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 B2-11 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 battery negative cable, and wait for 3 minutes.

4. Check the connections between the floor wire harness 2P connector and the rear safing sensor (see REAR

SAFING SENSOR REPLACEMENT ).

Is the connection OK?

YES -Go to step 5.

NO -Repair the poor connection and retest. If the DTC B2-11 is still present, go to step 5.

5. Disconnect the floor wire harness 2P connector (A) from the rear safing sensor.

NOTE:

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

6. Disconnect SRS unit connector C (28P) from the SRS unit (see step 9 on ).

7. Measure the resistance between the No. 5 and No. 6 terminals of SRS unit connector C (28P). There

should be an open circuit or at least 1Mohms.

Fig. 228: Measuring Resistance Between SRS Unit Connector C (28P) Terminal 5 And 6

Is the resistance as specified?

YES -Go to step 8.

NO -Short in the floor wire harness; replace the floor wire harness.

8. Measure the resistance between the No. 5 terminal of SRS unit connector C (28P) and body ground, and

between the No. 6 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 9.

NO -Short to ground in the floor wire harness; replace the floor wire harness.

9. Reconnect the battery negative cable.

10. Turn the ignition switch ON (II).

11. Measure the for voltage between the No. 5 terminal of SRS unit connector C (28P) and body ground, and

between the No. 6 terminal and body ground. There should be 1 V or less.

Is the voltage as specified?

YES -Go to step 12.

NO -Short to power in the floor wire harness; replace the floor wire harness.

12. Turn the ignition switch OFF.

13. Connect the SRS inflator simulator (jumper connector) and simulator lead L to the floor wire harness 2P

connector (A).

Connector

14. Measure the resistance between the No. 5 and No. 6 terminals of SRS unit connector C (28P). There

should be 0-1.0 ohms or less.

Fig. 232: Measuring Resistance Between SRS Unit Connector C (28P) Terminal 5 And 6

Is the resistance as specified?

YES -Faulty rear safing sensor or SRS unit; replace the rear safing sensor (see REAR SAFING
SENSOR REPLACEMENT ). If the problem is still present, replace the SRS unit (see SRS UNIT
REPLACEMENT ).

NO -Open in the floor wire harness; replace the floor wire harness.

DTC B2-17, B2-84, B2-90, B2-AX, B2-BX ("X" CAN BE 0 THRU 9 OR A THRU F): INTERNAL
FAILURE OF THE REAR SAFING SENSOR

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 B2-17, B2-84, B2-90, B2-Ax, or B2-Bx indicated?

YES -Replace the rear safing sensor (see REAR SAFING 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.
