3 to D4 at the specified speed?
YES >> GO TO 11.
NO >> Check control valve again.Repair or replace control
valve assembly.
7. CHECK VALVE RESISTANCE
1. Remove control valve assembly. Refer to AT- 4 0 4 , "
Control Valve Assembly and Accumulators" .
–Line pressure solenoid valves
2. Check resistance between terminal cord assembly harness con-
nector terminal and ground.
OK or NG
OK >> GO TO 8.
NG >> Replace solenoid valve assembly.
8. CHECK VALVE OPERATION
1. Remove control valve assembly. Refer to AT- 4 0 4 , "
Control Valve Assembly and Accumulators" .
–Line pressure solenoid valves
2. Check solenoid valve by listening for its operating sound while
applying battery voltage to the terminal and ground.
OK or NG
OK >> GO TO 9.
NG >> Replace solenoid valve assembly.
