DTC Troubleshooting (cont’d)
Internal Failure of the
SRS Unit Control Operation Recorded
NOTE:
 Before doing this troubleshooting procedure, review SRS Precautions and Procedures (see page 24-13)
and General Troubleshooting Information (see page
24-22).
 Before troubleshooting any of these DTCs, check the battery/system voltage and battery cable connections.
If the voltage is low, repair the charging system or
replace the battery before troubleshooting the SRS. If
the battery/system voltage is now OK, ask the client if
the battery ever went dead or if the engine was
started and run with the battery in a low state of
changed. A dead battery may trigger one or more of
these DTCs.
1. Clear the DTC memory (see page 24-23).
2. Turn the ignition switch to ON (II), and check that the SRS indicator comes on for about 6 seconds
and then goes off.
Replace the SRS unit (see page 24-203).
Intermittent failure, system is OK at this time.
Go to Troubleshooting Intermittent Failures
(see page 24-24). If another DTC is indicated,
troubleshoot the DTC. NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-13) and General Troubleshooting Information
(see page 24-22).
1. Clear the DTC memory (see page 24-23).
2. Turn the ignition switch to ON (II), then wait for 10 seconds.
3. Read the DTC (see page 24-22).
Faulty SRS unit; replace the SRS unit
(see page 24-203).
Intermittent failure, the system is OK at this
time. Go to Troubleshooting Intermittent Failures
(see page 24-24). If another DTC is indicated,
troubleshoot the DTC.
Does the SRS indicator stay on, and is DT C 51-xx, 52-xx, 53-xx, 54-xx, or 55-xx indicated? Is DTC Ex-11 indicated?
