TRANSMISSION CONTROL SYSTEM (AW30–40LE) 7A2-59

DTC P0722 (Flash Code 11)




RTW 77AMF000701

Circuit Description
Vehicle speed information is provided to the TCM by the
output revolution sensor. This sensor is located in the
transmission adapter or extension housing.
The output revolution sensor is an electromagnetic
pulse pickup type that generates a speed signal
according to the revolution of the transmission output
shaft. As a result, the sensor sends a sine wave signal
(AC) to the TCM, which converts this sine wave signal
(pulse voltage) to a RPM signal.
Condition For Running The DTC
All of the following conditions are met.
(1)
All of the following conditions are met for 2
seconds ore more continuously.
• The supply voltage is more than 10.2 volts and less than 15.5 volts.
• DTC U2104 is not detecting failure or not deciding failure.
• DTC U2105 is not detecting failure or not deciding failure

• Engine revolution sensor is not detecting failure
or not deciding failure.
• The engine revolution is more than 550rpm.
(2) Not emergency mode.
(3) All of the following conditions are met. • Device Control is not operating.
• Disable Normal Communication Service is receiving enable.
• DTC Clear is not operating.
Condition For Setting The DTC
All of the following conditions are met.
(1) 25 seconds or more passed after changing to the except P/R/N from P/R/N.
If the following condition is met when 25 seconds
or more passed after changing, it is considered
that 25 seconds or more passed.
• Oil temperature sensor is not detecting failure o
r
not deciding failure, and also oil temperature is
more than 20 °C (68 °F).

TRANSMISSION CONTROL SYSTEM (AW30–40LE) 7A2-63

DTC P0741 (Flash Code 43)






RTW 77ALF001501

Circuit Description
The lock-up solenoid SL of the torque converter clutch
(TCC) controls the lock-up clutch by a signal according
to the lock-up position judgment of the Transmission
Control Module (TCM) when the vehicle runs.
This function can improve the fuel consumption to
almost the same extent as the manual transmission.
The lock-up solenoid SL is put into B+ by the TCM, so
that the solenoid is actuated with the result of lock-up.

Condition For Running The DTC
All of the following conditions are met.
(1)
All of the following conditions are met for 2
seconds or more continuously.
• The supply voltage is more than 10.2 volts and less than 15.5 volts.
• DTC U2104 is not detecting failure or not deciding failure.
• DTC U2105 is not detecting failure or not deciding failure.
• Engine revolution signal is not detecting failure or not deciding failure.
• The engine revolution is more than 550 rpm.
