(b) Using SST, connect terminals TE1 and E1 of the data
link connector 1.
SST 09843±18020
(c) Maintain engine speed in the range between 900 ±
1,300 rpm for 5 seconds. Check that it returns to idle
speed.
If the engine speed operation is not as specified,
check the IAC valve, wiring and ECM.
ON±VEHICLE INSPECTION
1. INSPECT IAC VALVE OPERATION
(a) Initial conditions:
wEngine at normal operating temperature
wIdle speed set correctly
wTransmission in neutral position
IDLE AIR CONTROL (IAC) VALVE
(d) Remove the SST.
