Precautions for Removing Battery Terminal

INFOID:0000000009871458

• When removing the 12V battery terminal, turn OFF the ignition

switch and wait at least 30 seconds.
NOTE:
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption 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.
