CIRCUIT OPERATION
This circuit judges the signals of each switch ("ON/
OFF", "CANCEL", "COAST/SET" and "ACC/RES") of
the auto-cruise control switch. The ECM detects the
state of the auto-cruise control switch by sensing the
voltages shown below.

｠

When all switches are OFF: 4.7 - 5.0 volts

｠

When the "ON/OFF" switch is "ON": 0 - 0.5 volt

｠

When the "CANCEL" switch is "ON": 1.0 - 1.8 volts

｠

When the "COAST/SET" switch is "ON": 2.3 - 3.0
volts

｠

When the "ACC/RES" switch is "ON": 3.5 - 4.2 volts

DTC SET CONDITIONS

Check Condition

｠

The "CRUISE" indicator light illuminates.

Judgement Criteria

｠

This DTC will be set when the "COAST/SET" switch
or the "ACC/RES" switch is continuously ON foe 60
seconds or more.
