensive 2018-specific grille to retain your radar. The 2016-2017 TRD Pro grille already has the lower mounting location built into the molding. You will need to carefully unbolt the TSS-P sensor from your factory grille assembly and re-mount it to the lower section of the Pro grille.
Once mounted, simply install the OEM glass garnish lens (53141-35060) to protect the sensor. This specialized garnish maintains proper radar calibration so your cruise control and pre-collision systems function flawlessly.
Why You Should Upgrade While You're In There
Pulling the front grille assembly gives you wide-open access to the front of the engine bay. Since you already have the front end disassembled, this is the absolute best time to toss out the restrictive factory airbox and install a high-flow cold air intake. Improving the breathing capability of your 3.5L V6 drastically enhances throttle response.

Frequently Asked Questions
Will this modification throw a TSS-P error code on my dashboard?
If you use the OEM glass garnish and securely mount the sensor in the correct orientation, the radar will calibrate perfectly. Avoid using cheap aftermarket garnishes, as the plastic density often distorts the radar frequency and triggers warning lights.
Do I need any special tools to swap the grille and relocate the radar?
No. You only need a basic 10mm socket, a flathead screwdriver to pop the plastic retaining clips, and a Phillips screwdriver for the sensor screws. The entire process takes under an hour in the driveway.
