VIN / Build Split
VIN pos 4-8 identifies model/engine/restraint. Ram WMI: 1C6, 3C6 (Ram truck). Position 4-5 = model. Position 10 = model year code.
Use vehicle lookup when you know the year, make, and model. Use quote when the car is in front of you and the symptom matters more than the catalog page.

Common RAM Trx issues we resolve on this platform: Rear View Camera, Forward Camera (Monocular), ParkSense Front/Rear Ultrasonic Sensors, and Bilstein BlackHawk e2 / Fox Live Valve Adaptive Shock System recalibration after windshield/bumper/suspension/CCM service. Module programming for replacement ECU/PCM, BCM, TCU, or accessory modules - DT (Ram 1500 DT - TRX Hellcat variant, 2021 Launch Edition + Standard) platform uses CAN-C (500 kbps HS-CAN) + CAN-IHS + private CAN (Bilstein/Fox adaptive shock controller); SGW active - wiTECH 2.0 bypass required. Key programming and immobilizer faults - Chrysler RFHUB / FOBIK (rolling code, 315 MHz + 433 MHz) immobilizer; all-keys-lost supported. Stellantis Secure Gateway (SGW) module faults requiring OEM subscription access for full read/write (handled on our side).

ADAS calibration pricing for a 2021 RAM Trx depends on which of its 4 documented systems need work after a repair. This vehicle is documented with Rear View Camera, Forward Camera (Monocular), ParkSense Front/Rear Ultrasonic Sensors, and Bilstein BlackHawk e2 / Fox Live Valve Adaptive Shock System. We provide a fixed quote after confirming the operations performed - send the VIN, the repair scope (windshield R&R, bumper work, alignment, collision), and any DTCs and we return a number within 4 hours.
Yes. The 2021 RAM Trx uses a factory SRS control module that we support. We read and clear stored crash data, then restore the module to factory status so the airbag warning light goes out and the system returns to full operation. Bench-only or in-vehicle - both paths are supported. Send the part number and a description of what triggered the light, and we will provide a quote and ETA.
After windshield replacement on a 2021 RAM Trx, Rear View Camera and Forward Camera (Monocular) rely on the forward-facing camera and require recalibration before the systems return to operation. We perform the calibration on-site (DFW Metroplex) with OE target fixtures or via mail-in for the front camera/radar module.
Most 2021 RAM Trx jobs complete same-day once the vehicle or module arrives. This vehicle has roughly 14 programmable modules documented in our database (2 ECU, 3 BCM, 1 TCU, 1 ABS, plus IPC/SAS/gateway/accessory). Module-bench work (ECU clones, BCM reprograms, SRS resets) ships back inside 1-3 business days including return shipping. ADAS calibration is on-site for DFW or mail-in for the front module.
Both. We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, key programming, IMMO pairing, post-repair recoding) and a mail-in bench for module-only jobs (ECU cloning, BCM repair, SRS reset, TCU clone). The 2021 RAM Trx uses Stellantis Secure Gateway (SGW) that requires an OEM subscription for full programming - we handle that on our side, no separate sign-up needed. Quote the work and we will tell you which path is right for the 2021 RAM Trx.
Every programming, cloning, and calibration job on the 2021 RAM Trx is backed by a workmanship warranty covering the scope of work we performed: 1-year unlimited on all flashes, clones, and ADAS calibrations. If a module we programmed or a calibration we performed fails to function as expected, return it and we restore it at no charge. The warranty covers our work; it does not cover unrelated mechanical or electrical failure of the module itself.
Yes - all-keys-lost is supported on the 2021 RAM Trx. Immobilizer generation on this platform: Chrysler RFHUB / FOBIK (rolling code, 315 MHz + 433 MHz). Adding a key (with a working key already in hand) is also supported - typically faster and less expensive than an all-keys-lost reset. Submit the VIN and we will confirm the procedure and quote before scheduling.
We program, clone, repair, or replace the full programmable-module stack on a 2021 RAM Trx. For this vehicle our database documents:
Infotainment on this platform: Uconnect 4C. Send the VIN and the operations performed and we will confirm support and pricing.
Send your VIN and we'll confirm exact module support and pricing for your specific vehicle within 4 hours.
