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 41-2x, 41-3x, or 41-Bx indicated?

YES -Replace the left front impact sensor (see FRONT IMPACT SENSOR REPLACEMENT ). If the
DTC returns, replace the SRS unit (see SRS UNIT REPLACEMENT ).

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.

DTC 42-2X, 42-3X, 42-BX ("X" CAN BE 0 THRU 9 OR A THRU F): INTERNAL FAILURE OF THE
RIGHT FRONT IMPACT SENSOR

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 42-2x, 42-3x, or 42-Bx indicated?

YES -Replace the right front impact sensor (see FRONT IMPACT SENSOR REPLACEMENT ). If
the DTC returns, replace the SRS unit (see SRS UNIT REPLACEMENT ).

DTC 43-1X ("X" CAN BE 0 THRU 9 OR A THRU F): NO SIGNAL FROM THE LEFT SIDE IMPACT
SENSOR (FIRST)

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 43-1 x 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.

3. Turn the ignition switch OFF. Disconnect the negative cable from the battery, and wait for 3 minutes.

4. Check the connection between the floor wire harness 2P connector and the left side impact sensor (first).
