Some SRS system connectors have a spring-loaded
lock.
To release the lock, pull the spring-loaded sleeve (A)
toward the stop (B) while holding the opposite half of
the connector. Then pull the connector halves apart. Be
sure to pull on the sleeve and not on the connector.
To reconnect, hold the pawl-side connector, and press
on the back of the sleeve-side connector in the direction
shown. As the two connector halves are pressed
together, the sleeve (A) is pushed back by the pawl (B).
Do not touch the sleeve. To release the lock, pull the spring-loaded sleeve (A)
toward the stop (B) while holding the opposite half of
the connector. Then pull the connector halves apart. Be
sure to pull on the sleeve and not on the connector half.
Hold both connector halves, and press them firmly
together until the projection (A) of the sleeve-side
connector cli

DTC (Diagnostic Trouble Codes) Reading the DTC
Precautions
24-22SRS
General Troubleshooting Information
A
The self-diagnostic function of the SRS system allows it
to locate the causes of system problems and store this
information in memory. For easier troubleshooting, this
data can be retrieved via a data link circuit.
 When you turn the ignition switch to ON (II), the SRS indicator comes on. If it goes off after 6 seconds, the
system is normal, and is not currently detecting any
abnormality.
 If there is an abnormality, the system locates and defines the problem, stores this information in
memory, and turns on the SRS indicator. The data
remains in memory even if the ignition switch is
turned off or the battery is disconnected.
 The data is stored in memory as a diagnostic trouble code (DTC).
 The ‘‘x’’ at the end of each DTC denotes a numeric character (0 thru 9) or an alpha character (A thru F)
that is displayed on the HDS.
 DTCs are either latching or resetting depending on the malfunction. With resetting DTCs, the SRS
indicator goes off the next time the ignition switch is
turned to ON (II), and the system is normal, but the
DTC is still stored. With latching DTCs, the SRS
indicator does not turn to LOCK (0) until the
malfunction is repaired and the DTC is cleared.
 When you connect the HDS to the data link connector (DLC), you can retrieve a more detailed DTC in the
HDS ‘‘SRS’’ menu.
NOTE: Only read DTCs from the SRS menu, not from
the SWS menus. SWS (ODS unit) DTCs are subcodes
of SRS unit DTCs. Only troubleshoot the
corresponding SRS DTCs.
 After reading and recording the DTC, proceed with the troubleshooting procedure for that code.
 Use only a digital multimeter to check the system. Make sure its output is 10 mA (0.01 A) or less when
switched to the smallest value in the ohmmeter range.
A tester with a higher output could damage the
airbag circuit or cause accidental airbag deployment
and possible injury.  Whenever the ignition switch is in ON (II), or has been
turned to LOCK (0), for less than 3 minutes, be careful
not to bump the SRS unit; the airbags could
accidentally deploy and cause damage or injuries.
 Before removing the dashboard wire harness, floor wire harness, disconnect the driver’s airbag
connector, the front passenger’s airbag connector,
both side airbag connectors, both side curtain airbag
connectors and both seat belt tensioner connectors.
 Make sure the battery is fully charged. If the battery is dead or low, electrical measurements may not be
correct.
 Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect
the SRS unit terminals or the sensor terminals with a
jumper wire. Use only the backprobe set and the
multimeter. Backprobe spring-loaded lock type
connectors correctly.
1. Make sure the ignition switch is in LOCK (0).
2. Connect the HDS to the data link connector (DLC) (A).
3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate,
troubleshoot the DLC circuit (see page 11-204).

NOTE: Make sure the battery is fully charged before
you begin.
To clear the DTCs from the SRS unit, use the HDS or the
following procedure. 1. Make sure the ignition switch is in LOCK (0).
2. Connect the SCS service connector (A) to the yellow MES 2P connector (B). Do not use a jumper
wire.
3. Turn the ignition switch to ON (II).
4. The SRS indicator will come on for about 6 seconds, and then go off. Remove the SCS service connector
from the MES connector (2P) within 4 seconds after
the indicator goes off.
5. The SRS indicator will come on again. Reconnect the SCS service connector to the MES connector
(2P) within 4 seconds after the indicator comes on.
6. When the SRS indicator goes off, remove the SCS service connector from the MES connector (2P)
within 4 seconds.
7. The SRS indicator blinks two times, indicating that the memory has been cleared.
8. Turn the ignition switch to LOCK (0).
9. Turn the ignition switch to ON (II) again. If the SRS indicator comes on for 6 seconds, and then goes off,
the system is OK. If the indicator stays on,
troubleshoot the DTC, refer to symptom
troubleshooting. If there was a malfunction, but it does not recur, it will
be stored in the memory as an intermittent failure, and
the SRS indicator may come on depending on this
malfunction detected.
NOTE:
 Check the condition of the battery (see page 22-67) and the charging system (see page 4-23). Low battery
voltage may cause some intermittent failures.
 A faulty or damaged cable reel can cause intermittent problems related to the driver’s airbag inflator DTCs.
After checking the DTC, troubleshoot as follows: 1. Make sure the ignition switch is in LOCK (0).
2. Connect the HDS to the data link connector (DLC).
3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate,
troubleshoot the DLC circuit (see page 11-204).
5. In the SRS MENU on the HDS, select SRS, then DTC to clear DTCs.
6. Read the DTC (see ‘‘Reading the DTC’’).
7. Clear the DTC memory(see ‘‘Clear the DTC’’).
8. Set the parking brake, then start the engine, and let it idle.
9. The SRS indicator comes on for about 6 seconds and then goes off.

Checking Front Passenger’s Weight Sensors
After a Vehicle Collision

A
10. Shake the related wire harnesses and theconnectors, and look for loose connections, poor
pinfits, and poor grounds.
11. Take a test-drive (quick acceleration, quick braking, and cornering), turn the steering wheel fully left
and right, and hold it there for 5 to 10 seconds. If
the problem recurs, the SRS indicator will come on.
12. If you cannot duplicate the concern, ask the client about the conditions when it occurred, or ask the
client to demonstrate the concern.
13. If you cannot duplicate the intermittent failure, the system is OK at this time. 1. Position the front passenger’s seat to the rearmost
position, adjust the seat-back to the forwardmost
position. Do not move it from this position.
2. Drive the vehicle, accelerate to 20 mph (36 km/h), then stop on level ground.
3. Make sure the ignition switch is in LOCK (0).
4. Connect the HDS to the data link connector (DLC) (A).
5. Turn the ignition switch to ON (II).
6. Make sure the HDS communicates with the vehicle and the SRS unit. If does not communicate,
troubleshoot the DLC circuit (see page 11-204).
7. From the SRS inspection menu, select Seat Weight Sensor, then Misc test, then SEAT OUTPUT CHK
and follow the prompts until the front passenger’s
weight sensor operation check is complete.

ODS Unit Initialization
A
When a seat-back cover, seat-back cushion, and/or ODS
unit is replaced, initialize the ODS by following the
procedure.
NOTE: A new (uninitialized) ODS unit installed with a
faulty OPDS sensor can cause DTC 85-71.
1. Clear the DTC memory (see page 24-23).
2. Make sure the front passenger’s seat is dry. Set the seat-back in a normal position, and make sure there
is nothing on the seat.
3. Make sure the ignition switch is in LOCK (0) and the MES connector is not shorted.
4. Connect the HDS to the data link connector (DLC) (A). 5. Turn the ignition switch to ON (II).
6. Make sure the HDS communicates with the vehicle
and the SRS unit. If it does not communicate,
troubleshoot the DLC circuit (see page 11-204).
7. From the HDS Main Menu, select SRS, then SRS, then Calibration. In the Calibration Menu, select
ODS INITIALIZATION. Follow the screen prompts to
initialize the ODS unit.
8. Turn the ignition switch to LOCK (0).
9. Disconnect the HDS from the DLC. NOTE: If the ODS unit fails to initialize after several
attempts, replace the OPDS sensor/seat-back and
retry. If the ODS unit continues to fail to initialize,
replace the ODS unit (see page 24-209).
