10. Turn the ignition switch OFF.  

11. Measure the resistance between the No. 10 terminal of e-pretensioner unit connector B (14P) and 

body ground, and between the No. 11 terminal of e-pretensioner unit connector B (14P) and body 
ground. There should be 0-1.0ohms.

Are the resistances as specified?  

YES - Go to step 12. 

NO - Open between the No. 10 terminal of e-pretensioner unit connector B (14P) and body ground, or 
between the No. 11 terminal of e-pretensioner unit connector B (14P) and body ground or poor 
connection at G653 (see RIGHT SIDE WIRE HARNESS (FRONT BRANCH) ). 

12. Measure the resistance between the No. 5 terminals of e-pretensioner unit connector A (5P) and body 

ground. There should be 0-1.0 ohms.

14. Disconnect SRS unit connect A (28P) from the SRS unit (see step 7 ).  

15. Measure the resistance between the No. 14 terminal of SRS unit connector A (28P) and body ground. 

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

Is the resistance as specified?  

YES - Go to step 16. 

NO - Short to ground between the No. 14 terminal of SRS unit connector A (28P) and the No. 6 
terminal of e-pretensioner unit connector B (14P). 

16. Measure the resistance between the No. 14 terminal of SRS unit connector A (28P) and the No. 6 

terminal of e-pretensioner unit connector B (14P). There should be 0-1.0 ohms.

NO - Open between the No. 14 terminal of SRS unit connector A (28P) and the No. 6 terminal of e-
pretensioner unit connector B (14P). 

DTC 81-61: NO SIGNAL FROM FRONT PASSENGER'S WEIGHT SENSOR UNIT; DTC 81-62: 
RESPONSE DATA ERROR FROM THE FRONT PASSENGER'S WEIGHT SENSOR UNIT 

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

2. Read the DTC (see GENERAL TROUBLESHOOTING INFORMATION ). 

Is DTC 81-61 or 81-62 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. Check the connection between the floor wire harness 6P connector and the front passenger's weight 

sensor unit (see FRONT PASSENGER'S WEIGHT SENSOR UNIT REPLACEMENT ). 

Is the connection OK?  

YES - Go to step 4. 

NO - Repair the poor connection and retest. If DTC 81-61 or 81-62 is still present, go to step 4. 

4. Turn the ignition switch OFF.  

5. Check the No. 10 (7.5 A) fuse in the driver's under-dash fuse/relay box. 

Is the fuse OK?  

YES - Go to step 6. 

NO - Replace the fuse, then turn the ignition switch ON (II). If the fuse blows again, check for a short 
in the No. 10 (7.5 A) fuse circuit (dashboard wire harness A or right side wire harness). 

6. Disconnect the right side wire harness 6R connector (A) from the front passenger's weight sensor unit. 

NOTE:

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