< PRECAUTION >[CVT: RE0F10A]
PRECAUTIONS
Precaution for Procedure without Cowl Top Cover
INFOID:0000000003901480
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Precaution for On Board Diagnosis (OBD) System of CVT and EngineINFOID:0000000003806496
The ECM has an on board diagnostic system. It will light up the Malfunction Indicator Lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
 Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative terminal
before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid
valves, etc. will cause the MIL to light up.
 Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
 Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
 Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system, etc.
 Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Precaution for TCM and CVT Assembly ReplacementINFOID:0000000003806497
CAUTION:
 Check if new data (Unit ID) are entered correctly after replacing CVT assembly and erasing data in
TCM. (Connect CONSULT-III, and then turn ignition switch OFF.)
 When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the
TCM if necessary.

Replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state. (CVT assembly must be replaced
first.)
Not replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state.
Replaced Not replaced RequiredRequired because data has been written in the EE-
PROM in the TCM and because the TCM cannot write
data from the ROM assembly in the transmission.

Judgment Possible cause
Idle speedLow for all positions
(“P”, “R”, “N”, “D”, “L”)Possible causes include malfunctions in the pressure supply system and low oil pump output.
For example
Oil pump wear
 Pressure regulator valve or plug sticking or spring fatigue
 Oil strainer ⇒ oil pump ⇒ pressure regulator valve passage oil leak
 Engine idle speed too low
Only low for a specific
positionPossible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
HighPossible causes include a sensor malfunction or malfunction in the line pressure adjustment
function.
For example
 Accelerator pedal position signal malfunction
 CVT fluid temperature sensor malfunction
 Pressure control solenoid A (line pressure solenoid) malfunction (sticking in OFF state, filter
clog, cut line)
 Pressure regulator valve or plug sticking
Stall speedLine pressure does not
rise higher than the
line pressure for idle.Possible causes include a sensor malfunction or malfunction in the pressure adjustment func-
tion.
For example
 Accelerator pedal position signal malfunction
TCM malfunction
 Pressure control solenoid A (line pressure solenoid) malfunction (shorting, sticking in ON
state)
 Pressure regulator valve or plug sticking
The pressure rises,
but does not enter the
standard position.Possible causes include malfunctions in the pressure supply system and malfunction in the
pressure adjustment function.
For example
 Accelerator pedal position signal malfunction
 Pressure control solenoid A (line pressure solenoid) malfunction (sticking, filter clog)
 Pressure regulator valve or plug sticking
Only low for a specific
positionPossible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
