DTC P1754 INPUT CLUTCH SOLENOID VALVE FUNCTION
DTC P1754 INPUT CLUTCH SOLENOID VALVE FUNCTION
PFP:31940
DescriptionECS00FZW
lInput clutch solenoid valve is controlled by TCM in response to signals sent from PNP switch, vehicle
speed sensor and accelerator pedal position sensor. Gears will then be shifted to the optimum position.
lThis is not only caused by electrical malfunction (circuits open or shorted) but also by mechanical mal-
function such as control valve sticking, improper solenoid valve operation.
CONSULT-II Reference ValueECS00FZX
On Board Diagnosis LogicECS00FZY
Diagnostic trouble code “P1754 I/C SOLENOID FNCTN” with CONSULT-II or 5th judgement flicker without
CONSULT-II is detected under the following conditions.
lWhen TCM 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. (Other than during shift change)
lWhen TCM detects that relation between gear position and condition of ATF pressure switch 3 is irregular
during releasing accelerator pedal. (Other than during shift change)
Possible CauseECS00FZZ
lHarness or connectors
(The solenoid and switch circuits are open or shorted.)
lInput clutch solenoid valve
lATF pressure switch 3
DTC Confirmation ProcedureECS00G00
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
SLCT LVR POSI: “D” position
GEAR: “3”
“4” (I/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 (P1754) is detected, go toAT- 1 3 5 , "
Diagnostic Procedure".
If DTC (P1752) is detected, go toAT- 1 3 3 , "

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EJS006AK
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Working with HFC-134a (R-134a)EJS006AL
WARNING:
lCFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. These refrigerants
must never be mixed, even in the smallest amounts. If the refrigerants are mixed and compressor
malfunction is likely occur.
lUse only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo-
nents. If lubricant other than that specified is used, compressor malfunction is likely to occur.
lThe specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol-
lowing handling precautions must be observed:
–When removing refrigerant components from a vehicle, immediately cap (seal) the component to
minimize the entry of moisture from the atmosphere.
–When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just
before connecting the components. Connect all refrigerant loop components as quickly as possi-
ble to minimize the entry of moisture into system.
–Only use the specified lubricant from a sealed container. Immediately reseal containers of lubri-
cant. Without proper sealing, lubricant will become moisture saturated and should not be used.
–Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refriger-
ant. If accidental system discharge occurs, ventilate work area before resuming service. Addi-
tional health and safety information may be obtained from refrigerant and lubricant
manufacturers.
–Do not allow lubricant (Nissan A/C System Oil Type S) to come in contact with styrofoam parts.
Damage may result.
Contaminated RefrigerantEJS006AM
If a refrigerant other than pure HFC-134a (R-134a) is identified in a vehicle, your options are:
lExplain to the customer that environmental regulations prohibit the release of contaminated refrigerant
into the atmosphere.
lExplain that recovery of the contaminated refrigerant could damage your service equipment and refriger-
ant supply.
lSuggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
lIf you choose to perform the repair, recover the refrigerant using onlydedicated equipment and contain-
ers. Do not recover contaminated refrigerant into your existing service equipment.If your facility
does not have dedicated recovery equipment, you may contact a local refrigerant product retailer for avail-
able service. This refrigerant must be disposed of in accordance with all federal and local regulations. In
addition, replacement of all refrigerant system components on the vehicle is recommended.
