MULTI--MODE MANUAL TRANSMISSION SYSTEM
COROLLA Supplement (RM1129E)
SYSTEM DESCRIPTION
1.
MULTI--MODE MANUAL TRANSMISSION SYSTEM OUTLINE
(a)
The multi--mode manual transmission has been developed from the conventional manual transmis-
sion by adding actuators directly controlled by electric motors. In addition, an electronic throttle control
system, sensors, a shift lever, and a transmission control ECU are installed to the vehicle. The system
offers automatic clutch operation and two driving modes: automatic shifting (E) mode and manual shift-
ing (M) mode.
(b)
Each actuator stroke sensor is a double non--contact sensor.
(c)
Actuators which have one motor for the clutch and two motors for the shift and select lever shaft (one
for shifting and the other for selecting) have been added to the conventional manual transmission.
The actuators operate to adjust the clutch and move the lever shaft in the selecting or shifting direction.
The transmission control ECU receives information from the ECM and sensors, and simultaneously
controls the engine and multi--mode manual transmission.
(d)
The shift lever features a ”shift--by--wire system” that operates the transmission according to electric
signals.
(e)
The shift lever features an electrical shift lock mechanism. When the engine switch is off or the shift
lever is in ”N” with the engine running and the brake pedal released, the shift lever is locked in the cur-
rent position. The transmission gear and shift position always correspond.
(f)
The multi--mode manual transmission system has a fail--safe function.
When the transmission control ECU detects a malfunction in the system, the ECU illuminates the check
engine warning light (MIL) or sounds the buzzer to let the driver know that a malfunction has occurred.
Under such conditions, the fail--safe function makes it possible to operate the vehicle and avoid an
emergency situation.

FUNCTION OF MAIN COMPONENT
Component
Outline
Meter ECU (Combination Meter)
S
Controls the operation of the indicator lights, warning light, and buzzer.
S
Outputs the vehicle speed signal from the skid control ECU to the transmission control ECU.
Multi--mode Manual Transmission Indicator
(Combination Meter)
Lights up to alert the driver when a malfunction occurs in the multi--mode manual transmission
system.
Gear Position Indicator Light
(Combination Meter)
Indicates the present gear position. In addition, this indicator lights flashes if the actual gear posi-
tion and the shift lever position do not match.
Es Indicator Light (Combination Meter)
Illuminates the indicator, when the sporty [Es] pattern is selected during the normal [E] pattern
driving in E--mode. Not illuminate the indicator while the normal [E] pattern is selected.
Mode Indicator Light (Combination Meter)
Indicates E--mode or M--mode.
Buzzer (Combination Meter)
Sounds if the driver door is opened while the engine is running or the shift lever is in the E, M, or R
position.
Shift Lever Position Sensor
(Shift Lever Assembly)
Outputs the shift lever position or shift request (+ or --) from the ON/OFF combination of 8--contact
switch that is built into the transmission control ECU.
Transmission Shift Main Switch
(Shift Lever Assembly)
Outputs the shift mode (M--mode or E--mode) from the ON/OFF signal to the transmission control
ECU.
Shift Lock Solenoid (Shift Lever Assembly)
Actuated by the transmission control ECU and restricts the movement of the shift lever.
Shift Motor (Shift & Select Actuator)
Actuated by transmission control ECU and effects the select operation of the shift & select lever
shaft.
Shift Stroke Sensor (Shift & Select Actuator)
Detects the length of the shift stroke of the gear shift fork from the rotation angle of the shift &
select lever shaft and relays this information to the transmission control ECU in the form of feed-
back signals.
Select Motor (Shift & Select Actuator)
Actuated by transmission control ECU and effects the select operation of the shift & select lever
shaft.
Select Stroke Sensor (Shift & Select Actuator)
Detects the length of the select stroke of the gear shift fork from the position of the shift & select
lever shaft and relays this information to the transmission control ECU in the form of feedback
signals.
Clutch Motor (Clutch Actuator)
Actuated by transmission control ECU and engages and disengages the clutch.
