Have to bump the thread again ...

Maybe someone has already tried swapping the control boards between otherwise identical LHD and RHD clusters (83800-0D660-D and 83800-0D650-D) and can confirm that the pinout / PCB routing is different? I have a slight suspicion that the garbled display might have been due to the flex ribbon cable connecting the VFD being improperly mounted.

Also, does anybody know if an analog cluster with part number 83800-0DG30 is compatible with this Yaris:

VNKKL923.. SCP90L-CHMGKW 11/2005 - 10/2008 SCP90 SOL FRP LHD 2SZFE MTM 5F 5D


Many thanks!

For the sake of completeness and in case someone faces that same set of problems:

Control boards from digital RHD and LHD clusters are NOT compatible. The PCBs are completely identical, and they will mechanically fit in both LHD and RHD clusters and thus can be swapped between them. However the firmware is different beyond just computing speed and mileage in MPH or km/h - the VFD component for speed and RPM display (basically everything you see enlarged by the mirror) has a different pin out, and the control board firmware takes that into account. I assume the controllers on that board to be OTP, so no chance of reprogramming even if one were to re-engineer the firmware.

Good job the RHD instrument I bought to try this out on was old and came in under 20. Maybe I can now flog it off on ebay for 5 or something.

The analog cluster 83800-0DG30 on the other hand works just fine in said car. Pinout for the vital indicator LEDs seems to be compatible.

Hi. I'm looking for pinouts for the connectors of an instrument cluster panel for yaris 2015. I've seen the Yaris Instrument Cluster Wiring (USDM vs European vs Japanese) document, but for the PCB I have, D1 has 40 pins, and D2 13 (they also labeled differently - CNA and CNB). Any suggestion of where I could find some schematics would be greatly appreciated. I wasn't able to find anything so far
The part number is 83800-0u191.
