LOCK-UP CONTROL : System Description
INFOID:0000000010622458
SYSTEM DIAGRAM
DESCRIPTION
• Controls for improvement of the transmission efficiency by engaging the torque converter clutch in the
torque converter and eliminating slip of the converter. Achieves comfortable driving with slip control of the
torque converter clutch.
• The oil pressure feed circuit for the torque converter clutch piston chamber is connected to the torque con-
verter clutch control valve. The torque converter clutch control valve is switched by the torque converter
clutch solenoid valve with the signal from TCM. This controls the oil pressure circuit, which is supplied to the
torque converter clutch piston chamber, to the release side or engagement side.
• If the CVT fluid temperature is low or the vehicle is in fail-safe mode due to malfunction, lock-up control is
prohibited.
Lock-up engagement
In lock-up engagement, the torque converter clutch solenoid valve makes the torque converter clutch control
valve locked up to generate the lock-up apply pressure. This pushes the torque converter clutch piston for
engagement.
Lock-up release condition
In lock-up release, the torque converter clutch solenoid valve makes the torque converter clutch control valve
non-locked up to drain the lock-up apply pressure. This does not engage the torque converter clutch piston.
ECO MODE SYSTEM
ECO MODE SYSTEM : System Description
INFOID:0000000010622459
• Driving mode that selects the shift schedule with priority on fuel economy which gives low engine revolution.
• For details on ECO mode control, refer to
DMS-7, "ECO MODE CONTROL : System Description"
• The gear shift line is not changed with the control mode change for the following conditions:
- When the selector lever is in “M” position.

NOTE:
Paddle shifter is applied to vehicle with paddle shifter.
SIGNAL PATH
• The TCM judges the shift position by the transmission range switch signal, manual mode switch signal, non-
manual mode switch signal, manual mode upshift signal, and manual mode downshift signal.
• The TCM transmits the shift position signal to the combination meter via CAN communication. The combina-
tion meter shows the shift position indicator on the information display, according to the signal.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
Description
INFOID:0000000010622463
This system is an on board diagnostic system that records exhaust emission-related diagnostic information
and detects a sensors/actuator-related malfunction. A malfunction is indicated by the malfunction indicator
lamp (MIL) and stored in ECU memory as a DTC. The diagnostic information can be obtained with the diag-
nostic tool (GST: Generic Scan Tool).
GST (Generic Scan Tool)
INFOID:0000000010622464
When GST is connected with a data link connector equipped on the vehicle side, it will communicate with the
control module equipped in the vehicle and then enable various kinds of diagnostic tests. Refer to
NOTE:
Service $0A is not applied for regions where it is not mandated.
