Actuator Test
1. Disconnect the actuator cable from the actuator rod, and disconnect the 4P connector.
2. Connect battery power to the No.4 terminal and ground to the No.1, No.2, and No.3 terminals.
3. Connect a vacuum pump to the check valve. Then apply vacuum to the actuator.
4. The actuator rod should pull in completely. If the rod pulls in only part-way or not at all, check for a leaking vacuum line or defective solenoid.
