DTC 87-31

DTC 87-31, 87-32: Side Airbag Cutoff Indicator Stays On/Off

NOTE: Before doing this troubleshooting procedure, review SRS Precautions and Procedures and General Troubleshooting Information.

1. Clear the DTC memory.
2. Turn the ignition switch ON (II), and check that the side airbag cutoff indicator comes on for about 6 seconds and then goes off.

Does the side airbag cutoff indicator go off and stay off?

YES - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures. Troubleshooting Intermittent Failures If another DTC is indicated, troubleshoot the DTC.

NO - Check the No. 3 (10 A) fuse in the under-dash fuse/relay box, then go to step 3.

3. Check the No. 3 (10 A) fuse in the under-dash fuse/relay box

Is the fuse OK?

YES - Go to step 4.

NO - Replace the fuse, then turn the ignition switch ON (II). If the fuse blows again, check for a short in the No. 3 (10 A) fuse circuit (dashboard wire harness).

4. Turn the ignition switch OFF. Make sure nothing is on the front passenger's seat.
5. Disconnect the ODS unit harness 18P connector (A) from the ODS unit.






6. Turn the ignition switch ON (II).
7. Measure the voltage between the No. 18 terminal of the ODS unit 18P connector and body ground. There should be battery voltage.






Is there battery voltage?

YES - Faulty ODS unit or gauge control module; replace the ODS unit. If the problem is still present, replace the gauge control module.

NO - Go to step 7.

8. Turn the ignition switch OFF.
9. Disconnect gauge control module connector C (40P) from the gauge control module.






10. Measure the resistance between the No. 18 terminal of the ODS unit 18P connector and body ground. There should be an open circuit or at least 1 Mohms.






Is the resistance as specified?

YES - Go to step 10.

NO - Short to ground in the ODS unit harness, floor wire harness, or dashboard wire harness; replace the faulty harness.

11. Measure the resistance between the No. 18 terminal of the ODS unit 18P connector and the No. 32 terminal of gauge control module C (40P). There should be 0 - 1.0 ohm.






Is the resistance as specified?

YES - Replace the gauge control module.

NO - Open in the ODS unit harness, floor wire harness, or dashboard wire harness; replace the faulty harness.
