negative cable terminal from the batten/.
Caution1. Before connecting or disconnecting the negative
cable, be sure to turn off the ignition switch and thelighting switch.
(If this is not done, there is the possibility of
semiconductor parts being damaged.)
2. For MPI-equipped models, after completion of the
work steps [when the battery’s negative
