ON BOARD DIAGNOSTIC (OBD) SYSTEM
ON BOARD DIAGNOST
IC (OBD) SYSTEM
DescriptionINFOID:0000000009464211
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 OBDINFOID:0000000009464212
The GST is connected to the diagnosis connector on t he vehicle and communicates with the on-board control
units to perform diagnosis. The diagnosis connector is the same as for CONSULT. Refer to GI-51, "Function
and System Application".

DIAGNOSIS DESCRIPTION
DIAGNOSIS DESCRIPTION : 1 Tr ip Detection Diagnosis and 2 Trip Detection Diagno-
sis
INFOID:0000000009464213
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-263, "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.

DIAGNOSIS DESCRIPTION : DTC and DTC of 1st TripINFOID:0000000009464214
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-245, "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-279, "Work Flow"
.
DIAGNOSIS DESCRIPTION : Malf unction Indicator Lamp (MIL)INFOID:0000000009464215
• 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-598, "DIAGNOSIS DESCRIPTION : Malfunc-
tion Indicator Lamp (MIL)".
DIAGNOSIS DESCRIPTION : Counter SystemINFOID:0000000009464216
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.

DIAGNOSIS SYSTEM (TCM)
• When the self-diagnosis result is acceptable at the 2nd
trip (conforming to driving condition B), DTC of the
1st trip is erased.
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 t he 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 t he same malfunction, count up the B counter.
• When the B counter reaches 3 wit hout 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.

CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentiall y causing a discharged battery and a no-start condition.

SELF DIAGNOSTIC RESULTS
Display Item List
Refer to
TM-263, "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-243, "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.

Reference ValueINFOID:0000000009464218
CONSULT DATA MONITOR STANDARD VALUE
• In CONSULT, electric shift timing or lock-up timing, i. e. operation timing of each solenoid valve, is displayed.
Therefore, if there is an obvious difference between t he shift timing estimated from a shift shock (or engine
speed variations) and that shown on the CONSULT, the mechanism parts (including the hydraulic circuit)
excluding the solenoids and sensors may be malfunctioning. In this case, check the mechanical parts follow-
ing the appropriate diagnosis procedure.
• Shift point (gear position) displayed on CONSULT slight ly differs from shift pattern described in Service Man-
ual. This is due to the following reasons.
- Actual shift pattern may vary slightly within specified tolerances.
- While shift pattern described in Service Manual indica tes start of each shift, CONSULT shows gear position
at end of shift.
- The solenoid display (ON/OFF) on CONSULT is changed at the start of gear shifting. In contrast, the gear
position display is changed at the time when gear shif ting calculated in the control unit is completed.
