and
3
.
3. Connect the positive battery terminal to
the relay terminal
2
.
4. Connect the negative battery terminal to
the relay terminal
4
.
5. Check for continuity between the relay
terminals. Replace if there is no continu-
ity.
6. Check that there is no continuity between
the relay terminals after disconnecting a
battery terminal from the relay terminal
2
or
4
. Replace if there is continuity.
Checking the solenoid valve
1. Connect the special service tool to the
solenoid valve.
2. Apply the specified negative pressure to
the solenoid valve.
3. Check that the solenoid valve opens and
the negative pressure is released when
the battery voltage is applied to the sole-
noid valve terminals
