This Grade A chassis brain box is an OEM transfer case control module pulled from a low-mileage 2020 Toyota Tacoma with only 21,223 miles.

This genuine Toyota part is currently on our shelf and ready for immediate shipment.
The chassis brain box serves as the electronic control module for your Tacoma’s transfer case system, managing the engagement and operation of 4WD modes. These modules commonly require replacement due to internal circuit failures, water damage from off-road use, or electrical issues that prevent proper 4WD engagement. When this component fails, drivers typically experience inability to shift into 4WD, dashboard warning lights, or erratic transfer case behavior.

Common symptoms include inability to engage 4WD, transfer case warning lights on the dashboard, grinding noises during 4WD engagement, or the system getting stuck in one mode. Electronic diagnostic codes related to transfer case operation also indicate potential brain box issues.
This module fits 2020 Toyota Tacomas with the specific OEM part number 89533-04070. Different trim levels and transmission types may use different control modules, so verification of your current part number is essential for proper fitment.
Most Toyota transfer case control modules require dealer-level programming or initialization procedures after installation. We recommend having the module installed and programmed by a qualified Toyota technician to ensure proper system operation.
Common failure causes include water intrusion from off-road driving, electrical surges, internal circuit board degradation over time, and corrosion from exposure to moisture or road salt. The 2020 model year typically has fewer age-related failures compared to older units.
While the physical installation involves removing the old module and connecting the new one, the unit requires dealer-level programming and calibration afterward. Most DIY installers can handle the mechanical aspects but will need professional programming services to complete the repair.

RatingAwesome experience Ray was the driver picked up my junk vehicle quickly efficiently and they even called to pick it up before schedule day because they had an opening. They kept their word super happy. I will definitely be using them again in the future.
Great yard ! Parts aren’t damaged and it is the cleanest yard I’ve ever seen! The staff is pretty amazing too !!
good lead times and customer service, look forward to more business here
I'm replacing damaged panels on my 2006 Ridgeline on a tight budget so I may quickly sell it and they were so helpful and priced better than anyone else in the area. Raised a glass of scotch for these ladies! Thanks again!
Great service! The best price and condition for the Porsche Cayenne parts needed to finish the job. Radiator core support and headlight fit perfectly!
Drove from new york, Julie was a sweetheart asked questions to make sure that my ECU was the proper part number and was compatible with my manual Accord, price was phenomenal I highly recommend them for any parts your car may need. Definitely the best salvage yard around
Great experience at 603 Auto Salvage! ⭐️ The owner and employee were both extremely helpful and easy to work with. I was able to find everything I needed in one stop — about seven different items — which saved me a lot of time and hassle. Good selection, fair pricing, and friendly service. Definitely recommend checking them out if you're looking for parts. I’ll be back again! 👍🔧🚗

The customer service at 603 was great. They found the part I needed very quickly and promptly notified me when it was ready to be picked up. There wasn’t any other place in the area that had what I needed. The price was very good also. I will be using them again for sure.
I had a great experience. They didn’t just look up the part I needed they took the time to explain how to install it and made sure I understood everything. I even received a call back, which I really appreciated. Everyone I spoke with was friendly and patient, and I never felt brushed off. I truly felt taken care of. Highly recommend if you want knowledgeable people who actually care about helping you. Kristy Thanks Guys!
Drove from Connecticut to get here. Had parts for a relatively rare car that dozens of other places didn't have. I got a hood, fender and bumper cover that were in near mint condition for a fifteen year old car. They pulled all the parts for me and had everything ready within an hour. Very reasonably priced. Highly recommend
Exceptional service, large selection of parts, will come back if more Audi parts are needed. A++
