Operating Inspection (On-Vehicle)
1. Disconnect the terminal component No.1
connector.
Caution
•Do not apply battery positive voltage to
terminals for more than three seconds.
Note
•Because the operation sound of the valves is
small, inspect in a quiet place.
2. Apply battery positive voltage to terminals A, B, C,
D, E, F, G, H, I and battery negative voltage to
GND, and verify that operating sound is heard
from solenoid.
•If the “click” is not heard, inspect the transaxle harness.
—If the transaxle harness is okay, perform the resistance inspection (off-vehicle inspection).
—If there is a problem, repair or replace the transaxle harness.
3. Connect the terminal component No.1 connector.
