ASCD INDICATOR

Description

INFOID:0000000004212193

ASCD indicator lamp illuminates to indicate ASCD operation status. Lamp has two indicators, CRUISE and

SET, and is integrated in combination meter.

CRUISE lamp illuminates when MAIN switch on ASCD steering switch is turned ON to indicated that ASCD

system is ready for operation.

SET lamp illuminates when following conditions are met. 

• CRUISE lamp is illuminated.

• SET/COAST switch on ASCD steering switch is turned ON while vehicle speed is within the range of ASCD

setting.

SET lamp remains lit during ASCD control.

Refer to 

EC-45, "System Description"

 for the ASCD function.

MALFUNCTION INDICATOR LAMP

MALFUNCTION INDICATOR LAMP

Description

INFOID:0000000004212196

The Malfunction Indicator Lamp (MIL) is located on the combination

meter.

The MIL will light up when the ignition switch is turned ON before the

READY operation light comes on. This is a bulb check.

When the ignition switch is turned ON (READY) and READY opera-

tion light turns on, the MIL should go off. If the MIL remains on, the

on board diagnostic system has detected a system malfunction.

For details, refer to 

HBC-590, "Diagnosis Procedure"

.

TERMINAL LAYOUT

PHYSICAL VALUES

NOTE:

• The hybrid vehicle control ECU is located behind the passenger side instrument lower panel. For this inspec-

tion, remove passenger side instrument lower panel.

• Specification data are reference values and are measured between each terminal and ground.

• Pulse signal is measured by CONSULT-III.

CAUTION:

Do not use the hybrid vehicle control ECU ground terminals when measuring input/output voltage.

Doing so may result in damage to the hybrid vehicle control ECUs transistor. Use a ground other than

the hybrid vehicle control ECU terminals, such as the ground.
