SYSTEM DESCRIPTION
Basic of MPX (Multiplex Communication)
1. General
The SEQUOIA multiplex communication system uses serial communication, which converts multiple pieces
of information into serial communication data. As a result, they can be transmitted through a single commu-
nication wire.
Serial communication data consists of bits and frames. A bit is the basic unit that represents the amount of
information. A bit is represented by a binary value º0º or º1º. A frame is a body of data that is transmitted
together. A frame contains a ºheaderº that indicates the beginning of the data and an ºend messageº that
indicates the end of the data.

Be careful not to damage the camshaft.
(d) Using SST, align the holes of the camshaft main gear and
sub±gear by turning the camshaft sub±gear counter-
clockwise, and temporarily install a service bolt.

TEST
NOTICE:
These tests must be done within 3 to 5 seconds to avoid the
coil to be burned ± out.
1. DO PULL±IN TEST
(a) Disconnect the field coil lead wire from terminal C.
(b) Connect the battery to the magnetic switch as shown.
Check that the pinion gear moves outward.
2. DO HOLDING TEST
While connected as above with the pinion gear out, disconnect
the negative (±) lead from terminal C. Check that the pinion gear
remains out.
3. INSPECT CLUTCH PINION GEAR RETURN
Disconnect the negative (±) lead from the starter body. Check
that the pinion gear returns inward.
4. DO NO±LOAD PERFORMANCE TEST
(a) Connect the battery and ammeter to the starter as shown.
(b) Check that the starter rotates smoothly and steadily with
the pinion gear moving out. Check that the ammeter
shows the specified current.
Specified current:
At 11.5 V: 100 A or less
