[CVT: RE0F11A]

SYSTEM

Provides idle neutral control when stop/start operation is not performed. 

Idle Neutral Control Start Condition

Idle neutral control is started when all of the following conditions are fulfilled. However, during idle neutral con-

trol, idle neutral control is stopped when any of the following conditions is not met or idle neutral control contin-

ues 30 seconds.

NOTE:

Stops or prohibits the idle neutral control when the TCM and ECM detect that the vehicle is in one of the fol-

lowing conditions. 

• Engine coolant temperature and CVT fluid temperature are the specified temperature or more, or the speci-

fied temperature or less.

• When a transaxle malfunction occurs.

• When the vehicle detects DTC and is in the fail-safe mode.

When the idle neutral control finishes, if the vehicle is driven at more than the specified speed and the idle

neutral control start conditions are satisfied, the idle neutral control starts again. If the vehicle has a malfunc-

tion, the idle neutral control does not start.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

ON BOARD DIAGNOSTIC (OBD) SYSTEM

Description

INFOID:0000000009019621

This is an on board diagnosis system which records diagnosis information related to the exhaust gases. It

detects malfunctions related to sensors and actuators. The malfunctions are indicated by means of the mal-

function indicator lamp (MIL) and are stored as DTC in the ECU memory. The diagnosis information can be

checked using a diagnosis tool (GST: Generic Scan Tool).

Function of OBD

INFOID:0000000009019622

The GST is connected to the diagnosis connector on the vehicle and communicates with the on-board control

units to perform diagnosis. The diagnosis connector is the same as for CONSULT. Refer to 

GI-49, "Descrip-

tion"

.

DIAGNOSIS SYSTEM (TCM)

DIAGNOSIS DESCRIPTION
DIAGNOSIS DESCRIPTION : 1 Trip Detection Diagnosis and 2 Trip Detection Diagno-
sis

INFOID:0000000009019623

NOTE:

“Start the engine and turn OFF the ignition switch after warm-up.” This is defined as 1 trip.

1 TRIP DETECTION DIAGNOSIS

When initial malfunction is detected, TCM memorizes DTC. In these diagnoses, some illuminate MIL and

some do not. Refer to 

TM-112, "DTC Index"

.

2 TRIP DETECTION DIAGNOSIS

When initial malfunction is detected, TCM memorizes DTC of the 1st trip. MIL does not light at this stage. <1

trip>

If the same malfunction is detected again in next driving, TCM memorizes DTC. When DTC is memorized, MIL

lights. <2 trip>

“Trip” of the “2 trip detection diagnosis” indicates the driving mode that executes self-diagnosis during driving.

×: Check possible —: Check not possible

DIAGNOSIS DESCRIPTION : DTC and DTC of 1st Trip

INFOID:0000000009019624

2 TRIP DETECTION DIAGNOSIS THAT ILLUMINATES MIL

• The DTC number of the 1st trip is the same as the DTC number.

• When a malfunction is detected at the 1st trip, TCM memorizes DTC of the 1st trip. MIL does not light at this

stage. If the same malfunction is not detected at the 2nd trip (conforming to necessary driving conditions),

DTC at the 1st trip is erased from TCM. If the same malfunction is detected at the 2nd trip, TCM memorizes

DTC and MIL lights at the same time.

• The DTC of the 1st trip is specified in Service $01 of SAE J1979/ISO 15031-5. Since detection of DTC at the

1st trip does not illuminate MIL, warning for a problem is not given to a driver.

• For procedure to delete DTC and 1st trip DTC from TCM, refer to 

TM-93, "CONSULT Function"

.

• If DTC of the 1st trip is detected, it is necessary to check the cause according to the “Diagnosis flow”. Refer

to 

TM-124, "Flowchart of Trouble Diagnosis"

.

DIAGNOSIS DESCRIPTION : Malfunction Indicator Lamp (MIL)

INFOID:0000000009019625

• TCM not only detects DTC, but also sends the MIL signal to ECM through CAN communication. ECM sends

the MIL signal to the combination meter through CAN communication according to the signal, and illumi-

nates MIL.

• For malfunction indicator lamp (MIL) description, refer to 

EC-57, "DIAGNOSIS DESCRIPTION : Malfunction

Indicator Lamp (MIL)"

.

DIAGNOSIS DESCRIPTION : Counter System

INFOID:0000000009019626

RELATION BETWEEN DTC AT 1ST TRIP/DTC/MIL AND DRIVING CONDITIONS (FOR 2 TRIP DE-
TECTION DIAGNOSIS THAT ILLUMINATES MIL)

• When initial malfunction is detected, TCM memorizes DTC of the 1st trip. MIL does not light at this stage.

• If the same malfunction is detected at the 2nd trip, TCM memorizes DTC and MIL lights at the same time.

• Then, MIL goes after driving the vehicle for 3 trips under “Driving condition B” without malfunction.

• DTC is displayed until 40 trips of “Driving condition A” are satisfied without detecting the same malfunction.

DTC is erased when 40 trips are satisfied.
