I am troubleshooting a persistent parasitic draw on my 1994 Honda Civic 1.6si (D16A9 engine). After removing the aftermarket alarm and power window module, I am still measuring a 0.24A (240mA) draw while the car is off.Before I replace or repair my ICU, I want to confirm if it controls the following features on this specific European/Middle Eastern D16A9 model:

1. Intermittent Wipers: Does the ICU manage the 'INT' timing?
   
2. Warning Chimes: Does it control the "Key-in-Ignition" and "Headlights-on" warning beeps?
   
3. Rear Defogger Timer: Does it handle the auto-off function for the rear glass heater?
   
4. Seatbelt Light: Does it manage the initial warning light/chime?
   
5. Entry Light Delay: Does it provide the dimming effect for the cabin light?
   

None of these features work on my vehicle.
Has anyone experienced a ~240mA leak caused specifically by a failing ICU?
If I bypass the ICU, will the car remain drivable for daily use?

Thanks in advance for your help!
