JLR SDD v142 and Ford IDS v100 can work no issues in one VCM2 china clone, if you pay attention to the synchronization of sw and fw.
That is, the software of Ford and JLR (Jaguar & Land Rover) has the corresponding VCM2 firmware versions. Software and firmware should be in sync. For example, IDS V86 is compatible with vcm fw: A, and SDD v135 also with vcm fw: A. But if you install IDS v98 for use, then the vcm firmware version would turn B, but the corresponding vcm firmware version remains A, as for SDD v135. The firmware version of IDS and SDD is different. When you convert IDS to SDD, or SDD to IDS, the system would pop up info as below like “VCMII software update”... To ask you to match the firmware with the software.
So for sake of compatibility, to update software.
For vcm2 units, Ford ids v86 had better work with JLR sdd v135,
ids v98 with sdd v140,
For the vcm unit, it’s not allow to update. It’s a must.
