On-Vehicle Inspection

DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL
CAUTION: Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
NOTE:

- When disconnecting the cable, some systems need to be initialized after the cable is reconnected (See INITIALIZATION ).
