PRECAUTIONS
• Be sure to turn the ignition switch OFF and disconnect battery negative cable from battery 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 connectors are 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 erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
PrecautionINFOID:0000000001703154
•Before connecting or disconnecting the TCM harness connec-
tor, turn ignition switch OFF and disconnect the battery cable
from the negative terminal. Failure to do so may damage the
TCM. Because battery voltage is applied to TCM even if igni-
tion switch is turned off.
•When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM pin
terminal, when connecting pin connectors.
•Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly or
not. (See page AT-71, "
TCM Terminal and Reference Value".)
•After performing each TROUBLE DIAGNOSIS, perform “DTC
(Diagnostic Trouble Code) Confirmation Procedure”.
The DTC should not be displayed in the “DTC Confirmation
Procedure” if the repair is completed.
• Before proceeding with disassembly, thoroughly clean the outside
of the transaxle. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
• Disassembly should be done in a clean work area.
• Use lint-free cloth or towels for wiping parts clean. Common shop
rags can leave fibers that could interfere with the operation of the A/T.
• Place disassembled parts in order for easier and proper assembly.
• All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.
• Gaskets, seals and O-rings should be replaced any time the A/T is disassembled.
• It is very important to perform functional tests whenever they are indicated.
• The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent springs
and small parts from becoming scattered or lost.
• Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
