DIAGNOSTIC FUNCTION

TCM conducts fault detection by monitoring the ter-
minal voltage of the transmission fluid temperature
sensor.

• <P0712>: If transmission fluid temperature

equals or exceeds specified value, TCM judges
that transmission fluid temperature sensor has a
failure.

• <P0713>: If transmission fluid temperature is

below specified value even after test driving for
more than the specified period, the TCM judges
that the transmission fluid temperature sensor
has a failure.

.

DESCRIPTIONS OF MONITOR METHODS
<P0712>

• TCM detects the fluid temperature 180°C (356°F)

or more for 5 seconds.

.

MONITOR EXECUTION <P0712>

• Continuous

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III data list
Item 5: Transmission fluid temperature sensor signal (Refer to
Data List Reference Table

P.23A-127

).

Q: Is the check result normal?

YES : Intermittent malfunction
NO : Go to Step 2.

STEP 2. Check the following connector:

• B-125 Transaxle assembly connector

• C-37 TCM connector

• A-12 Intermediate connector

Check the terminals for a contact status problem and internal
short circuit.
Q: Is the check result normal?

YES : Go to Step 3.
NO : Repair the defective connector.

STEP 3. Check for open circuit and short to ground in the
wiring harness between the CVT assembly connector and
the TCM connector
Between B-125 CVT assembly connector (terminal No.17) and
C-37 TCM connector (terminal No.50)
Q: Is the check result normal?

YES : Go to Step 4.
NO : Repair the wiring harness.

STEP 4. Check for open circuit in the wiring harness
between the CVT assembly connector and the TCM
connector
Between B-125 CVT assembly connector (terminal No.19) and
C-37 TCM connector (terminal No.48)
Q: Is the check result normal?

YES : Go to Step 5.
NO : Repair the wiring harness.

STEP 5. Transmission fluid temperature sensor check
Refer to

P.23A-147

.

Q: Is the check result normal?

YES : Go to Step 6.
NO : Replace the valve body assembly.

STEP 6. Symptom recheck after erasing diagnostic trouble
code
Q: Is the check result normal?

YES : Intermittent malfunction
NO : Replace TCM.
