CRUISE CONTROL SWITCH CHECK

1. Remove the cruise control switch (Refer to

P.17-68

.)

2. Measure the resistance between terminal number 2 and

terminal number 3 when each of the "ON/OFF", "CANCEL",
"COAST/SET" and "ACC/RES" switches is pressed. If the
values measured at the time each switch is pressed
correspond to those in the table below, the resistance values
are correct.

3. Check that the cruise control switch illuminates when a

positive battery terminal is connected to the connector
terminal number 4, and terminal number 1 is grounded.
