Fig. 69: Measuring Resistance Between SRS Simulator Lead Terminals And Body Ground 

Is the resistance as specified?  

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

NO -Short to ground in dashboard wire harness B; replace dashboard wire harness B. 

DTC 21-1X ("X" CAN BE 0 THRU 9 OR A THRU F): OPEN IN DRIVER'S SEAT BELT 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 21-1x 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 

NOTE:

Before doing this troubleshooting procedure, review SRS Precautions and 
Procedures (see PRECAUTIONS AND PROCEDURES ) and General
