  • After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.

    Refer to BEFORE DISCONNECTING BATTERY [11/2023 - ]

    HINT: 

    When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.

    Refer to AUTOMATIC LEARNING CHART [11/2023 - ]

  • After replacing the airbag sensor assembly, refer to work procedure.

    Refer to WORK PROCEDURE [11/2023 - ]

  • Inspect the fuses for circuits related to this system before performing the following procedure.
  • When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.

HINT: 

When the SRS warning light is illuminated due to a drop in supply power voltage, check the vehicle control history (RoB) before performing an inspection as the airbag sensor assembly stores vehicle control history (RoB) (X210B).

Refer to VEHICLE CONTROL HISTORY (RoB) [11/2023 - ]
