CAUTION:
• Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.
• Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.
• Be careful not to cut your hand on the heat insulator edge.
• Never use silicon-containing products (e.g. oil) to prevent malfunctions such as the interference with
the conduction of electricity and the occurrence of noise in the radio.
• Prevent rust preventives from adhering to the sensor body.
Precautions for Removing Battery Terminal
INFOID:0000000010665050
• 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.
