16. Measure the resistance between the No. 11 [No. 6] terminal of right side wire harness 16P connector

C604 and body ground, and between the No. 12 [No. 8] terminal and body ground. There should be an
open circuit or at least 1 Mohms.

Is the resistance as specified?

YES - Short to ground in the left side wire harness; replace the left side wire harness.

NO - Short to ground in the right side wire harness; replace the right side wire harness.

DTC 41-1X ("X" CAN BE 0 THRU 9 OR A THRU F): NO SIGNAL FROM THE LEFT FRONT
IMPACT SENSOR

Special Tools Required



SRS inflator simulator 07SAZ-TB4011A



SRS simulator lead H 07YAZ-S3AA100

1. Clear the DTC memory (see CLEAR THE DTC MEMORY WITH THE HDS ).

2. Turn the ignition switch ON (II), and check that the SRS indicator comes on for about 6 seconds and

then goes off.

Does the SRS indicator stay on, and is DTC 41-1x indicated?

YES - Go to step 3.

NO - Intermittent failure, the system is OK at this time. Go to TROUBLESHOOTING
INTERMITTENT FAILURES . If another DTC is indicated, troubleshoot the DTC.

3. Turn the ignition switch OFF.

4. Disconnect the negative cable from the battery, then wait for 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 COMPONENT
LOCATION INDEX ), and at connector C303 (see ENGINE COMPARTMENT WIRE
HARNESS (LEFT BRANCH) ).

Are the connections OK?

YES - Go to step 6.

NO - Repair the poor connections and retest. If DTC 41-11 is still present, go to step 4.

6. Disconnect the engine compartment wire harness 2P connector (A) from the left front impact sensor.

NOTE:

Before doing this troubleshooting procedure, review SRS Precautions and
Procedures (see PRECAUTIONS AND PROCEDURES ) and General
Troubleshooting Information (see GENERAL TROUBLESHOOTING
INFORMATION ).

7. Disconnect SRS unit connector A (28P) from the SRS unit (see step 7 ).

8. Measure the resistance between the No. 15 and No. 27 terminals of SRS unit connector A (28P).

There should be an open circuit or at least 1Mohms.

Is the resistance as specified?

YES - Go to step 9.

NO - Short in dashboard wire harness A or engine compartment wire harness; replace the faulty
harness.

9. Measure the resistance between the No. 15 terminal of SRS unit connector A (28P) and body ground,

and between the No. 27 terminal and body ground. There should be an open circuit or at least 1
Mohms.

YES - Go to step 10.

NO - Short to ground in dashboard wire harness A or engine compartment wire harness; replace the
faulty harness.

10. Reconnect the negative cable to the battery.

11. Turn the ignition switch ON (II).

12. Measure the for voltage between the No. 15 terminal of SRS unit connector A (28P) and body ground,

and between the No. 27 terminal and body ground. There should be 1 V or less.
