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.
