Internal Failure of the SRS Unit
NOTE: Before troubleshooting any of these DTCs, check
the battery/system voltage. lf the voltage is low, repair
the charging system or replace the battery before
troubleshooting the SRS. lf the battery/system voltage
is now OK, ask the customer if the battery ever went
oeao,
1. Erase the DTC memory (see page 23-26).
2. Turn the ignition switch ON (ll), and check that the
SRS indicator comes on for about 6 seconds and
then goes off.
Does the SRS indicatot stay on?
YES Replace the SRS unit (see page 23-122).1
NO Intermittent failure, system is OK at this time.
