Define the operation
- Separate a software update from replacement setup, coding, security pairing and calibration.
- Record the current software, part number, VIN and configuration before changing anything.

PROGRAMMING DECISION GATES
Do not treat every service event as a simple flash. Determine what must be transferred, authorized, calibrated and verified before writing software.
NETWORK & PROGRAMMING ACCESS
These are common implementations, not a vehicle-specific pinout. Confirm the exact topology, protocol and gateway route in current OEM service information before connecting or programming.
Automotive Ethernet, CAN/CAN FD and MOST are common; LIN may serve local controls. USB, LVDS, APIX/GMSL or similar display links are point-to-point media interfaces and should not be diagnosed like CAN.
Large packages commonly use DoIP/Ethernet, USB or OEM media; configuration may still travel over CAN. Gateways can require secure diagnostic authorization and certificate provisioning.
Display, amplifier, telematics, cameras, cluster, USB hubs and gateway routing tables may all be package dependencies. Preserve customer settings and feature entitlements where permitted.
BEFORE CONNECTING
✓ All network branches and termination checked✓ Correct region, option and hardware identifiers✓ Reliable wired network connection for online programming✓ Support supply sized for extended sessions✓ OEM account and security authorization where requiredCOMPLETE TEST SEQUENCE
POST-PROGRAMMING VERIFICATION
Software, subscriptions, security access, voltage targets and ignition sequences vary by manufacturer and model.
