NOTE:
Paddle shifter is applied to vehicle with paddle shifter.

SIGNAL PATH

• The TCM judges the shift position by the transmission range switch signal, manual mode switch signal, non-

manual mode switch signal, manual mode upshift signal, and manual mode downshift signal.

• The TCM transmits the shift position signal to the combination meter via CAN communication. The combina-

tion meter shows the shift position indicator on the information display, according to the signal.

ON BOARD DIAGNOSTIC (OBD) SYSTEM

Description

INFOID:0000000010622744

This system is an on board diagnostic system that records exhaust emission-related diagnostic information
and detects a sensors/actuator-related malfunction. A malfunction is indicated by the malfunction indicator
lamp (MIL) and stored in ECU memory as a DTC. The diagnostic information can be obtained with the diag-
nostic tool (GST: Generic Scan Tool).

GST (Generic Scan Tool)

INFOID:0000000010622745

When GST is connected with a data link connector equipped on the vehicle side, it will communicate with the
control module equipped in the vehicle and then enable various kinds of diagnostic tests. Refer to 

GI-52,

"Description"

.

NOTE:
Service $0A is not applied for regions where it is not mandated.

DIAGNOSIS SYSTEM (TCM)

DIAGNOSIS DESCRIPTION

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

INFOID:0000000010622746

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-529, "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.

DIAGNOSIS DESCRIPTION : DTC and DTC of 1st Trip

INFOID:0000000010622747

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-510, "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-541, "Work Flow"

.

DIAGNOSIS DESCRIPTION : Malfunction Indicator Lamp (MIL)

INFOID:0000000010622748

• 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-823, "Malfunction Indicator Lamp"

.

INFOID:0000000010622749

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.

COUNTER SYSTEM LIST

DRIVING CONDITION

Driving condition A

Driving condition A is the driving condition that provides warm-up.
In specific, count-up is performed when all of the following conditions are satisfied.
• Engine speed is 400 rpm or more.
• After start of the engine, the water temperature increased by 20

°

C (36

°

F) or more.

• Water temperature was 70

°

C (158

°

F) or more.

• The ignition switch was changed from ON to OFF.
NOTE:
• If the same malfunction is detected regardless of the driving condition, reset the A counter.
• When the above is satisfied without detecting the same malfunction, count up the A counter.
• When MIL goes off due to the malfunction and the A counter reaches 40, the DTC is erased.

Driving condition B

Driving condition B is the driving condition that performs all diagnoses once.
In specific, count-up is performed when all of the following conditions are satisfied.
• Engine speed is 400 rpm or more.
• Water temperature was 70

°

C (158

°

F) or more.

• In closed loop control, vehicle speed of 70 – 120 km/h (43 – 75 MPH) continued for 60 seconds or more.
• In closed loop control, vehicle speed of 30 – 60 km/h (19 – 37 MPH) continued for 10 seconds or more.
• In closed loop control, vehicle speed of 4 km/h (2 MPH) or less and idle determination ON continued for 12

seconds or more.

• After start of the engine, 22 minutes or more have passed.
• The condition that the vehicle speed is 10 km/h (6 MPH) or more continued for 10 seconds or more in total.
• The ignition switch was changed from ON to OFF.
NOTE:
• If the same malfunction is detected regardless of the driving condition, reset the B counter.
• When the above is satisfied without detecting the same malfunction, count up the B counter.
• When the B counter reaches 3 without malfunction, MIL goes off.
• When the B counter is counted once without detecting the same malfunction after TCM memorizes DTC of

the 1st trip, DTC of the 1st trip is erased.
