• The fluid temperature sensor uses a thermistor, and changes the signal voltage by converting changes in the
CVT fluid temperature to a resistance value. TCM evaluates the CVT fluid temperature from the signal volt-
age value.
CVT CONTROL SYSTEM : Secondary Pressure SensorINFOID:0000000012430998
• The secondary pressure sensor is installed to control valve.
• The secondary pressure sensor detects the pressure applied to the secondary pulley.
• When pressure is applied to the ceramic device in the secondary pressure sensor, the ceramic device is deformed, resulting in voltage change. TCM evaluates the secondary pressure from its voltage change. Volt-
age is increased along with pressure increase.
CVT CONTROL SYSTEM : Primar y Pressure Solenoid ValveINFOID:0000000012430999
• The primary pressure solenoid valve is installed to control valve.
• The primary pressure solenoid valve controls the primary pressure control valve. For information about the
primary pressure control valve, refer to TM-73, "
TRANSAXLE : Component Description".
• The primary pressure solenoid valve uses the linear solenoid valve [N/H (normal high) type].
NOTE:
• The principle of the linear solenoid valve utilizes the fa ct that the force pressing on the valve spool installed
inside the coil increases nearly in proportion to the current . This allows it to produce a fluid pressure that is
proportional to this pressing force.
• The N/H (normal high) produces hydraulic control when the coil is not energized.
CVT CONTROL SYSTEM : Low Brake Solenoid ValveINFOID:0000000012431000
• The low brake solenoid valve is installed to control valve.
• The low brake solenoid valve adjusts the tightening pressure of the low brake.

Display Item List
Refer to
TM-110, "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 t he counter reaches 40, the DTC is erased.
NOTE:
The counter display of “40” cannot be checked.
