It's odd that when swapped to my original speedo and I turned the key on, the "hot" ligth appeared for 1sec and then was replaced by the (correct) "cool" ligth.

Do you think there was something wrong in the ECM? I don't think so because I suppose the speedometer is just receiving signals not sending to the ECM (am I right?).

Do you think the new speedometer is not calibrated properly and reads the same CAN signal as the original speedo but with a different range cool-hot?

Anyway, tomorrow I'm going to swap again to the new speedo and check if the light is still on. Do you have any alternative in case it's still there?

Thanks.

Hopefully the issue is that your coolant temp sensor is actually bad. I have experimented with clusters from other regions and the temperature lights always worked correctly, as the cluster just receives a CAN bus signal from the ECM with the temperature. Definitely not an ECM issue.

Hi CTScott, I don't know the reason but now the light is off.
So it looks like everything is working fine.
Thanks again,

Hello,

If I want to change my VFD speedometer (Yaris 2006) with one newer from (yaris 2009) - I need also the immobilizer?

Thanks,

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.
