AUTO-CRUISE VACUUM PUMP

1. Disconnect the vacuum hose from the auto-cruise vacuum

pump and connect a vacuum gauge to the vacuum pump.

2. Disconnect the vacuum pump connector.

3. Check the auto-cruise vacuum pump and valves according

to the following procedure:

(1) Connect the positive battery terminal to auto-cruise

vacuum pump connector terminal 1, and the negative
battery terminal to terminals 2, 3, and 4.
Then the vacuum gauge should read 27 kPa (8.0 in Hg)
or more.

(2) The vacuum should be maintained when terminal 4 is

disconnected from the negative battery terminal while
terminals 1, 2, and 3 remain connected.
Then the vacuum gauge should read 0 kPa (0 in Hg)
when terminal 2 is disconnected from the negative
battery terminal while terminals 1, and 3 remain
connected.

(3) The vacuum should be maintained when terminal 4 is

disconnected from the negative battery terminal while
terminals 1, 2, and 3 remain connected.
Then the vacuum gauge should read 0 kPa (0 in Hg)
when terminal 3 is disconnected from the negative
battery terminal while terminals 1, and 2 remain
connected.

VACUUM ACTUATOR

1. Disconnect the vacuum hose from the vacuum actuator, and

connect a hand vacuum pump to the actuator.

2. Check that the throttle lever operates when applying

vacuum, and the vacuum is maintained.

AUTO-CRUISE CONTROL CHECK

Measure the resistance between the terminals when each of
the "SET," "RESUME," "CANCEL" and "MAIN" switches is
pressed. If the values measured at the time correspond to
those in the table below, the resistance values are correct.
