6V DC between terminal @ and terminal @ of the
idle speed control servo connector, and check to be sure
that the idle speed control servo operates.
CautionApply only a 6V DC or lower voltage. Application of
higher voltage could cause locking of the servo gears.
(4)
If not, replace idle speed control servo as an assembly.
CONTROL RELAY
INSPECTION
NWWAE(1) Remove the control relay.
(2) Inspect the continuity between the control relay terminals.

terminal.Caution
Be very careful when connecting the jumper wires
because the relay will be damaged if a mistake is made
with the contact terminals.
(4) With the battery

disconnected, check the continuity between control relay
terminals @-@I.
Continuity between terminals 0-B(5) Use jumper wires to connect control relay terminal
