Programming Procedure
- If using JLR SDD you will need to run:
- “Configure New Modules – Central Junction Box (Body Control Module)” under the Service Tab.
- If using Autologic Diagnostic / Opus Equipment you will need to:
- “Copy From FSJB to RSJB” under the “Vehicle Configuration” Tab
- Program the “Keyless Vehicle Module” (KVM) as an existing module in the “Module Programming and Replacement” tab
- All after-programming routines, including copying the auto configuration from the FSJB, learning chassis number, learning the target identifier (security) and verifying the Keys.
- It is possible that the immobilizer reset function should be performed and finally re-provision the modules.
If you require any assistance, give us call and we should be able to guide you through the process.
