ACTUATOR TEST

 

TheActuatorTest is used to check the operation of many of he computer-con-

 

 

trolled relays and solenoids. This is also helpful for checking voltages and output

 

 

signals. Use a voltmeter to check the output signals at each relay and solenoid

 

 

to verify their operation. To do this, take voltage readings at relays and solenoids

 

 

before beginning this test. Then activate the

t o energize the relays and sole-

 

 

noids. Check voltages again to determine if they are functioning properly.

 

 

 

Remember to write down readings for refer nce.

 

 

 

 

 

Not all vehicles have the same actuators. The tool will not allow the test

 

 

 

of actuators not present on the vehicle.

 

 

 

 

 

 

 

 

 

Some Actuator Tests may activate the fuel pump. Do not
