Honda Element. Manual - part 122

 

 

Fig. 139: Measuring Resistance Between SRS Unit Connector A (28P) Terminal 15 And 27 

Is the resistance as specified?  

YES -Faulty left front impact sensor or SRS unit-replace the left front impact sensor (see FRONT 
IMPACT SENSOR REPLACEMENT
 ). If the problem is still present, replace the SRS unit (see SRS 
UNIT REPLACEMENT
 ). 

NO -Poor connection at C402, open in engine compartment wire harness, or open in dashboard wire 
harness B. Inspect C402 (see ENGINE COMPARTMENT WIRE HARNESS (DASHBOARD) ). If it 
is OK, replace the faulty harness. 

DTC 42-1X ("X" CAN BE 0 THRU 9 OR A THRU F): NO SIGNAL FROM THE RIGHT FRONT 
IMPACT SENSOR 

Special Tools Required  

SRS inflator simulator 07SAZ-TB4011A  

SRS simulator lead H 07YAZ-S3AA100  

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 42-1x 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. 

NOTE:

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

3. Turn the ignition switch OFF.  

4. Disconnect the negative cable from the battery, and wait for 3 minutes.  

5. Check the connections between SRS unit connector A (28P) and the SRS unit, between the engine 

compartment wire harness 2P connector and the right front impact sensor (see COMPONENT 
LOCATION INDEX
 ), and at connector C402 (see ENGINE COMPARTMENT WIRE HARNESS 
(DASHBOARD)
 ). 

Are the connections OK?  

YES -Go to step 6. 

NO -Repair the poor connections and retest. If DTC 42-1x is still present, go to step 6. 

6. Disconnect the engine compartment wire harness 2P connector (A) from the right front impact sensor.

7. Disconnect SRS unit connector A (28P) from the SRS unit (see step 9 on ).  

8. Measure the resistance between the No. 16 and No. 28 terminals of SRS unit connector A (28P). There 

should be an open circuit or at least 1Mohms.

YES -Go to step 9. 

NO -Short in the engine compartment wire harness or dashboard wire harness B; replace the faulty 
harness. 

9. Measure the resistance between the No. 16 terminal of SRS unit connector A (28P) and body ground, and 

between the No. 28 terminal and body ground. There should be an open circuit or at least 1 Mohms.

Is the resistance as specified?  

YES -Go to step 10. 

NO -Short to ground in dashboard wire harness B or the engine compartment wire harness; replace the 
faulty harness. 

10. Reconnect the negative cable to the battery.  

11. Turn the ignition switch ON (II).  

12. Measure the voltage between the No. 16 terminal of SRS unit connector A (28P) and body ground, and 

between the No. 28 terminal and body ground. There should be 1 V or less.

Is the voltage as specified?  

YES -Go to step 13. 

NO -Short to power in the engine compartment wire harness or dashboard wire harness B; replace the 
faulty harness. 

13. Turn the ignition switch OFF.  

14. Connect the SRS inflator simulator (jumper connector) and simulator lead H to the engine compartment 

wire harness 2P connector (A).

15. Measure the resistance between the No. 16 and No. 28 terminals of SRS unit connector A (28P). There 

should be 0-1.0 ohms.
