Is the resistance as specified?

YES — Faulty right side impact sensor (second) or SRS unit; replace the right side impact sensor
(second) (see SIDE IMPACT SENSOR (SECOND) REPLACEMENT ). If the problem is still
present, replace the SRS unit (see SRS UNIT REPLACEMENT ).

NO — Open in the right side wire harness or left side wire harness; replace the faulty harness.

DTC 46-CX («X» CAN BE 0 THRU 9 OR A THRU F): FAULTY POWER SUPPLY TO THE
RIGHT SIDE IMPACT SENSOR (SECOND)

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 46-Cx 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. Turn the ignition switch OFF. Disconnect the negative cable from the battery, then wait for 3 minutes.

4. Disconnect the right side wire harness 2P connector (A) from the right side impact sensor (second).

NOTE:

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

5. Disconnect SRS unit connector C (28P) from the SRS unit (see step 7 ).

6. Measure the resistance between the No. 19 terminal of SRS unit connector C (28P) and body ground.

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