VHCL SPD CUT
[NON/CUT] • Indicates the vehicle cruise condition.
NON: Vehicle speed is maintained at the ASCD set speed.
CUT: Vehicle speed increased to excessively high compared
with the ASCD set speed, and ASCD operation is cut off.
LO SPEED CUT
[NON/CUT] • Indicates the vehicle cruise condition.
NON: Vehicle speed is maintained at the ASCD set speed.
CUT: Vehicle speed decreased to excessively low compared
with the ASCD set speed, and ASCD operation is cut off.
AT O D M O N I T O R
[ON/OFF] • Indicates [ON/OFF] condition of A/T O/D according to the in-
put signal from the TCM. • For M/T models always “OFF” is displayed
AT OD CANCEL
[ON/OFF] • Indicates [ON/OFF] condition of A/T O/D cancel signal sent
from the TCM. • For M/T models always “OFF” is displayed

[ON/OFF] • Indicates [ON/OFF] condition of CRUISE lamp determined
by the ECM according to the input signals.
SET LAMP
[ON/OFF] • Indicates [ON/OFF] condition of SET lamp determined by the
ECM according to the input signals.
A/F ADJ-B1 • Indicates the correction factor stored in ECM. The factor is
calculated from the difference between the target air/fuel ratio
stored in ECM and the air/fuel ratio calculated from air fuel ra-
tio (A/F) sensor 1 signal.
HO2 S2 DIAG1 (B1)
[INCMP/CMPLT] • Indicates DTC P0139 self-diagnosis (delayed response) con-
dition.

Diagnostic test mode
Function
Service $01 READINESS TESTS This diagnostic service gains access to current emission-related data values, including an-
alog inputs and outputs, digital inputs and outputs, and system status information.
Service $02 (FREEZE DATA) This diagnostic service gains access to emission-related data value which were stored by
ECM during the freeze frame. For details, refer to
EC-612, "
CONSULT-III Function (EN-
GINE)".
Service $03 DTCs This diagnostic service gains access to emission-related power train trouble codes which
were stored by ECM.
Service $04 CLEAR DIAG INFO This diagnostic service can clear all emission-related diagnostic information. This in-
cludes:
• 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)
