*1: Refer to 

AT-41, "Malfunction Indicator Lamp (MIL)"

 .

*2: These malfunctions cannot be displayed MIL if another malfunction is assigned to MIL.

D/C SOLENOID 
FNCTN

TCM 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. 
(Other than during shift change.)

TCM detects that relation between gear position and condi-
tion of ATF pressure switch 5 is irregular during releasing 
accelerator pedal. (Other than during shift change.)

P1764

P1764*2

AT-151

HLR/C SOL/CIRC

Normal voltage not applied to solenoid due to functional 
malfunction, cut line, short, or the like.

TCM detects as irregular by comparing target value with 
monitor value.

P1767

P1767

AT-153

HLR/C SOL 
FNCTN

TCM 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.)

TCM 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.)

P1769

P1769*2

AT-155

LC/B SOLENOID/
CIRC

Normal voltage not applied to solenoid due to functional 
malfunction, cut line, short, or the like.

P1772

P1772

AT-157

LC/B SOLENOID 
FNCT

TCM detects an improper voltage drop when it tries to oper-
ate 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.

P1774

P1774*2

AT-159

MANU MODE SW/
CIRC

When an impossible pattern of switch signals is detected, a 
malfunction is detected.

P1815

AT-161

ATF PRES SW 1/
CIRC

TCM detects that actual gear ratio is normal, and relation 
between gear position and condition of ATF pressure 
switch 1 is irregular during depressing accelerator pedal. 
(Other than during shift change.)

P1841

AT-165

ATF PRES SW 3/
CIRC

TCM detects that actual gear ratio is normal, and relation 
between gear position and condition of ATF pressure 
switch 3 is irregular during depressing accelerator pedal. 
(Other than during shift change.)

P1843

AT-167

ATF PRES SW 5/
CIRC

TCM detects that actual gear ratio is normal, and relation 
between gear position and condition of ATF pressure 
switch 5 is irregular during depressing accelerator pedal. 
(Other than during shift change.)

P1845

TROUBLE DIAGNOSIS

How to Erase Self-diagnostic Results

1.

Touch “SELF-DIAG RESULTS” on “SELECT DIAG MODE”
screen.

2.

Touch ”ERASE”. (The self-diagnostic results will be erased.)

DATA MONITOR MODE
Operation Procedure

1.

Touch “DATA MONITOR” on “SELECT DIAG MODE” screen.

NOTE:
When malfunctions detected, CONSULT-II performs “REAL-
TIME DIAGNOSIS”. Also, any malfunction detected while in
this mode will be displayed at real time.
