Check for open in signal 1 harness
1. Ignition "OFF"
2. Disconnect VIS motor rotation sensor connector
3. Measure resistance between terminal "A" of VIS motor rotation sensor harness connector and "B13" of PCM harness connector.
  Specification: Approx. below 1Ω
4. Is the measured resistance within specifications?
