new one should be set to the PRE-SET position. (#Page 65)

The ISC valve can be checked without removing it.
(#Page 41)
If the resistance is not within the standard range, replace the
ISC valve motor assembly with a new one.
Visual inspection
• Remove the screws.
• Check the ISC valve for wear, damage or carbon deposited. If
any defects are found, replace it with a new one.
%
Be careful not to disconnect the ISC valve coupler at
least 5 seconds after ignition switch is turned to OFF.
If the ECM coupler or ISC valve coupler is discon-
nected within 5 seconds after ignition switch is turned
to OFF, there is a possibility of an unusual valve posi-
tion being written in ECM and causing an error of ISC
valve operation.
Normally, the removed O-ring must be replaced with a
new one. However, this O-ring is not available for the
spare parts. If it is found to be damaged, replace the
ISC valve with new one.
