Good Day,

I have been bench testing my Haltech Elite 2000 ecu before I install into my car, my intention were to control the automatic transmission on the RB25DET Neo, I intended use solid state relays to control my transmission solenoids, especially the Line pressure and Torque Converter Lockup solenoids. The issue I have even though the wiring is correct the relay is activated and powers on the test device when it should not be powered on. If I were to switch to a standard 4 pin relay (electro mechanical) the ecu controls it without issue. See my onedrive link below for info on this issue, any assistance would be appreciated. I have two videos in the OneDrive folder that would explain my issue.

You ARE using the correct, 1k Ohm, resistor across the switched input from the ECU? The relay uses an internal optical switch and the LEDs may be getting enough leakage to illuminate and switch the relay on.

What happens when you disconnect one of the switch side terminals? If the relay is still "on", that would suggest a problem with the relay.

Yes, I tested with my multimeter to ensure it is a 1k ohm resistor, if I disconnect pin 4 (switch side) it powers off, my dpo is connected to pin 4.

I forget to power PIN A26.
