Triggers for ADAS recalibration
Windshield Replacement Affected: Forward Camera (LDW/FCW)
Static camera calibration required via wiTECH 2.0. Level surface, target board per wiTECH procedure. SGW active - wiTECH 2.0 mandatory. DTC clear post-calibration.
Shock or Suspension Replacement Affected: Bilstein BlackHawk e2 or Fox Live Valve Shocks, SCM, ABS/ESC off-road mode profiles
Adaptive shock replacement requires SCM initialization and full calibration via wiTECH 2.0. All four corners calibrated as set. Launch Edition Fox shocks: different calibration procedure - confirm variant. ABS/ESC off-road calibration verify post-replacement. Off-road drive mode profiles reset and reload.
PCM Replacement Affected: PCM (SRT Hellcat calibration lock), all PROXI modules
CRITICAL: wiTECH 2.0 + DealerConnect ONLY - SRT calibration lock will brick PCM if non-authorized tool used. TRX PCM not interchangeable with Challenger/Charger Hellcat PCMs. PROXI alignment of all modules required. Battery SOC above 80% before programming.
Front Bumper or Grille Repair Affected: Forward Camera (LDW/FCW), ParkSense front sensors
Forward camera static calibration required after bumper or camera bracket repair. ParkSense sensors: DTC clear and functional verify. SGW active - wiTECH 2.0 required.
Any Collision Affected: ORC, forward camera, all deployed restraints, adaptive shocks
Full module scan via wiTECH mandatory. ORC: replace-only if deployment DTC present. Inspect Bilstein/Fox shock mounts and control lines. All ADAS recalibration after any front or windshield structural repair.
Forward Camera Replacement
Camera module replacement requires full recalibration using wiTECH2.

FREQUENTLY ASKED QUESTIONS
FAQ
How much does ADAS calibration cost for a 2021 RAM Trx?
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 so the quote response can include a real number.
Can you reset the airbag light on a 2021 RAM Trx?
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. Mobile diagnosis and programming are available in DFW, and mail-in module service is available nationwide. Send the part number and a description of what triggered the light, and we will provide a quote and scheduling window.
What is needed after replacing the windshield on a 2021 RAM Trx?
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 in the DFW Metroplex with OE target fixtures. Mail-in module service is available nationwide for eligible module work.
How long does a 2021 RAM Trx module service take?
Most 2021 RAM Trx onsite jobs are typically scheduled within 24-48 hours once vehicle readiness, access, and route timing are confirmed. This vehicle has roughly 14 programmable modules documented in our database (2 ECU, 3 BCM, 1 TCU, 1 ABS, plus IPC/SAS/gateway/accessory). Mobile module work and ADAS calibration are scheduled in the DFW service area after quote review. Mail-in module service is available nationwide.
Do you cover the 2021 RAM Trx on-site, or is this mail-in only?
We run a mobile unit across the DFW Metroplex for on-vehicle work (ADAS calibration, post-repair recoding, and supported module work). Mail-in module service is available nationwide. 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 confirm the active service path for the 2021 RAM Trx. Do not ship a module unless support confirms next steps.
What kind of warranty do you offer on 2021 RAM Trx programming?
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.
Which modules on a 2021 RAM Trx can you actually service?
We program, clone, repair, or replace the full programmable-module stack on a 2021 RAM Trx. For this vehicle our database documents:
- 2 engine control (ECU/PCM)
- 1 transmission control (TCU/TCM)
- 3 body control (BCM and related)
- 1 ABS / brake control (EBCM)
- 1 immobilizer / security
- 1 key & fob
- 2 instrument cluster (IPC)
- 1 steering angle sensor (SAS)
- 4 ADAS module
Infotainment on this platform: Uconnect 4C. Send the VIN and the operations performed and we will confirm support and pricing.
