Toyota RAV4 (XA40) 2013-2018 Service Manual: Electronic control

- Removal and installation of battery
terminal
Notice:
Certain systems need to be initialized after
disconnecting and reconnecting the cable from
the negative (-) battery terminal.
- Before performing electronic work, disconnect
the cable from the negative (-) battery terminal to
prevent component and wire damage caused by
accidental short circuits.
- When disconnecting the cable, turn the ignition
switch off and headlight dimmer switch off
and loosen the cable nut completely. Perform
these operations without twisting or prying the
cable. Then disconnect the cable.
- Clock settings, radio settings, audio system
memory, dtcs and other data are erased when
the cable is disconnected from the negative (-)
battery terminal. Write down any necessary data
before disconnecting the cable.
- Handling of electronic parts

- Do not open the cover or case of the ecu
unless absolutely necessary. If the ic terminals
are touched, the ic may be rendered inoperative
by static electricity.
- Do not pull the wires when disconnecting
electronic connectors. Pull the connector.
- Be careful not to drop electronic components,
such as sensors or relays. If they are dropped
on a hard surface, they should be replaced.
- When cleaning the engine with steam, protect
the electronic components, air filter and
emission-related components from water.
- Never use an impact wrench to remove or install
temperature switches or temperature sensors.
- When measuring the resistance of a wire
connector, insert the tester probe carefully to
prevent terminals from bending.
