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.
