NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-13), General Troubleshooting Information (see page
24-22), and Battery Terminal Disconnection and
Reconnection (see page 22-68). 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.
Go to step 3.
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.
3. Turn the ignition switch to LOCK (0).
4. Disconnect the negative cable from the battery, then wait at least 3 minutes.
5. Check the connections between SRS unit connector A (28P) and the SRS unit, between the engine
compartment wire harness 2P connector and the
left front impact sensor (see page 24-11), and at
connector C203 (see page 22-22).
Go to step 6.
Repair the poor connections, clear the DTC,
and retest. If DTC 41-1x is still present, go to step 6. 6. Disconnect the engine compartment wire harness
2P connector (A) from the left front impact sensor.
7. Disconnect SRS unit connector A (28P) from the SRS unit (see step 9 on page 24-21).
8. Measure the resistance between SRS unit connector A (28P) terminals No. 15 and No. 27.
There should be an open circuit or at least 1 M .
Go to step 9.
Short in the engine compartment wire
harness or dashboard wire harness; replace the
faulty harness, then clear the DTC.

Does the SRS indicator stay on, and is DT C 41-1x indicated?
Ar e t he connect i ons OK ? Is the resistance as specif ied?

Faulty left front impact sensor or SRS unit;
replace the left front impact sensor (see page
24-210), then clear the DTC. If the problem is still
present, replace the SRS unit (see page 24-203).
Poor connection at C 203, open in engine
compartment wire harness, or open in dashboard
wire harness. Inspect C203 (see page 22-22). If it is
OK, replace the faulty harness, then clear the
DTC.  SRS inflator simulator 07SAZ-TB4011A
