9. Measure the resistance between body ground and

SRS unit connector A (28P) terminals No. 15 and
No. 27, individually. There should be an open
circuit or at least 1 M

Go to step 10.

Short to ground in the dashboard wire

harness or the engine compartment wire harness;
replace the faulty harness, then clear the DTC.

10. Reconnect the negative cable to the battery.

11. Turn the ignition switch to ON (II).

12. Measure the voltage between body ground and

SRS unit connector A (28P) terminals No. 15 and
No. 27, individually. There should be less than 0.2 V.

Go to step 13.

Short to power in the engine compartment

wire harness or the dashboard wire harness;
replace the faulty harness, then clear the DTC.

13. Turn the ignition switch to LOCK (0).

14. Connect the SRS inflator simulator (jumper

connector) and the black lead (A) of simulator
lead L to the engine compartment wire harness 2P
connector (B).

SRS UNIT CONNECTOR A (28P)

15. Measure the resistance between SRS unit

connector A (28P) terminals No. 15 and No. 27.
There should be less than 1.0

Faulty left front impact sensor or SRS unit;

replace the left front impact sensor (see page
24-210), then clear the DTC. If the problem is still
present, replace the SRS unit (see page 24-203).

Poor connection at C203, open in engine

compartment wire harness, or open in dashboard
wire harness. Inspect C203 (see page 22-22). If it is
OK, replace the faulty harness, then clear the
DTC.

• SRS inflator simulator 07SAZ-TB4011A
• SRS simulator lead L 070AZ-SNAA300

NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-13), General Troubleshooting Information (see page
24-22), and Battery Terminal Disconnection and
Reconnection (see page 22-68).

1. Clear the DTC memory (see page 24-23).

2. Turn the ignition switch to ON (II), and check that

the SRS indicator comes on for about 6 seconds
and then goes off.

Go to step 3.

Intermittent failure, system is OK at this time.

Go to Troubleshooting Intermittent Failures
(see page 24-24). If another DTC is indicated,
troubleshoot the DTC.

3. Turn the ignition switch to LOCK (0).

4. Disconnect the negative cable from the battery,

then wait at least 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 page 24-11), and at
connector C203 (see page 22-22).

Go to step 6.

Repair the poor connections, clear the DTC,

and retest. If DTC 42-1x is still present, go to step 6.

No Signal From the Right Front Impact
Sensor

Wire side of female terminals

Is the r esistance as specif ied?

Does the SRS indicator stay on, and is DT C 42-1x
indicated?

Ar e the connections OK ?

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 page 24-21).

8. Measure the resistance between SRS unit

connector A (28P) terminals No. 16 and No. 28.
There should be an open circuit or at least 1 M

Go to step 9.

Short in the engine compartment wire

harness or dashboard wire harness; replace the
faulty harness, then clear the DTC.
