Description

Park/neutral position switch (CVT models only)

Park/neutral position switch supplies power to the starter relay in-
side IPDM E/R when the selector lever is shifted to the P or N po-
sition.

IPDM E/R

CPU inside IPDM E/R controls the starter relay. Ignition relay in-
side IPDM E/R supplies power to the Park/neutral position switch
when ignition switch is ON or START.

Starter motor

The starter motor plunger closes and the motor is supplied with
battery power, which in turn cranks the engine, when the “S” ter-
minal is supplied with electric power.
