DTC 86-1X, 86-2X ("X" CAN BE 0 THRU 9 OR A THRU F): FAULTY OPDS 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 DTC 86-1x or 86-2x indicated?

YES -Go to step 3.

NO -Intermittent failure, system is OK at this time. Go to
TROUBLESHOOTING INTERMITTENT FAILURES. If another DTC is
indicated, troubleshoot the DTC.

NOTE:

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

NOTE:

After market 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 86-1x or 86-2x. If one of these
devices was used, clear the DTC, operate the device
near the seat-back, and recheck for DTCs. If DTC 86-1x
or 86-2x is set, clear it, and do not use the device near
the seat-back.
