TM-92

< SYSTEM DESCRIPTION >

[CVT: RE0F11A]

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 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 10km/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.

DIAGNOSIS SYSTEM (TCM)

SELF DIAGNOSTIC RESULTS

Display Item List

Refer to

TM-112, "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 without malfunction of concerned DTC can be confirmed with

“IGN counter” inside “FFD”.

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

DTC deletion method

NOTE:

• If the battery terminal is disconnected, the TCM memory is erased. (The disconnection time varies from sev-

eral seconds to several hours.

• If the ignition switch is left ON after repair, turn OFF 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-91, "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 the counter reaches 40, the DTC is erased.

NOTE:

The counter display of “40” cannot be checked.
