HOW TO ERASE DTC (WITH GST)
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10
seconds and then turn it ON (engine stopped) again.
2. Perform “TCM SELF-DIAGNOSTIC PROCEDURE (No Tools)”. Refer to AT- 1 0 2 , "
TCM SELF-DIAGNOS-
TIC PROCEDURE (NO TOOLS)" . (The engine warm-up step can be skipped when performing the diag-
nosis only to erase the DTC.)
3. Select Mode 4 with Generic Scan Tool (GST). For details, refer to EC-129, "
Generic Scan Tool (GST)
Function" (for VQ35DE) or EC-793, "Generic Scan Tool (GST) Function" (for VK45DE).
HOW TO ERASE DTC (NO TOOLS)
The A/T CHECK indicator lamp is located on the instrument panel.
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait at least 10 seconds and then turn it ON (engine stopped) again.
2. Perform “TCM SELF-DIAGNOSTIC PROCEDURE (No Tools)”. Refer to AT- 1 0 2 , "
TCM SELF-DIAGNOS-
TIC PROCEDURE (NO TOOLS)" . (The engine warm-up step can be skipped when performing the diag-
nosis only to erase the DTC.)
3. Perform “OBD-II SELF-DIAGNOSTIC PROCEDURE (No tools)”. Refer to EC-66, "
How to Erase DTC"
(for VQ35DE) or EC-728, "How to Erase DTC" (for VK45DE).
Malfunction Indicator Lamp (MIL)NCS001BB
DESCRIPTION
The MIL is located on the instrument panel.
1. The MIL will light up when the ignition switch is turned ON with- out the engine running. This is a bulb check.
If the MIL does not light up, refer to DI-38, "WARNING LAMPS" ,
or see EC-673, "
MIL AND DATA LINK CONNECTOR" (for
VQ35DE) or EC-1364, "
MIL AND DATA LINK CONNECTOR"
(for VK45DE).
2. When the engine is started, the MIL should go off. If the MIL remains on, the on board diagnostic system has
detected an engine system malfunction.

TROUBLE DIAGNOSISPFP:00004
DTC Inspection Priority ChartNCS001BC
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
NOTE:
If “DTC U1000” is displayed with other DTCs, first perform the trouble diagnosis for “DTC U1000 CAN
COMMUNICATION”. Refer to AT- 1 0 4
.
Fail-safeNCS001BD
The TCM has an electrical fail-safe mode. This mode makes it possible to operate even if there is a an error in
a main electronic control input/output signal circuit.
In fail-safe mode, even if the selector lever is “D” or “M” mode, the transmission is fixed in 2nd, 4th or 5th
(depending on the breakdown position), so the customer should feel “slipping” or “poor acceleration”.
Even when the electronic circuits are normal, under special conditions (for example, when slamming on the
brake with the wheels spinning drastically and stopping the tire rotation), the transmission can go into fail-safe
mode. If this happens, switch OFF the ignition switch for 10 seconds, then switch it ON again to return to the
normal shift pattern. Therefore, the customer's vehicle has returned to normal, so handle according to the
“WORK FLOW” (Refer to AT- 4 6
).
FAIL-SAFE FUNCTION
If any malfunction occurs in a sensor or solenoid, this function controls the A/T to mark driving possible.
Vehicle Speed Sensor
Signals are input from two systems - from vehicle speed sensor A/T (revolution sensor) installed on the trans-
mission and from combination meter so normal driving is possible even if there is a malfunction in one of the
systems. And if vehicle speed sensor A/T (revolution sensor) has unusual cases, 5th gear and manual mode
are prohibited.
Accelerator Pedal Position Sensor
If there is a malfunction in one of the systems, the accelerator opening angle is controlled by ECM according
to a pre-determined accelerator angle to make driving possible. And if there are malfunctions in tow systems,
the engine speed is fixed by ECM to a pre-determined engine speed to make driving possible.
Throttle Position Sensor
If there is a malfunction in one of the systems, the accelerator opening angle is controlled by ECM according
to a pre-determined accelerator angle to make driving possible. And if there are malfunctions in tow systems,
the accelerator opening angle is controlled by the idle signal sent from the ECM which is based on input indi-
cating either idle condition or off-idle condition (pre-determined accelerator opening) in order to make driving
possible.
PNP Switch
In the unlikely event that a malfunction signal enters the TCM, the position indicator is switched OFF, the
starter relay is switched OFF (starter starting is disabled), the back-up lamp relay switched OFF (back-up lamp
is OFF) and the position is fixed to the “D” position to make driving possible.
Starter Relay
The starter relay is switched OFF. (Starter starting is disabled.)

REMOVAL
1. Disconnect lower lever of control device and control rod.
2. Remove manual lever from A/T assembly.
3. Remove control rod from vehicle.
INSTALLATION
Install in reverse order of removal. Be careful of the following:
After installation is completed, adjust and check A/T position. Refer to AT- 2 3 1 , "Adjustment of A/T Posi-
tion" and AT- 2 3 1 , "Checking of A/T Position" .
Adjustment of A/T PositionNCS001I7
1. Loosen nut of control rod.
2. Place PNP switch and selector lever in “P” position.
3. While pressing lower lever toward rear of vehicle (in “P” position direction), tighten nut to the specified torque. Refer to AT- 2 3 0 ,
"CONTROL ROD COMPONENTS" .
CAUTION:
Do not push the bracket.
Checking of A/T PositionNCS001I8
1. Place selector lever in “P” position, and turn ignition switch ON.
2. Check selector lever can be shifted to other than “P” position when brake pedal is depressed. Also check selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move the selector lever and check for excessive effort, sticking, noise or rattle.
4. Check the selector lever stops at each position with the feel of engagement when it is moved through all the positions. Check whether or not the actual position the selector lever is in matches the position shown
by the shift position indicator and the transmission body.
5. The method of operating the lever to individual positions cor- rectly should be as shown in the figure.
6. When selector button is pressed in “P”, “R”, or “N” position with- out applying forward/backward force to selector lever, check but-
ton operation for sticking.
7. Check the back-up lamps illuminate only when lever is placed in the “R” position. Check the back-up lamps does not illuminate
when selector lever is pushed against “R” position in the “P” or
“N” position.
8. Check the engine can only be started with the selector lever in the “P” and “N” positions. (With selector lever in the “P” position,
engine can be started even when selector lever is moved for-
ward and backward.)
9. Check transmission is locked completely in “P” position.
10. When selector lever is set to manual shift gate, check manual mode is displayed on combination meter. Shift selector lever to “+” and “-” sides, and check set shift position changes. (Only while a vehicle is oper-
ating.)

Maintenance of Lubricant Quantity in CompressorNJS000DL
The lubricant in the compressor circulates through the system with the refrigerant. Add lubricant to compres-
sor when replacing any component or after a large refrigerant leakage occurred. It is important to maintain the
specified amount.
If lubricant quantity is not maintained properly, the following malfunctions may result:
Lack of lubricant: May lead to a seized compressor.
Excessive lubricant: Inadequate cooling (thermal exchange interference)

LUBRICANT RETURN OPERATION
Adjust the lubricant quantity according to the test group shown below.

Stop Signal:
At the end of each transmission, a stop operation, in-operation, or internal malfunction message is delivered to
the unified meter and A/C amp. This completes one data transmission and control cycle.
AIR MIX DOOR CONTROL (AUTOMATIC TEMPERATURE CONTROL)
The air mix doors are automatically controlled so that in-vehicle temperature is maintained at a predetermined
value by the temperature setting, ambient temperature, in-vehicle temperature and amount of sunload.
FAN SPEED CONTROL
Blower speed is automatically controlled by the temperature setting, ambient temperature, in-vehicle tempera-
ture, intake temperature, amount of sunload and air mix door position.
With pressing AUTO switch, the blower motor starts to gradually increase air flow volume.
When engine coolant temperature is low, the blower motor operation is delayed to prevent cool air from flow-
ing.
INTAKE DOOR CONTROL
The intake doors are automatically controlled by the temperature setting, ambient temperature, in-vehicle tem-
perature, intake temperature, amount of sunload and ON/OFF operation of the compressor.
MODE DOOR CONTROL
The mode door is automatically controlled by the temperature setting, ambient temperature, in-vehicle temper-
ature, intake temperature and amount of sunload.
