DTC Troubleshooting: 15-2

DTC 15-2:  Faulty Side Airbag Cutoff Indicator Circuit

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

2.Erase the DTC memory.

3.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?


YES - Turn the ignition switch OFF, go to 4.


NO - Intermittent failure, system is OK at this time. Go to Troubleshooting Intermittent Failures.


4.Turn the ignition switch ON (II), and check that the side airbag cutoff indicator comes on.

Does the side airbag cutoff indicator come on?


YES - Go to 5.


NO - Go to 6.


5.Make sure the side airbag cutoff indicator comes on for 5 seconds and then goes off.

Does the side airbag cutoff indicator go off?


YES - Faulty  OPDS unit or  SRS unit; replace the OPDS unit. If the problem is still present, replace the SRS unit.n


NO - Go to 35.


6.Turn the ignition switch OFF.

7.Check the No. 10 (7.5A) fuse in the under-dash fuse/relay box.

Is the fuse OK?


YES - Go to 8.


NO - Repair the short to ground in the No. 10 (7.5A) fuse circuit.n

8.Disconnect the O1o connector (1) from the OPDS unit (A).

 

9.Turn the ignition switch ON (II).

10.Check for voltage between the No. 3 terminal of the O1o connector and body ground. There should be battery voltage.

 

Is there battery voltage?


YES - Go to 11.


NO - Go to 23.

11.Turn the ignition switch OFF.

12.Disconnect the F3o connector (1) from the under-dash fuse/relay box (A).

 

13.Turn the ignition switch ON (II).

14.Check for voltage between the No. 3 terminal of the O1o connector and body ground. There should be 0.5 V or less.

 

Is the voltage as specified?


YES - Faulty  OPDS unit; replace the OPDS unit.n


NO - Go to 15.

15.Turn the ignition switch OFF.

16.Disconnect C2 connector (1) from the gauge assembly.

 

17.Turn the ignition switch ON (II).

18.Check for voltage between the No. 3 terminal of the O1o connector and body ground. There should be 0.5 V or less.

 

Is the voltage as specified?


YES - Short to power in the gauge assembly; replace the gauge assembly.n


NO - Go to 19.

19.Turn the ignition switch OFF.

20.Disconnect the C4 connector (1) from the C3 connector (2).

 

21.Turn the ignition switch ON (II).

22.Check for voltage between the No. 3 terminal of the O1o connector and body ground. There should be 0.5 V or less.

 

Is the voltage as specified?


YES - Short to power in the dashboard wire harness A; replace the dashboard wire harness A.n


NO - Short to power in the floor wire harness or in the OPDS unit harness; if the OPDS unit harness is OK, replace the floor wire harness.n

23.Turn the ignition switch OFF.

24.Backprobe the No. 8 terminal of C2 connector. Do not disconnect C2 connector from the gauge assembly.

25.Turn the ignition switch ON (II).

26.Check for voltage between the No. 20 terminal of C2 connector B and body ground. There should be battery voltage.

 

Is there battery voltage?


YES - Go to 27.


NO - Go to 31.


27.Turn the ignition switch OFF.

28.Disconnect the C4 connector (1) from the C3 connector (2).

 

29.Turn the ignition switch ON (II).

30.Check for voltage between the No. 18 terminal of the C4 connector and body ground. There should be battery voltage.

 

Is there battery voltage?


YES - Poor contact at the C4 and C3 connectors or an open in floor wire harness or in the OPDS unit harness. Check the connection between the C4 and C3 connectors; if the connection is OK, replace the faulty harness.n


NO - Poor contact at gauge assembly connector B (18P) or an open in dashboard wire harness A. Check C2 connector; if the connections are OK, replace dashboard wire harness A.n

31.Turn the ignition switch OFF.

32.Disconnect C2 connector (1) from the gauge assembly.

 

33.Turn the ignition switch ON (II).

34.Check for voltage between the No. 18 terminal of C2 connector and body ground. There should be battery voltage.

 

Is there battery voltage?


YES - Faulty side airbag cutoff indicator circuit; replace the gauge assembly.n


NO - Open in the dashboard wire harness; replace the dashboard wire harness.n

35.Turn the ignition switch OFF.

36.Disconnect the O1o connector (1) from the OPDS unit (A).

 


37.Turn the ignition switch ON (II).

Does the side airbag cutoff indicator come on?


YES - Go to 38.


NO - Faulty  OPDS unit; replace the OPDS unit.n


38.Turn the ignition switch OFF.

39.Disconnect C2 connector (1) from the gauge assembly.

 

40.Check resistance between the No. 20 terminal of C2 connector and body ground. There should 1 MW or more.

 

Is the resistance as specified?


YES - Short to ground in the side airbag cutoff indicator circuit; replace the gauge assembly.n


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