DTC P1846 ATF PRESSURE SWITCH 6
Revision: 2004 November 2004 FX35/FX45
DTC P1846 ATF PRESSURE SWITCH 6PFP:25240
DescriptionACS007G2
Fail-safe function to detect high and low reverse clutch solenoid valve condition.
CONSULT-II Reference ValueACS007G3
On Board Diagnosis LogicACS007G4

This is not an OBD-II self-diagnostic item.

Diagnostic trouble code “ATF PRES SW 6/CIRC” with CONSULT-II is detected when TCM detects that
actual gear ratio is normal, and relation between gear position and condition of ATF pressure switch 6 is
irregular during depressing accelerator pedal. (Other than during shift change)
Possible CauseACS007G5

ATF pressure switch 6

Harness or connectors
(Switch circuit is open or shorted.)
DTC Confirmation ProcedureACS007G6
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”
and wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Start engine.
2. Accelerate vehicle to maintain the following conditions.
ACCELE POSI: 1.5/8 - 2.0/8
Selector lever: “D” position
Gear position: 2nd
3rd Gear (HLR/C ON/OFF)
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions
required for this test.
3. Perform step “2” again.
4. Turn ignition switch “OFF”, then perform step “1” to “3” again.
5. Check “SELF-DIAG RESULTS” mode for “A/T” with CONSULT-
II.
If DTC (P1846) is detected, go to AT- 1 8 5 , "
Diagnostic Procedure" .
If DTC (P1767) is detected, go to AT- 1 6 5 , "
Diagnostic Procedure" .

A/T CHECK Indicator Lamp Does Not Come OnACS007GD
SYMPTOM:
A/T CHECK indicator lamp does not come on for about 2 seconds when turning ignition switch to
“ON”.
DIAGNOSTIC PROCEDURE
1. CHECK CAN COMMUNICATION LINE
Perform self-diagnosis. Refer to AT- 9 4 , "
SELF-DIAGNOSTIC RESULT MODE" , AT- 1 0 3 , "TCM SELF-DIAG-
NOSTIC PROCEDURE (NO TOOLS)" .
Is a malfunction in the CAN communication indicated in the results?
YES >> Check CAN communication line. Refer to AT- 1 0 5 , "DTC U1000 CAN COMMUNICATION LINE" .
NO >> GO TO 2.
2. CHECK TCM POWER SOURCE
1. Disconnect A/T assembly harness connector.
2. Turn ignition switch ON. (Do not start engine.)
3. Check voltage between A/T assembly harness connector termi-
nals and ground. Refer to AT-130, "
Wiring Diagram — AT —
POWER" .
4. Turn ignition switch OFF.
5. Check voltage between A/T assembly harness connector termi-
nals and ground. Refer to AT-130, "
Wiring Diagram — AT —
POWER" .
OK or NG

DISPLAY SCREEN
Displays the operational status of the system.
AUTO SWITCH

The compressor, intake doors, air mix doors, outlet doors and blower speed are automatically controlled
so that the in-vehicle temperature will reach, and be maintained at the set temperature selected by the
operator.

When pressing AUTO switch, air inlet, air outlet, fan speed, and discharge air temperature are automati-
cally controlled.
TEMPERATURE SWITCH (POTENTIO TEMPERATURE CONTROL) (DRIVER SIDE)
Increases or decreases the set temperature.
TEMPERATURE SWITCH (POTENTIO TEMPERATURE CONTROL) (PASSENGER SIDE)

Increases or decreases the set temperature.

When the temperature switch is pressed, the dual switch indicator will automatically illuminate.
RECIRCULATION (REC) SWITCH

When REC switch is ON, REC switch indicator turns ON, and air inlet is fixed to REC.

When REC switch is ON and is pressed for approximately 1.5 seconds or longer, REC and FRE switch
indicators blink twice. Then, automatic control mode is entered. Inlet status is displayed even during auto-
matically controlled.

When FRE switch is turned ON, or when compressor is turned from ON to OFF, REC switch is automati-
cally turned OFF (fixed to FRE mode). REC mode can be re-entered by pressing REC switch again.

REC switch is not operated when DEF switch is turned ON, or at the D/F position.
FRESH (FRE) SWITCH

When FRE switch is ON, FRE switch indicator turns ON, and air inlet is fixed to FRE.

When FRE switch is ON and is pressed for approximately 1.5 seconds or longer, REC and FRE switch
indicators blink twice. Then, automatic control mode is entered. Inlet status is displayed even during auto-
matically controlled.

When REC switch is turned ON, FRE switch is automatically turned OFF (fixed to REC mode). FRE mode
can be re-entered by pressing FRE switch again.
DEFROSTER (DEF) SWITCH
Positions the air outlet doors to the defrost position. Also positions the intake doors to the fresh air position.
REAR WINDOW DEFOGGER SWITCH
When illumination is ON, rear window is defogged.
OFF SWITCH
The compressor and blower are OFF, the intake doors are set to the fresh air position, and the air outlet doors
are set to the foot (75% foot and 25% defrost) position.
A/C SWITCH
The compressor is ON or OFF.
(Pressing the A/C switch when the AUTO switch is ON will turn off the A/C switch and compressor.)
MODE SWITCH
Controls the air discharge outlets.
FAN SWITCH
Manually control the blower speed. Seven speeds are available for manual control (as shown on the display
screen).
DUAL SWITCH (WITH LEFT AND RIGHT VENTILATION TEMPERATURE SEPARATELY CON-
TROL SYSTEM)

When the DUAL switch indicator is not illuminated and the DUAL switch is pressed, the driver-side setting
temperature and passenger-side setting temperature can each be set independently.

When the DUAL switch indicator is illuminated and the DUAL switch is pressed, the driver-side setting
temperature are applied to both sides.

FUNCTION CONFIRMATION PROCEDURE
1. SET IN SELF-DIAGNOSTIC MODE
1. Turn ignition switch ON.
2. Set in self-diagnostic mode as follows. Within 10 seconds after starting engine (ignition switch is turned
ON.), press OFF switch for at least 5 seconds.
CAUTION:

If battery voltage drops below 12V during diagnosis STEP-3, actuator speed becomes slower and
as a result, the system may generate an error even when operation is usual. To avoid this, start
engine before performing this diagnosis.

Former STEP-1 (LEDs and display screen are checked) does not exist in this self-diagnosis func-
tion.
>> GO TO 2.
2. STEP-2: SENSOR CIRCUITS ARE CHECKED FOR OPEN OR SHORT CIRCUIT
Does code No. 20 appear on the display?
YES >> GO TO 3.
NO >> GO TO 13.
3. CHECK TO ADVANCE SELF-DIAGNOSIS STEP-3

YES >> GO TO 4.
NO >> Malfunctioning OFF switch or unified meter and A/C amp. Refer to ATC-102, "
Self-diagnosis" .
4. CHECK TO RETURN SELF-DIAGNOSIS STEP-2
Press temperature (DOWN) switch (driver side).
Return to self
-diagnosis STEP-2?
YES >> GO TO 5.
NO >> Replace A/C and AV switch. Temperature switch malfunctions.
5. STEP-3: MODE DOOR AND INTAKE DOOR POSITIONS ARE CHECKED
Press temperature (UP) switch (driver side).
