Glo plug light on 1HDFT

[HDJ80L]

Thanks for posting this @VADUS you guys were on this way earlier, lots of knowledge on the Russian forums.

The reason why I wrote to only remove the permanent power wire "BATT" from the Emission ECU is because that is all thats needed. The other wire "EGR" is just the lowside output for the EVRV VSV, removing this pin is not neccesary - when that VSV is removed that wire is already disconnected.
Sensors can be removed too but need resistors wired in to keep the circuits intact. I've used 1k Ohm from ground to signal and 2k from +5V to signal to keep them around 1.5-2V.

To sum it up:
- VSVs can be removed without resistors they just need the permanent power "BATT" removed from the ECU to prevent code 71 (EGR malfunction)
- Pressure sensor and TPS can be removed but need resistors to prevent codes 31 (Pressure sensor signal) and 41 (Throttle position sensor signal)

I think you are right - removing BATT should be enough to resolve the problem. When I was doing it, i didn't have any schemes - just found the circuits with "+" from fuse ECU_B and eliminated them consistently. Pin with name ERG was first, but it helped only for a first start, then glow lamp started to light again. After that I disconnected the BATT pin, and the problem has gone. Nevertheless, I decided then to keep pin EGR disconnected, since it still could send "+ " to the wiring and removed connectors.
