General Precautions

INFOID:0000000009177471

• Turn ignition switch OFF and disconnect the battery cable

from the negative terminal before connecting or disconnect-

ing the CVT assembly harness connector. Because battery

voltage is applied to TCM even if ignition switch is turned

OFF.

• When connecting or disconnecting pin connectors into or

from TCM, do not damage pin terminals (bend or break).

Check that there are not any bends or breaks on TCM pin ter-

minal, when connecting pin connectors.

• Perform TCM input/output signal inspection and check

whether TCM functions normally or not before replacing TCM.

Refer to 

TM-48, "Reference Value"

.

• Perform “DTC (Diagnostic Trouble Code) CONFIRMATION

PROCEDURE”.

If the repair is completed DTC should not be displayed in the

“DTC CONFIRMATION PROCEDURE”.

• Always use the specified brand of CVT fluid. Refer to 

MA-15, "FOR USA AND CANADA : Fluids and Lubri-

cants"

 (For USA and Canada), 

MA-16, "FOR MEXICO : Fluids and Lubricants"

 (For Mexico).

• Use lint-free paper not cloth rags during work.

• Dispose of the waste oil using the methods prescribed by law, ordinance, etc. after replacing the CVT fluid.

PRECAUTIONS

On Board Diagnosis (OBD) System of CVT and Engine

INFOID:0000000009177472

The TCM and ECM have 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 EGR 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.
