After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.
When disconnecting and reconnecting the auxiliary battery.
When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.
After replacing the airbag sensor assembly, refer to work procedure.
Check for DTCs.

Pre-procedure1
Turn the ignition switch off.
Disconnect the cable from the negative (-) auxiliary battery terminal, and wait for at least 60 seconds.
Replace the side airbag pressure sensor RH with a new one or known good one.
When using a new part, since the side airbag pressure sensor LH and RH have the same part number, prepare either one.
Use the prepared side airbag pressure sensor to check the side airbag pressure sensor LH as well.
Connect the cable to the negative (-) auxiliary battery terminal, and wait for at least 2 seconds.
Turn the ignition switch to ON, and wait for at least 60 seconds.
Procedure1
