Brake D Engaged
WARNING: This page is about a different car, the 2005 Suzuki Reno and 2005 Suzuki Forenza. However, it is still accessible from the selected car via links, so may be relevant.
The line pressure, which engaged clutch B, is also supplied to clutch valve D.
In Reverse, solenoid 1 is switched ON and EDS 4 is switched OFF. This will cause the fluid supplied to the reduction valve to flow to clutch valve D via the EDS 4. The spool of clutch valve D will be depressed allowing fluid to pass to holding valve D.
