The specification (SP) value indicates the tolerance of
the value that is displayed in “SPEC” of “DATA MONI-
TOR” mode of CONSULT during normal operation of the Engine Control System. When the value in “SPEC” of
“DATA MONITOR” mode is within the SP value, the Engine Control System is confirmed OK. When the value
in “SPEC” of “DATA MONITOR” mode is NOT within the SP value, the Engine Control System may have one
or more malfunctions.
The SP value is used to detect malfunctions that may af fect the Engine Control System, but will not light the
MIL.
The SP value will be displayed for the following three items:
• B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board correc- tion)
• A/F ALPHA-B1 (The mean value of air-fuel ratio feedback correction factor per cycle)

Mechanism
It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the steel belt
(the steel plates are placed conti
nuously and the belt is guided with the multilayer steel rings on both sides).
The groove width changes according to wrapping radius of steel belt and pulley from low status to overdrive
status continuously with non-step. It is controlled with the oil pressures of primary pulley and secondary pulley.
Steel belt
It is composed of multiple steel plates (A) and two steel rings (B)
stacked to a several number. The feature of this steel belt transmits
power with compression of the steel plate in contrast with transmis-
sion of power in pulling with a rubber belt. Friction force is required
with the pulley slope to transmit power from the steel plate. The force
is generated with the following mechanism:
Oil pressure applies to the secondary pulley to nip the plate. ⇒The
plate is pushed and extended outward. ⇒The steel ring shows with-
stands. ⇒Pulling force is generated on the steel ring. ⇒ The plate of
the primary pulley is nipped between the pulley. ⇒Friction force is
generated between the steel belt and the pulley.
Therefore, responsibilities are divided by the steel plate that trans-
mits the power with compression and the steel ring that main tains necessary friction force. In this way, the
tension of the steel ring is distributed on the entire su rface and stress variation is limited, resulting in good
durability.
Pulley
The primary pulley (input shaft side) and the secondary pulley (output shaft side) have the shaft with slope
(fixed cone surface), movable sheave (movable cone surface that can move in the axial direction) and oil pres-
sure chamber at the back of the movable sheave.
Pulley gear shifting operation
• Pulley gear shifting operation The movable sheave slides on the shaft to change the groove width of the pulley. Input signals of engine
load (accelerator pedal opening), engine revolution and gear ratio (vehicle speed) change the operation
pressures of the primary pulley and the secondary pulle y, and controls the pulley groove width. Along with
change of the pulley groove width, the belt contact radi us is changed. This allows continuous and stepless
