Diagnostic service Function
Service $01 READINESS TESTS This mode gains access to current emission-related data values, including analog inputs
and outputs, digital inputs and outputs, and system status information.
Service $02 (FREEZE DATA) This mode gains access to emission-related data value which were stored by ECM during
the freeze frame. For details, refer to EC-720, "
FREEZE FRAME DATA AND 1ST TRIP
FREEZE FRAME DATA" .
Service $03 DTCs This mode gains access to emission-related power train trouble codes which were stored
by ECM.
Service $04 CLEAR DIAG INFO This mode can clear all emission-related diagnostic information. This includes:
Clear number of diagnostic trouble codes (Service $01)
Clear diagnostic trouble codes (Service $03)
Clear trouble code for freeze frame data (Service $01)
Clear freeze frame data (Service $02)
Reset status of system monitoring test (Service $01)
Clear on board monitoring test results (Service $06 and $07)
Service $06 (ON BOARD TESTS) This mode accesses the results of on board diagnostic monitoring tests of specific com-
ponents/systems that are not continuously monitored.
Service $07 (ON BOARD TESTS) This mode enables the off board test drive to obtain test results for emission-related pow-
ertrain components/systems that are continuously monitored during normal driving condi-
tions.
Service $08 — This mode can close EVAP system in ignition switch ON position (Engine stopped). When
this mode is performed, EVAP canister vent control valve can be closed.
In the following conditions, this mode cannot function.
Low ambient temperature
Low battery voltage
Engine running
Ignition switch OFF
Low fuel temperature
Too much pressure is applied to EVAP system
Service $09 (CALIBRATION ID) This mode enables the off-board test device to request specific vehicle information such
as Vehicle Identification Number (VIN) and Calibration IDs.

CONSULT-II Reference Value in Data MonitorNBS00428
Remarks:
Specification data are reference values.
Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.
i.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the specification da ta in
spite of the ignition timing not being adjusted to the specification data. This IGN TIMING monitors the data calculated by the ECM
according to the signals input from the camshaft position sensor and other ignition timing related sensors.

Major Sensor Reference Graph in Data Monitor ModeNBS004JY
The following are the major sensor reference graphs in “DATA MONITOR” mode.
CLSD THL POS, ACCEL SEN 1, THRTL SEN 1
Below is the data for “CLSD THL POS”, “ACCEL SEN 1” and “THRTL SEN 1” when depressing the accelera-
tor pedal with the ignition switch ON and with selector lever in D position.
The signal of “ACCEL SEN 1” and “THRTL SEN 1” should rise gradually without any intermittent drop or rise
after “CLSD THL POS” is changed from “ON” to “OFF”.
ENG SPEED, MAS A/F SE-B1, THRTL SEN 1, HO2S2 (B1), INJ PULSE-B1
Below is the data for “ENG SPEED”, “MAS A/F SE-B1”, “THRTL SEN 1”, “HO2S2 (B1)” and “INJ PULSE-B1”
when revving engine quickly up to 4,800 rpm under no load after warming up engine sufficiently.
Each value is for reference, the exact value may vary.
