TM-73

TORQUE CONVERT-
ER

• A/T cannot perform lock-up even if electrical circuit is

good.

• TCM detects as irregular by comparing difference val-

ue with slip rotation.

P0744

TM-75

PC SOLENOID A

• Normal voltage not applied to solenoid due to cut line,

short, or the like

• TCM detects as irregular by comparing target value

with monitor value.

TM-77

TP SENSOR

• TCM does not receive the proper accelerator pedal po-

sition signals (input by CAN communication) from
ECM.

TM-79

TRANS FLUID TEMP
SEN

• During running, the ATF temperature sensor signal

voltage is excessively high or low

• A/T fluid temperature does not rise to the specified

temperature after driving for a certain period of time.

• There is a certain temperature difference between A/

T fluid and engine coolant.

P1710

P0710

TM-82

VEHICLE SPEED SIG-
NAL

• Vehicle speed signal (CAN communication) from com-

bination meter not input due to cut line or the like

• Unexpected signal input during running

TM-84

INTERLOCK

• Except during shift change, the gear position and ATF

pressure switch states are monitored and comparative
judgment made.

P1730

P1730

TM-86

1GR E/BRAKING

• Each ATF pressure switch and solenoid current is

monitored and if a pattern is detected having engine
braking 1GR other than in the "1" position, a malfunc-
tion is detected.

L C BRAKE SOLENOID

• TCM detects an improper voltage drop when it tries to

operate the solenoid valve.

• Condition of ATF pressure switch 2 is different from

monitor value, and relation between gear position and
actual gear ratio is irregular.
