Fast Idle Cam (FIC)
COMPONENT DESCRIPTIONNEEC0502The FIC is installed on the throttle body to maintain adequate
engine speed while the engine is cold. It is operated by a volumet-
ric change in wax located inside the thermo-element. The thermo-
element is operated by engine coolant temperature.
For inspection refer to ªTROUBLE DIAGNOSIS-BASIC
INSPECTIONº, ªBasic Inspectionº, EC-3086.

models with CONSULT-II.
SRT Set TimingNEEC0031S0310SRT is set as ªcompleteº after self-diagnosis has been performed one or more times. Completion of SRT will
occur if the result is OK or NG. The set timing is different between them and is shown in the following table.

*1: This item includes 1st trip DTCs.
*2: This mode includes 1st trip freeze frame data or freeze frame data. The items appear on CONSULT-II screen in freeze frame data
mode only if a 1st trip DTC or DTC is detected. For details, refer to EC-3050.
FUNCTIONNEEC0034S03
Diagnostic test mode Function
Work supportThis mode enables a technician to adjust some devices faster and more accurately by following the
indications on the CONSULT-II unit.
Self-diagnostic resultsSelf-diagnostic results such as 1st trip DTC, DTCs and 1st trip freeze frame data or freeze frame
data can be read and erased quickly. *1
Data monitor Input/Output data in the ECM can be read.
Data monitor (SPEC)Input/Output of the specification for the basic fuel schedule, AFM, A/F, feedback control valve and
the other data monitor items can be read.
Active testDiagnostic Test Mode in which CONSULT-II drives some actuators apart from the ECMs and also
shifts some parameters in a specified range.
SRT confirmation The status of system monitoring tests and the self-diagnosis status/result can be confirmed.
Function test This mode is used to inform customers when their vehicle condition requires periodic maintenance.
ECM part number ECM part numbers can be read.
*1 The following emission-related diagnostic information is cleared when the ECM memory is erased.
1) Diagnostic trouble codes
2) 1st trip diagnostic trouble codes
3) Freeze frame data
4) 1st trip freeze frame data
