CLEAR DTC |
Pre-procedure1
(a) Turn the ignition switch off.
(b) Disconnect the cable from the negative (-) auxiliary battery terminal, and wait for at least 60 seconds.
(c) Replace the side airbag pressure sensor RH with a new one or known good one.
HINT:

HINT:
- 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.
(d) Connect the cable to the negative (-) auxiliary battery terminal, and wait for at least 2 seconds.
(e) Turn the ignition switch to ON, and wait for at least 60 seconds.
Procedure1
(f) Clear the DTCs stored in memory.
