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.

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
.

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