• If the mode control motor runs smoothly, go to step 4.
4. Measure the resistance between terminals No. 5 and No. 7 of the mode control motor. It should be between 4.2 and 7.8 kO.
5. Reconnect the mode control motor 7P connector, then turn the ignition switch to ON (II).
6. Using the backprobe set, measure the voltage between terminals No. 3 and No. 7 of the 7P connector.
Vent: About 0.5 V
