• CVT detects the vehicle driving status from switc hes, sensors and signals, and controls the vehicle so that
the optimum shift position and shift timing may always be achieved. It also controls the vehicle to reduce
shift and lockup shock, etc.
• Receives input signals from switches and sensors.
• Sends the output signal necessary for operation of so lenoid valves, and evaluates the line pressure, shift
timing, lockup operation, engine brake performance, etc.
• If a malfunction occurs on the electric system, activa te the fail-safe mode only to drive the vehicle.
LIST OF CONTROL ITEMS AND INPUT/OUTPUT
*: If these input/output signals show errors, TCM activates the fail-safe function.
CVT CONTROL SYSTEM : Fail-safeINFOID:0000000009463988
TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically controlled input/output parts is damaged.
If the vehicle shows following behaviors including “poor acceleration”, a malfunction of the applicable system
is detected by TCM and the vehicle may be in a fail-s afe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.

DIAGNOSIS DESCRIPTION
DIAGNOSIS DESCRIPTION : 1 Tr ip Detection Diagnosis and 2 Trip Detection Diagno-
sis
INFOID:0000000009463996
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 memorize s DTC. In these diagnoses, some illuminate MIL and
some do not. Refer to TM-60, "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 drivi ng, 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 TripINFOID:0000000009463997
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 memo rizes DTC of the 1st trip. MIL does not light at this
stage. If the same malfunction is not detected at t he 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-43, "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-77, "Flowchart of Trouble Diagnosis"
.
DIAGNOSIS DESCRIPTION : Malf unction Indicator Lamp (MIL)INFOID:0000000009463998
• TCM not only detects DTC, but also sends the MI L 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-74, "DIAGNOSIS DESCRIPTION : Malfunction
Indicator Lamp (MIL)".
DIAGNOSIS DESCRIPTION : Counter SystemINFOID:0000000009463999
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 DT C of the 1st trip. MIL does not light at this stage.
• If the same malfunction is detect ed at the 2nd trip, TCM memorizes DTC and MIL lights at the same time.
• Then, MIL goes after driving the vehicle for 3 tr ips 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.

SELF DIAGNOSTIC RESULTS
Display Item List
Refer to
TM-60, "DTC Index".
DTC at 1st trip and method to read DTC
• DTC (P0705, P0711, P0720, etc.) is specified by SAE J2012/ISO 15031-6.
• DTC and DTC at 1st trip are displayed on “Self Diagnostic results” of CONSULT.
When DTC is currently detected, “CRNT” is displayed. If “PAST” is displayed, it shows a malfunction
occurred in the past. The trip number of drive wit hout malfunction of concerned DTC can be confirmed with
“IGN counter” inside “FFD”.
• When the DTC at the 1st trip is detected, “1t” is displayed.
DTC deletion method
NOTE:
If the ignition switch is left ON after repair, turn O FF the ignition switch and wait for 10 seconds or more. Then,
turn the ignition ON again. (Engine stop)
1. Touch “TRANSMISSION” of CONSULT.
2. Touch “Self Diagnostic Result”.
3. Touch “Erase”. (DTC memorized in TCM is erased.)
IGN counter
The ignition counter is displayed in “FFD” and the number of times of satisfied “Driving condition A” is dis-
played after normal recovery of DTC. Refer to TM-41, "DIAGNOSIS DESCRIPTION : Counter System"
.
• If malfunction (DTC) is currently detected, “0” is displayed.
• After normal recovery, every time “Driving condition A” is satisfied, the display value increases from 1 → 2 →
3...38 → 39.
• When MIL turns OFF due to the malfunction and t he counter reaches 40, the DTC is erased.
NOTE:
The counter display of “40” cannot be checked.
