GR Yaris PnP Kit Installation Problem

[ml27]

Hi guys,

I'm new to Syvces. I finally received the ECU and get it installed last week. We installed the it as per the Syvces manual and we were able to get the engine up and tuning. However, the dashboard pops up a bunch of malfunction messages and all the warning lights are on and the tachometer, speedometer and indicator are not working. Please see the attached photo which I took it while the engine is running. What could be wrong and how can I fix this?

Thanks in advance.

Do you have the dash can and loom kit fitted? Or have you just plugged in the ECU?

Use an OBD-II scanner to read the codes. Research the specific codes to diagnose the issue, which might be related to improper connections or settings that need to be adjusted in the software. Drive Mad
