Fig. 93: Measuring Resistance Between SRS Unit Connector B (28P) Terminal 7 And Body Ground

Is the resistance as specified?  

YES -Faulty SRS unit or poor connection at SRS unit connector B (28P) and the SRS unit. Check the 
connection; if the connection is OK, replace the SRS unit (see SRS UNIT REPLACEMENT ). 

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

DTC 28-1X ("X" CAN BE 0 THRU 9 OR A THRU F): OPEN IN FRONT PASSENGER'S SEAT BELT 
BUCKLE TENSIONER 

Special Tools Required  



SRS inflator simulator 07SAZ-TB4011A  



SRS simulator lead K 070AZ-SNAA200  

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 28-1x indicated?  

YES -Go to step 3. 

NO -Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures (see 
TROUBLESHOOTING INTERMITTENT FAILURES ). 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. 

NOTE:

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