I am not sure how to do that in the IIDTool menu. Do tell...
Sure thing...
From the current manual, page 63:
RLM Suspension ECU (L322-06 and L319-04)
User can choose between the Hitachi and AMK (introduced in 2012 as the new replacement part) compressor firmware. The firmware for vehicles fitted with the Hitachi compressor contains modifications on the compressor logic and temperature thresholds. Re-flashing the suspension ECU takes around one minute.
Identify firmware: This function will return which firmware is currently in the Suspension ECU (Hitachi or AMK).
So, do this
Main Menu > ECU Flash > RLM-Suspension > Identify Actual Firmware
