DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
(a) Disconnect the cable from the negative (-) battery terminal before measuring the resistances of
the CAN main wire and the CAN branch wire.
CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the
SRS system.
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected
.

INSPECTION PROCEDURE
NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
HINT:
Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication
with the CAN, which causes resistance variation.
PROCEDURE
1.
PRECAUTION
NOTICE:
After turning the ignition switch off, waiting time may be required before disconnecting the cable from the
battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice
before proceeding with work
.
