INFOID:0000000010288394
CAUTION:
• Check for the correct installation status prior to removal or disassembly. If matching marks are
required, be certain they do not interfere with the function of the parts when applied.
• Overhaul should be done in a clean work area, it is preferable to work in dustproof area.
• Before disassembly, using steam or white gasoline, completely remove sand and mud from the exte-
rior of the unit, preventing them from entering into the unit during disassembly or assembly.
• Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace
them with a new one if necessary.
• Gaskets, seals and O-rings should be replaced any time when the unit is disassembled.
• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to out-
side. If tightening sequence is specified, observe it.
• Clean and flush the parts sufficiently and blow-dry them.
• Be careful not to damage sliding surfaces and mating surfaces.
• When applying sealant, remove the old sealant from the mounting surface; then remove any mois-
ture, oil, and foreign materials from the application and mounting surfaces.
• Always use shop paper for cleaning the inside of components.
• Avoid using cotton gloves or shop rags to prevent entering of lint.
• During assembly, observe the specified tightening torque, and apply new gear oil, petroleum jelly, or
multi-purpose grease as specified for each vehicle, if necessary.
Precautions for Removing Battery Terminal
INFOID:0000000010508560
• With the adoption of Auto ACC function, ACC power is automatically supplied by operating the intelligent key
or remote keyless entry or by opening/closing the driver side door. In addition, ACC power is supplied even
after the ignition switch is turned to the OFF position, i.e. ACC power is supplied for a certain fixed time.
• When disconnecting the 12V battery terminal, turn off the ACC
power before disconnecting the 12V battery terminal, observing
“How to disconnect 12V battery terminal” described below.
NOTE:
Some ECUs operate for a certain fixed time even after ignition
switch is turned OFF and ignition power supply is stopped. If the
battery terminal is disconnected before ECU stops, accidental DTC
detection or ECU data damage may occur.
• For vehicles with the 2-batteries, be sure to connect the main bat-
tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be detected.
• After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.
NOTE:
The removal of 12V battery may cause a DTC detection error.
