CAUTION / NOTICE / HINT
Note
After turning the engine switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.
The vehicle is equipped with a sub-battery. Therefore, ensure there is no power being supplied to the vehicle when disconnecting or reconnecting the connector of the shift control ECU and when removing or installing the shift control ECU.
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
