Is the resistance as specified?

YES -Go to step 14.

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

14. Reconnect the negative cable to the battery.
15. Turn the ignition switch ON (II).
16. Measure the voltage between the No. 25 terminal of SRS unit connector B

(28P) and body ground, and between the No. 26 terminal and body ground.
There should be 1 V or less.

Is the resistance as specified?

YES -Faulty left side impact sensor (first) or SRS unit; replace the left side
impact sensor (first) (see SIDE IMPACT SENSOR (FIRST)
REPLACEMENT). If the problem is still present, replace the SRS unit (see
SRS UNIT REPLACEMENT).

NO -Open in the floor wire harness; replace the floor wire harness.

DTC 44-1X ("X" CAN BE 0 THRU 9 OR A THRU F): NO SIGNAL FROM THE RIGHT SIDE
IMPACT SENSOR (FIRST)

Special Tools Required

SRS inflator simulator 07SAZ-TB4011A

SRS simulator lead L 070AZ-SNAA300

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

HDS).

2. Turn the ignition switch ON (II), then wait for 10 seconds.
3. Read the DTC (see CLEAR THE DTC MEMORY WITH THE HDS).

Is DTC 44-11 indicated?

YES -Go to step 5.

NO -Go to step 4.

4. Read the DTC.

NOTE:

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

Is DTC 44-12 indicated?

YES -Faulty right side impact sensor (first); replace the right side impact
sensor (first) (see SIDE IMPACT SENSOR (FIRST) REPLACEMENT).

NO -Intermittent failure, system is OK at this time. Go to
TROUBLESHOOTING INTERMITTENT FAILURES. If DTC 44-1x
except DTC 44-11 and 44-12 is indicated, faulty right side impact sensor
(first). Replace the right side impact sensor (first) (see SIDE IMPACT
SENSOR (FIRST) REPLACEMENT).

5. Turn the ignition switch OFF.
6. Disconnect the negative cable from the battery, then wait for 3 minutes.
7. Disconnect both seat belt tensioner connectors (see step 7 DISCONNECTING

SYSTEM CONNECTORS) and both seat belt buckle tensioner connectors
(see step 8 DISCONNECTING SYSTEM CONNECTORS ).

8. Disconnect the floor wire harness 4P connector (A) from the right side impact

sensor (first).

9. Disconnect SRS unit connector B (28P) from the SRS unit (see step 9

DISCONNECTING SYSTEM CONNECTORS).

10. Measure the resistance between the No. 27 and No. 28 terminals of SRS unit

connector B (28P). There should be an open circuit or at least 1 M ohms.
