FREQUENTLY ASKED QUESTIONS

FAQ

How much does ADAS calibration cost for a 2020 Jeep Grand-Cherokee?

ADAS calibration pricing for a 2020 Jeep Grand-Cherokee depends on which of its 4 documented systems need work after a repair. This vehicle is documented with Forward Collision Warning (FCW) - Forward Camera, Blind Spot Monitor Sensor - Left (BSM), Blind Spot Monitor Sensor - Right (BSM), and ParkSense Ultrasonic Sensors (Front/Rear). 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.

Can you reset the airbag light on a 2020 Jeep Grand-Cherokee?

Yes. The 2020 Jeep Grand-Cherokee 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. Reference part number on this vehicle: 68222 877AA. 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.

What is needed after replacing the windshield on a 2020 Jeep Grand-Cherokee?

After windshield replacement on a 2020 Jeep Grand-Cherokee, Forward Collision Warning (FCW) - Forward Camera 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.

How long does a 2020 Jeep Grand-Cherokee module service take?

Most 2020 Jeep Grand-Cherokee jobs complete same-day once the vehicle or module arrives. This vehicle has roughly 17 programmable modules documented in our database (5 ECU, 2 BCM, 3 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.

Do you cover the 2020 Jeep Grand-Cherokee on-site, or is this mail-in only?

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 2020 Jeep Grand-Cherokee 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 2020 Jeep Grand-Cherokee.

What kind of warranty do you offer on 2020 Jeep Grand-Cherokee programming?

Every programming, cloning, and calibration job on the 2020 Jeep Grand-Cherokee 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.

Can you program a 2020 Jeep Grand-Cherokee with no working keys (all-keys-lost)?

Yes - all-keys-lost is supported on the 2020 Jeep Grand-Cherokee. Immobilizer generation on this platform: Chrysler RFHUB/SKREEM v2 (128-bit rolling code). 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.

Which modules on a 2020 Jeep Grand-Cherokee can you actually service?

We program, clone, repair, or replace the full programmable-module stack on a 2020 Jeep Grand-Cherokee. For this vehicle our database documents:

  • 5 engine control (ECU/PCM)
  • 3 transmission control (TCU/TCM)
  • 2 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
