1. Disconnect ECU connector, and making measurements at the connector on the body side wiring harness.

Fig. 95 Actuator Limit Switch:

2. The *1 in the tables above indicates that the limit switch within the actuator is positioned as shown. The actuator selector is at the fully closed position when resistance between terminals 9 and 20 is measured. For this reason, after checking polarity of the tester, the test probe should be connected so current flows from terminal 20 to terminal 9.
3. For terminals marked *2, it is necessary to check individual terminal voltages with the ECU's harness connector connected and the ignition switch in the ON position.
