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, there is an automatic learning function that completes learning when the respective system is used.
Check for DTCs.

Turn the ignition switch off.
Disconnect the cable from the negative (-) auxiliary battery terminal.
Wait at least 60 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.
Replace the side airbag pressure sensor LH with a new one or known good one.
When using a new part, since the side airbag pressure sensor RH and LH have the same part number, prepare either one.
Use the prepared side airbag pressure sensor to check the side airbag pressure sensor RH as well.
Connect the cable to the negative (-) auxiliary battery terminal.
Turn the ignition switch to ON, and wait for at least 60 seconds.
Clear the DTCs stored in memory.
Turn the ignition switch off.
