29. Turn the ignition switch ON (II).

30. Check for voltage between the No. 3 terminal of the

right side wire harness 4P connector C861 and
body ground. There should be battery voltage.

Poor contact at the right side wire harness 4P

and OPDS unit harness 4P connectors or an open in
the OPDS unit harness. Check the connection
between the right side wire harness and OPDS unit
harness 4P connectors; if the connection is OK,
replace the OPDS unit harness.

Poor contact at gauge assembly connector

A (14P) or an open in the dashboard wire harness
or right side wire harness. Check gauge assembly
connector A (14P); if the connections are OK,
replace the faulty harness.

31. Turn the ignition switch OFF.

32. Disconnect gauge assembly connector B (22P) from

the gauge assembly.

33. Turn the ignition switch ON (II).

34. Check for voltage between the No. 11 terminal of

gauge assembly connector B (22P) and body
ground. There should be battery voltage.

DTC 15-3:

YES

23-201

Faulty OPDS Sensor

1. Erase the DTC memory (see page 23-38).

2. Turn the ignition switch ON (II), and check that the

SRS indicator comes on for about 6 seconds and
then goes off.

Go to step 3.

Intermittent failure, system is OK at this time.

Go to Troubleshooting Intermittent Failures (see
page 23-39).

NOTE: Aftermarket devices (fluorescent lights,
laptop computers, etc.) used near the front
passenger’s seat-back can interfere with the seat-
back sensors and cause a false DTC 15-3. If one of
these devices was used, erase the DTC, operate the
device near the seat-back, and recheck for DTCs. If
DTC 15-3 is reset, erase it, and do not use the
device near the seat-back.

3. Check the connection at the OPDS sensor harness

connector and the OPDS unit connector.

Go to step 4.

Reconnect the OPDS sensor harness

connector, and clear the DTC.

4. Replace the OPDS sensor/seat back foam (see page

20-102), and reinitialize the OPDS (see page 23-40).

5. Erase the DTC memory, then check for DTC 15-3.

Go to step 6.

The system is OK.

6. Replace the OPDS unit (see page 23-387), and

reinitialize the OPDS.

7. Erase the DTC memory, then check for DTC 15-3.

Replace the SRS unit (see page 23-382).

The system is OK.

Does the SRS indicator stay on?

Ar e the connections OK ?

Is DT C 15-3 indicated?
