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 func-
tioning properly. Remember to write down readings for reference.
✓
Not all vehicles have the same actuators. The Scan 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 service man-
ual. 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.
