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.

Ground

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.
