PRECAUTIONS
Revision: 2007 April2007 M35/M45
Precautions NCS001JE

Before connecting or disconnecting the A/T assembly har-
ness connector, turn ignition switch OFF and disconnect
the battery cable from the negative terminal. Because bat-
tery voltage is applied to TCM even if ignition switch is
turned OFF.

After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) Confirmation Procedure”.
If the repair is completed the DTC should not be displayed
in the “DTC Confirmation Procedure”.

When removing the transmission from a vehicle, do not use the
companion flange section at the rear end of the transmission as
a support point. (VK45DE models only)

Always use the specified brand of ATF. Refer to MA-12, "Fluids
and Lubricants" .

Use lint-free paper not cloth rags during work.

After replacing the ATF, dispose of the waste oil using the meth-
ods prescribed by law, ordinance, etc.

Before proceeding with disassembly, thoroughly clean the out-
side of the transmission. It is important to prevent the internal
parts from becoming contaminated by dirt or other foreign mat-
ter.

Disassembly should be done in a clean work area.

Use lint-free paper or towels for wiping parts clean. Common
shop rags can leave fibers that could interfere with the operation
of the transmission.

Place disassembled parts in order for easier and proper assem-
bly.

All parts should be carefully cleaned with a general purpose,
non-flammable solvent before inspection or reassembly.

Gaskets, seals and O-rings should be replaced any time the
transmission is disassembled.

It is very important to perform functional tests whenever they are indicated.

The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.

Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.

Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.

Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.

DTC P1815 MANUAL MODE SWITCH
Revision: 2007 April2007 M35/M45
TCM terminals and data are reference value. Measured between each terminal and ground.
Diagnostic ProcedureNCS001OZ
1. CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis. Refer to AT- 9 2 , "
SELF-DIAGNOSTIC RESULT MODE" .
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 MANUAL MODE SWITCH CIRCUIT
With CONSULT-II
1. Turn ignition switch ON.
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out ON/OFF switching action of “MANU MODE SW”,
“NON M-MODE SW”, “UP SW LEVER”, “DOWN SW LEVER”.
Without CONSULT-II
Drive vehicle in the manual mode, and confirm that the actual gear position and the meter's indication of the
position mutually coincide when the selector lever is shifted to the “+ (up)” or “- (down)” side (1st ⇔ 5th gear).
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. DETECT MALFUNCTIONING ITEM
Check the following.

Manual mode switch. Refer to AT- 1 7 1 , "Component Inspection" .

Pin terminals for damage or loose connection with harness connector.

Open circuit or short to ground or short to power in harness or connector for A/T device (manual mode
switch).

Unified meter and A/C amp. Refer to DI-5, "COMBINATION METERS" .
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
