Is the resistance as specified?  

YES - Go to step 9. 

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

9. Reconnect the negative cable to the battery.  

10. Turn the ignition switch ON (II).  

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

and between the No. 16 terminal and body ground. There should be 1 V or less.

Is the resistance as specified?  

YES - Faulty right side impact sensor (first) or SRS unit; replace the right 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 right side wire harness; replace the right side wire harness.

RIGHT SIDE IMPACT SENSOR (FIRST)

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 44-Cx 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. Disconnect the negative cable from the battery, then wait for 3 minutes. 

4. Disconnect the right side wire harness 2P connector (A) from the right side impact sensor (first).

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

6. Measure the resistance between the No. 15 terminal of SRS unit connector C (28P) and body ground. 

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

NOTE:

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