Precautions for Removing Battery Terminal

INFOID:0000000010763741

• 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.

HOW TO DISCONNECT 12V BATTERY TERMINAL

Disconnect 12V battery terminal according to Instruction 1 or Instruction 2 described below.
For vehicles parked by ignition switch OFF, refer to Instruction 2.

INSTRUCTION 1

Open the hood.

Turn key switch to the OFF position with the driver side door opened.

Get out of the vehicle and close the driver side door.

Wait at least 3 minutes.

CAUTION:

While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

INSTRUCTION 2 (FOR VEHICLES PARKED BY IGNITION SWITCH OFF)

Unlock the door with intelligent key or remote keyless entry.
NOTE:
At this moment, ACC power is supplied.

Open the driver side door.

Open the hood.

Close the driver side door.

Wait at least 3 minutes.

CAUTION:

While waiting, never operate the vehicle such as locking, opening, and closing doors. Violation of
this caution results in the activation of ACC power supply according to the Auto ACC function.

Remove 12V battery terminal.

CAUTION:

After installing 12V battery, always check self-diagnosis results of all ECUs and erase DTC.

Service Notice or Precautions for Propeller Shaft

INFOID:0000000010763742

• Replace the propeller shaft assembly if there is a breakage or deflection on tube.

SEF289H

DLN-182

< PRECAUTION >

[REAR PROPELLER SHAFT: C-CVJ-C]

PRECAUTIONS

• Never hit the tube or apply an impact on it during repair service. Never damage the tube as well.
• The joint cannot be disassembled. Never disassemble it.
• If constant velocity joint was bent during propeller shaft assembly removal, installation, or transportation, its

boot may be damaged. Wrap boot interference area to metal part with shop cloth or rubber to protect boot
from breakage.

LOOSENESS OF CONNECTED PART

Check each fixing bolt and nut for looseness using torque wrench. For each tightening torque, refer to

DLN-

186, "Exploded View"

BACKLASH OF JOINT PART

Move the joint of propeller shaft up and down and from side to side
(axial direction of shaft and right angle to shaft) to check that the joint
has no backlash. If the joint has a malfunction, remove propeller
shaft and perform inspection.

BACKLASH OF CENTER BEARING

Move the shaft near center bearing up and down and from side to
side (axial direction of shaft and right angle to shaft) to check that the
bearing has no backlash. If the bearing has a malfunction, remove
propeller shaft and perform inspection.

APPEARANCE AND NOISE

• Check the propeller shaft tube surface for dents or cracks. If malfunction is detected, replace propeller shaft

assembly.

• If center bearing is noisy or damaged, replace propeller shaft assembly.

VIBRATION

If vibration is present at high speed, adjust the propeller shaft phase first.
1.

Check the propeller shaft for bend and damage. If damaged, replace propeller shaft assembly.

Perform a cruise test drive to check the propeller shaft for runout. If vibration occurs, separate propeller
shaft at final drive companion flange; then change the phase between electric controlled coupling stud bolt
and propeller shaft by the one bolt hole at a time and install propeller shaft.

If vibration is still detected, measure propeller shaft runout after removing it. Refer to

DLN-189, "Inspec-

tion"
