NOTE:
The gear ratio is set for each position separately.
System DescriptionINFOID:0000000003806367
In order to select the gear ratio that can obtain the driving force in accordance with driver's intention and the
vehicle condition, TCM monitors the driving conditions, such as the vehicle speed and the throttle position and
selects the optimum gear ratio, and determines the gear change steps to the gear ratio. Then TCM sends the
command to the step motor, controls the inflow/outflow of line pressure from the primary pulley to determine
the position of the moving-pulley and controls the gear ratio.
“D” POSITION
Shifting over all the ranges of gear ratios from the lowest to the high-
est.
SPORT MODE
Use this position for the improved engine braking.
“L” POSITION
By limiting gear range to the lowest position, the strong driving force
and the engine brake can be secured.
DOWNHILL ENGINE BRAKE CONTROL (AUTO ENGINE BRAKE CONTROL)
When a downhill slope is detected with the accelerator pedal released, the engine brake will be strengthened
up by downshifting so as not to accelerate the vehicle more than necessary.

SHIFT CONTROL SYSTEM
ACCELERATION CONTROL
According to vehicle speed and a change of accelerator pedal angle, driver's request for acceleration and driv-
ing scene are judged. This function assists improvement in the acceleration feeling by making the engine
speed proportionate to the vehicle speed. And a shift map that can gain a larger driving force is available for
compatibility of mileage with driveability.

SHIFT LOCK SYSTEM
SHIFT LOCK SYSTEM
System DescriptionINFOID:0000000003806370
The shift lever it cannot be shifted from the “P” position unless the
brake pedal is depressed while the ignition switch is set to ON. The
shift lock is unlocked by turning the shift lock solenoid ON when the
ignition switch is set to ON, the park switch is turned ON (selector
lever is in “P” position), and the stop lamp switch is turned ON (brake
pedal is depressed) as shown in the operation chart in the figure.
Therefore, the shift lock solenoid receives no ON signal and the shift
lock remains locked if all of the above conditions are not fulfilled.
(However, selector operation is allowed if the shift lock release but-
ton is pressed.)
SHIFT LOCK OPERATION at “P” POSITION
When Brake Pedal Is Not Depressed (No Selector Operation Allowed)
The shift lock solenoid (A) is turned OFF (not energized) and the
solenoid rod (B) is extended with the spring when the brake pedal is
not depressed (no selector operation allowed) with the ignition
switch ON.
The connecting lock lever (C) is located at the position shown in the
figure when the solenoid rod is extended. It prevents the movement
of the detent rod (D). The selector lever cannot be shifted from the P
position for this reason.
When Brake Pedal Is Depressed (Shift Operation Allowed)
The shift lock solenoid (A) is turned ON (energized) when the brake
pedal is depressed with the ignition switch ON. The solenoid rod (B)
is compressed by the electromagnetic force. The connecting lock
lever (C) rotates when the solenoid rod is activated. Therefore, the
detent rod (D) can be moved. The selector lever can be shifted to
other positions for this reason.

The shift lock solenoid (A) is not energized when the ignition switch
is in any position other than ON. in this condition, the shift mecha-
nism is locked and “P” position is held. The operation cannot be per-
formed from “P” position if the brake pedal is depressed with the
ignition switch ON when the operation system of shift lock solenoid is
malfunctioning. However, the lock lever (B) is forcibly rotated and the
shift lock is released when the shift lock release button (C) is
pressed from above. Then the selector operation from “P” position
can be performed.
CAUTION:
Use the shift lock release button only when the selector lever cannot be operated even if the brake
pedal is depressed with the ignition switch ON.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
ON BOARD DIAGNOSTIC (OBD) SYSTEM
Diagnosis DescriptionINFOID:0000000003806373
DESCRIPTION
The CVT system has two self-diagnostic systems.
The first is the emission-related on board diagnostic system (OBD) performed by the TCM in combination with
the ECM. A malfunction is indicated by the MI (Malfunction Indicator) and is stored as a DTC in the ECM mem-
ory and in the TCM memory.
The second is the TCM original self-diagnosis performed by the TCM. A malfunction history is stored in the
TCM memory. The detected items are overlapped with OBD self-diagnostic items. For details, refer to TM-204,
"CONSULT-III Function (TRANSMISSION)".
OBD FUNCTION
The ECM provides emission-related on board diagnostic (OBD) functions for the CVT system. One function is
to receive a signal from the TCM used with OBD-related parts of the CVT system. The signal is sent to the
ECM when a malfunction occurs in the corresponding OBD-related part. The other function is to indicate a
diagnostic result by means of the MI (Malfunction Indicator) on the instrument panel. Sensors, switches and
solenoid valves are used as sensing elements.
The MI automatically illuminates in “One or Two Trip Detection Logic” when a malfunction is sensed in relation
to CVT system parts.
ONE OR TWO TRIP DETECTION LOGIC OF OBD
One Trip Detection Logic
If a malfunction is sensed during the first test drive, the MI illuminates and the ECM memory stores the mal-
function as a DTC. The TCM is not provided with such a memory function.
Two Trip Detection Logic
When a malfunction is sensed during the first test drive, it is stored in the ECM memory as a 1st trip DTC
(diagnostic trouble code) or 1st trip freeze frame data. At this point, the MI does not illuminate. — 1st trip
If the same malfunction as that experienced during the first test drive is sensed during the second test drive,
the MI will illuminate. — 2nd trip
The “trip” in the “One or Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation.
OBD DIAGNOSTIC TROUBLE CODE (DTC)
How to Read DTC and 1st Trip DTC
DTC and 1st trip DTC can be read by the following methods.
( with CONSULT-III or GST) CONSULT-III or GST (Generic Scan Tool) Examples: P0705, P0720, etc.
These DTC are prescribed by ISO 15031-6.
(CONSULT-III also displays the malfunctioning component or system.)
1st trip DTC No. is the same as DTC No.
Output of the diagnostic trouble code indicates that the indicated circuit has a malfunction. How-
ever, in case of the Mode II and GST, they do not indicate whether the malfunction is still occurring or
it occurred in the past and has returned to normal.
CONSULT-III can identify them as shown below, therefore, CONSULT-III (if available) is recom-
mended.
- DTC or 1st trip DTC of a malfunction is displayed in SELF-DIAGNOSTIC RESULTS mode for “ENGINE” with
CONSULT-III. Time data indicates how many times the vehicle was driven after the last detection of a DTC.
- If the DTC is being detected currently, the time data will be “0”.
- If a 1st trip DTC is stored in the ECM, the time data will be “1t”.
Freeze Frame Data and 1st Trip Freeze Frame Data The ECM has a memory function, which stores the driving conditions such as fuel system status, calculated
load value, engine coolant temperature, short-term fuel trim, long-term fuel trim, engine speed and vehicle
speed at the moment the ECM detects a malfunction.
Data that are stored in the ECM memory, along with the 1st trip DTC, are called 1st trip freeze frame data,
and the data, stored together with the DTC data, are called freeze frame data and displayed on CONSULT-
III or GST. The 1st trip freeze frame data can only be displayed on the CONSULT-III screen, not on the GST.
For details, refer to EC-113, "
CONSULT-III Function".

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000003806376
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H and CAN-L) allowing a high rate of information transmission with
less wiring. Each control unit transmits/receives data but selectively reads required data only.
