ACTUATOR TEST

The Actuator Test is used to check the operation of many of the computer-controlled 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 test to energize the relays and solenoids. Check voltages again to determine if they are functioning properly. Remember to write down readings for reference.

Not all vehicles have the same actuators. The tool will not allow the test of actuators not present on the vehicle.

!CAUTION

Some Actuator Tests may activate the fuel pump. Do not disconnect any fuel lines or remove fuel injectors unless it is required by the vehicle service manual. Be sure to reconnect all lines when testing is complete.

!WARNING

Gasoline leaking onto hot engine and exhaust parts can cause fire or other hazardous conditions.
