4 Check operation of the IAC valve .
PREPARATION:
Remove IAC valve (See page SF−51).
CHECK:
(a) Connect the positive (+) leak from the battery to terminals
5 (B1) and 2 (B2), and the negative ( −) lead to terminals
4 (S1), −1 (S2), −6 (S3), −3 (S4) in that order.
(b) Connect the positive (+) lead from the battery to terminals
5 (B1) and 2 (B2), and the negative ( −) lead to terminals
3 (S4), − 6 (S3), −1 (S2), − 4 (S1) in that order.
OK:
(1) The valve moves to close direction.
(2) The valve moves to open direction.
HINT:
The ACTIVE TEST mode of the T OYOTA hand−held tester can
be used to change the step of the IAC valve as desired.
NG Repair or replace IAC valve.
OK
Check and replace ECM (See page IN−28 ).

DIAGNOSTIC TROUBLE CODE CHART
NOTICE:
When removing the part, turn the ignition switch OFF.
HINT:
Using SST 09843 −18020, connect the terminals Tc and E1, and remove the short pin.
If any abnormality is not found when inspection parts, inspect the ECU.
If a malfunction code is displayed during the DTC check, check the circu\
it listed that the code. For details
of each code, turn to the page referred to under the ”See page” for respective ”DTC N\
