SRS DTC Troubleshooting: 87-3x (x can be 0 thru 9 or A thru F)

DTC 87-3x ("x" can be 0 thru 9 or A thru F): Side Airbag Cutoff Indicator Stays On/Off

NOTE: Before doing this troubleshooting procedure, review SRS Precautions and Procedures, Technician Safety Information General Troubleshooting Information, Initial Inspection and Diagnostic Overview and Battery Terminal Disconnection and Reconnection. Procedures

1. Clear the DTC memory. Initial Inspection and Diagnostic Overview

2. Turn the ignition switch to 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?

4. Make sure nothing is on the front passenger's seat.

5. Disconnect ODS unit harness 18P connector (A) from the ODS unit.

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






7. Measure the voltage between ODS unit harness 18P connector terminal No. 18 and body ground. There should be battery voltage.

Is there battery voltage?
YES - Faulty ODS unit or gauge control module; replace the ODS unit, ODS Unit Replacement then clear the DTC. If the problem is still present, replace the gauge control module, Service and Repair then clear the DTC.

9. Remove the gauge control module. Service and Repair Disconnect the gauge control module connector (A) (36P) from the gauge control module.






10. Measure the resistance between ODS unit harness 18P connector terminal No. 18 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 A; replace the faulty harness, then clear the DTC.






11. Measure the resistance between ODS unit harness 18P connector terminal No. 18 and gauge control module 36P connector terminal No. 31. There should be less than 1.0 Ohms.

Is the resistance as specified?
YES - Replace the gauge control module, Service and Repair then clear the DTC.

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