lExcept during shift change, the gear position and ATF
pressure switch states are monitored and comparative
judgement made.P1730AT- 1 2 7
A/T 1ST E/BRAKING
lEach ATF pressure switch and solenoid current is moni-
tored and if a pattern is detected having engine braking 1st
gear other than in the “1” position, a malfunction is
detected.P1731AT- 1 3 0
I/C SOLENOID/CIRC

malfunction, cut line, short, or the like
lTCM detects as irregular by comparing target value with
monitor value.P1752AT- 1 3 2
I/C SOLENOID FNCTN
lTCM detects that actual gear ratio is irregular, and relation
between gear position and condition of ATF pressure
switch 3 is irregular during depressing accelerator pedal.

tion of ATF pressure switch 3 is irregular during releasing
accelerator pedal. (Other than during shift change)P1754AT- 1 3 4

FR/B SOLENOID FNCT
lTCM detects that actual gear ratio is irregular, and relation
between gear position and condition of ATF pressure
switch 1 is irregular during depressing accelerator pedal.
(Other than during shift change)
lTCM detects that relation between gear position and condi-
tion of ATF pressure switch 1 is irregular during releasing
accelerator pedal. (Other than during shift change)P1759AT- 1 3 9
D/C SOLENOID/CIRC

short, or the like
lTCM detects as irregular by comparing target value with
monitor value.P1762AT- 1 4 2

FNCTN
lTCM detects that actual gear ratio is irregular, and relation
between gear position and condition of ATF pressure
switch 5 is irregular during depressing accelerator pedal.

tion of ATF pressure switch 5 is irregular during releasing
accelerator pedal. (Other than during shift change)P1764AT- 1 4 4
HLR/C SOL/CIRC
lNormal voltage not applied to solenoid due to functional
malfunction, cut line, short, or the like
lTCM detects as irregular by comparing target value with
monitor value.P1767AT- 1 4 7
HLR/C SOL FNCTN
lTCM detects that actual gear ratio is irregular, and relation
between gear position and condition of ATF pressure
switch 6 is irregular during depressing accelerator pedal.
(Other than during shift change)
lTCM detects that relation between gear position and condi-
tion of ATF pressure switch 6 is irregular during releasing
accelerator pedal. (Other than during shift change)P1769AT- 1 4 9

LC/B SOLENOID FNCT
lTCM detects an improper voltage drop when it tries to
operate the solenoid valve.

tor value, and relation between gear position and actual
gear ratio is irregular.P1774AT- 1 5 4
