      Front power seat switch LH D89 P V
      CAN main bus line (bus line connecting No. 3 CAN junction connector and No. 1 CAN junction terminal) D90 BR V
      NOTE:

      Do not reconnect the disconnected connectors until this inspection is complete because there may be a short in 2 or more branch lines.

    4. When there is a short in one or more of the branch lines:
      1. Reconnect all of the connectors to the CAN junction connectors, except for the one that was disconnected last (the short-circuited bus line). Check that the resistance shown on the tester is normal (between 54 and 69 Ω) to confirm that there is a short in the one branch line only.

        HINT: 

        • Connectors that connect to the CAN junction connector can be distinguished by the color of their CAN bus lines.
        • Reconnecting the connectors to non-original positions on the CAN junction connector does not affect system performance. However, it is preferred to reconnect the connectors to their original positions to avoid negative effects on the wiring such as tension on the wire harnesses, and to make future maintenance easier.
      Proceed to
