(3) Set scan tool MB991958 to data reading mode for cruise

control system (Refer to

P.17-10

.)

• Item 75: Cancel switch.

• When "CANCEL" switch is pressed, the display on

scan tool MB991958 should be "ON".

• When "CANCEL" switch is released, the display on

scan tool MB991958 should be "OFF".

• Item 86: Main switch.

• When "ON/OFF" switch is pressed, the display on

scan tool MB991958 should be "ON".

• When "ON/OFF" switch is pressed again, the display

on scan tool MB991958 should be "OFF".

• Item 91: Resume switch.

• When "ACC/RES" switch is pressed, the display on

scan tool MB991958 should be "ON".

• When "ACC/RES" switch is released, the display on

scan tool MB991958 should be "OFF".

• Item 92: Set switch.

• When "COAST/SET" switch is pressed, the display

on scan tool MB991958 should be "ON".
