DTC 71-2x (‘‘x’’ can be 0 thru 9 or A thru F):

24-145

SRS UNIT CONNECTOR B (28P)

10. Disconnect SRS unit connector B (28P) from the

SRS unit (see step 9 on page 24-21).

11. Measure the resistance between SRS unit

connector B (28P) terminals No. 5 and No. 6. There
should be less than 1.0

Faulty driver’s seat position sensor or SRS

unit; replace the driver’s seat position sensor
(see page 24-211), then clear the DTC. If the
problem is still present, replace the SRS unit
(see page 24-203).

Open in the floor wire harness, driver’s seat

wire harness (with seat heater) or the seat position
sensor harness; replace the faulty harness, then
clear the DTC.

NOTE: Before doing this troubleshooting procedure,
review SRS Precautions and Procedures (see page
24-13), General Troubleshooting Information (see page
24-22), and Battery Terminal Disconnection and
Reconnection (see page 22-68).

1. Clear the DTC memory (see page 24-23).

2. Turn the ignition switch to 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 24-24). If another DTC is indicated,
troubleshoot the DTC.

3. Turn the ignition switch to LOCK (0). Disconnect the

negative cable from the battery, then wait at least 3
minutes.

4. Disconnect the driver’s seat position sensor

harness 2P connector from the driver’s seat
position sensor (A) (see page 24-11).

5. Reconnect the negative cable to the battery.

6. Clear the DTC memory.

7. Read the DTC (see page 24-22).

Go to step 8.

Faulty driver’s seat position sensor; replace

the driver’s seat position sensor (see page 24-211),
then clear the DTC.

8. Turn the ignition switch to LOCK (0). Disconnect the

negative cable from the battery, then wait at least 3
minutes.

9. Disconnect both seat belt buckle tensioner

connectors (see step 8 on page 24-21) and both
seat belt tensioner connectors (see step 7 on page
24-21).

10. Disconnect SRS unit connector B (28P) from the

SRS unit (see step 9 on page 24-21).

11. Measure the resistance between SRS unit

connector B (28P) terminals No. 5 and No. 6. There
should be an open circuit or at least 1 M

Go to step 12.

Short in the floor wire harness, driver’s seat

wire harness (with seat heater), or the seat position
sensor harness; replace the faulty harness, then
clear the DTC.

12. Measure the resistance between body ground and

SRS unit connector B (28P) terminals No. 5 and
No. 6, individually. There should be an open circuit
or at least 1 M

Faulty driver’s seat position sensor, or the

SRS unit; replace the driver’s seat position sensor
(see page 24-211), then clear the DTC. If the
problem is still present, replace the SRS unit
(see page 24-203).

Short in the floor wire harness, driver’s seat

wire harness (with seat heater) or the seat position
sensor harness; replace the faulty harness, then
clear the DTC.

the ODS Unit

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

2. Clear the DTC memory (see page 24-23).

3. Read the DTC (see page 24-22).

Go to step 4.

Intermittent failure, system is OK at this time.

Go to Troubleshooting Intermittent Failures
(see page 24-24). If another DTC is indicated,
troubleshoot the DTC.

4. Check the connection between the ODS unit

harness 18P connector and the ODS unit.

Go to step 6.

Repair the poor connection, clear the DTC,

and retest. If DTC 85-61 or 85-62 is still present, go
to step 5.

5. Turn the ignition switch to LOCK (0).

6. Check the No. 9 (7.5 A) fuse in the under-dash fuse/

relay box.

Go to step 7.

Replace the fuse, then turn the ignition switch

to ON (II). If the fuse blows again, check for a short
in the No. 9 (7.5 A) fuse circuit (floor wire harness,
front passenger’s seat wire harness (with seat
heater), or ODS unit harness).

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

from the ODS unit.

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

9. Measure the voltage between ODS unit harness

18P connector terminal No. 1 and body ground.
There should be battery voltage.

Go to step 10.

Open in the floor wire harness, front

passenger’s seat wire harness (with seat heater) or
ODS unit harness; replace the faulty harness, then
clear the DTC.
