Do not use ECM ground terminals wh
en measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground ot her than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

• If items or work required are not covered by the
engine section, follow the procedures in the applica-
ble sections.
• Always use the support poin t specified for lifting.
• Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in prepar ation for the backward shif t of center of gravity.
• For supporting points fo r lifting and jacking point at rear axle, refer to GI-38, " Garage Jack and
Safety Stand and 2-Pole Lift " .
