DIAGNOSIS SYSTEM (TCM)

WORK SUPPORT

SELF DIAGNOSTIC RESULTS

Refer to

TM-109, "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. “ Timing” shows current

malfunction or malfunction in the past.

If current DTC is detected, “timing” is “present”. If the “timing” is “memorized”, it is the malfunction occurred

in the past. According to “ignition counter” in “FFD”, the number (trip) of operation without malfunction of the

DTC can be checked.

• When the DTC at the 1st trip is detected, the “timing” is displayed as “1t”.

DTC deletion method

NOTE:

If the ignition switch is left ON after repair, turn OFF the ignition switch and wait for 10 seconds or more. Then,

turn 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 Pattern A” is displayed

after normal recovery of DTC. Refer to

TM-91, "DIAGNOSIS DESCRIPTION : Counter System"

.

• If malfunction (DTC) is currently detected, “0” is displayed.

• After normal recovery, every time “Driving Pattern A” is satisfied, the display value increases from 1

→ 2 →

3...38

→ 39.

• When MIL turns OFF due to the malfunction and the counter reaches 40, the DTC is erased.

NOTE:

The counter display of “40” cannot be checked.
