Mitsubishi Outlander XL. Manual - part 877

｠

The  passenger’s  air  bag  OFF  indicator  light
illuminates when the ignition switch is turned to the
"ON"  position  and  goes  out  after  approximately
seven seconds if there is not a malfunction in the
SRS system.

｠

If a failure occurs in the system, the SRS-ECU will
stop sending that SRS warning light "OFF" signal,
thus  causing  the  combination  meter  to  illuminate
the SRS warning light.

｠

The SRS warning light "OFF" signal is not sent to
the combination meter in the cases below, either.
Therefore, the combination meter will illuminate the
SRS warning light.

｠

The SRS-ECU connector is disconnected.

｠

The SRS-ECU is not working normally due to a
failure in its power supply lines.

｠

The  wiring  harness  between  the  passenger’s
air bag OFF indicator light and the SRS-ECU is
broken.

DTC SET CONDITIONS
This DTC will be set if an open circuit has occurred in
the wiring harness between the passenger’s air bag
OFF indicator light and the SRS-ECU.
