• SRS inflator simulator 07SAZ-TB4011A
• SRS simulator lead H 07YAZ-S3AA100

NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-16) and General Troubleshooting Information
(see page 24-27).

1. Clear the DTC memory (see page 24-28).

2. Turn the ignition switch ON (II), and check that the

SRS indicator comes on for about 6 seconds and
then goes off.

Go to step 3.

Intermittent failure, the system is OK at this

time. Go to Troubleshooting Intermittent Failures
(see page 24-29). If another DTC is indicated,
troubleshoot the DTC.

3. Turn the ignition switch OFF. Disconnect the

negative cable from the battery, and wait for 3
minutes.

4. Check the connection between the floor wire

harness 2P connector and the right side impact
sensor (second) (see page 24-190).

Go to step 5.

Repair the poor connection and retest. If the

DTC 46-1x is still present, go to step 5.

5. Disconnect the floor wire harness 2P connector (A)

from the right side impact sensor (second)
(see page 24-14).

6. Disconnect SRS unit connector C (28P) from the

SRS unit (see step 7 on page 24-26).

7. Measure the resistance between the No. 19 and

No. 20 terminals of SRS unit connector C (28P).
There should be an open circuit or at least 1 M

Go to step 8.

Short in the floor wire harness; replace the

floor wire harness.

8. Measure the resistance between the No. 19

terminal of SRS unit connector C (28P) and body
ground, and between the No. 20 terminal and body
ground. There should be an open circuit or at least
1 M

Go to step 9.

Short to ground in the floor wire harness;

replace the floor wire harness.

9. Reconnect the negative cable to the battery.

10. Turn the ignition switch ON (II).

11. Measure the voltage between the No. 19 terminal

of SRS unit connector C (28P) and body ground,
and between the No. 20 terminal and body ground.
There should be 1 V or less.

Go to step 12.

Short to power in the floor wire harness;

replace the floor wire harness.

12. Turn the ignition switch OFF.

13. Connect the SRS inflator simulator (jumper

connector) and simulator lead H to the floor wire
harness 2P connector (A).

14. Measure the resistance between the No. 19 and

No. 20 terminals of SRS unit connector C (28P).
There should be 1.0

or less.

Faulty right side impact sensor (second) or

SRS unit; replace the right side impact sensor
(second) (see page 24-190). If the problem is still
present, replace the SRS unit (see page 24-188).

Open in the floor wire harness; replace the

floor wire harness.

NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-16) and General Troubleshooting Information
(see page 24-27).

1. Clear the DTC memory (see page 24-28).

2. Turn the ignition switch ON (II), and check that the

SRS indicator comes on for about 6 seconds and
then goes off.

Replace the left or right side impact sensor

(second) (see page 24-190). If the DTC returns,
replace the SRS unit (see page 24-188).

Intermittent failure, the system is OK at this

time. Go to Troubleshooting Intermittent Failures
(see page 24-29). If another DTC is indicated,
troubleshoot the DTC.

NOTE:

• 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
customer if the battery ever went dead or if the
engine was started and run with the battery in a low
state of change. A dead battery may trigger one or
more of these DTCs.

• Before doing this troubleshooting procedure, review

SRS Precautions and Procedures (see page 24-16)
and General Troubleshooting Information (see page
24-27).

1. Clear the DTC memory (see page 24-28).

2. Turn the ignition switch ON (II), and check that the

SRS indicator comes on for about 6 seconds and
then goes off.

Replace the SRS unit (see page 24-188).

Intermittent failure, the system is OK at this

time. Go to Troubleshooting Intermittent Failures
(see page 24-29). If another DTC is indicated,
troubleshoot the DTC.

NOTE:

• Before doing this troubleshooting procedure, review

SRS Precautions and Procedures (see page 24-16)
and General Troubleshooting Information (see page
24-27).

• DTC E4-11: Front left side airbag does not deploy by

OPDS operation.

• DTC F1-11: Driver’s airbag and/or dirver’s seat belt

tensioner deployed.

• DTC F2-11: Front passenger’s airbag and/or front

passenger’s seat belt tensioner deployed.

• DTC F3-11: Driver’s side airbag, left side curtain

airbag, and/or dirver’s seat belt tensioner deployed.

• DTC F4-11: Front passenger’s side airbag, right side

curtain airbag, and/or front passenger’s seat belt
tensioner deployed.

• DTC F5-11: Both or only one side curtain airbag, seat

belt tensioner deployed.

• DTC F6-11: Left side curtain airbag or right side

curtain airbag deployed.

The SRS unit must be replaced after any airbags and/or
tensioners have deployed (see page 24-171).

NOTE: DTC E4-11 is set if the system triggered a
passenger’s side airbag deployment but the airbag was
prevented from deploying by the OPDS. Replace the
right side impact sensor (first) (see page 24-189).

Does the SRS indicator stay on, and is DT C 51-xx,
52-xx, 53-xx, 54-xx, 55-xx, or 56-xx indicated?
