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