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.

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.

Fail-safe
INFOID:0000000009464219
TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically contro lled 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-sa fe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.

DescriptionINFOID:0000000009464227
Always perform the following items when the TCM is replaced.
SAVING AND WRITING OF TCM DATA• TCM performs accurate control by retrieving data (inher
ent characteristic value) of each solenoid. For this
reason, it is necessary to save data of current TCM in CONSULT before replacing the TCM. After this, the
saved data must be written in new TCM.
Work ProcedureINFOID:0000000009464228
CAUTION:
When replacing TCM together with transaxle assembly, perform “ADDITIONAL SERVICE WHEN
REPLACING TRANSAXLE ASSEMBLY”. Refer to TM-283, "Work Procedure"
.
1.SAVE THE TCM DATA
NOTE:
Save necessary data stored in TCM in CONSULT according to the following instructions:
1. Turn ignition switch OFF and wait for 10 seconds.
2. Turn ignition switch ON.
3. Select “Work Support” in “TRANSMISSION”.
4. Select “READ IP CHARA - REPLACEMENT TCM”.
5. Import data according to the in structions on the CONSULT screen.
>> GO TO 2.
2.REPLACE THE TCM
1. Turn ignition switch OFF and wait for 10 seconds.
2. Replace the TCM. Refer to TM-384, "Removal and Installation"
.
>> GO TO 3.
3.WRITE THE TCM DATA
NOTE:
Write data saved in CONSULT into a new TCM according to the following instructions:
1. Turn ignition switch OFF and wait for 10 seconds.
2. Turn ignition switch ON.
