(b) Overlap the 2 stripped wire ends inside of the
pressure±contact sleeve as illustrated in the left.
HINT: The blue pressure±contact sleeve
(Part No. 82999±12020) is available individually.
HINT: You might find it easier if you use a miniature screwdriv-
er as a guide as you insert wires into the sleeve.
(c) The crimping tool (AMP Part No. 169060) has color marks on
it. Place the sleeve in the correct section of the tool according
to the color of the sleeve itself.
(d) With the center of the sleeve correctly placed between the
crimping jaws, squeeze the crimping tool until either end
comes into contact at the section marked by ºCLOSE HEREº.
HINT: Check to see that the sleeve and wires are still in the
correct position before closing the crimping tool ends with
steady pressure. RS±38

(e) Pull the joined wires to either end. Make sure that they are
joined firmly by the sleeve.
NOTICE: If the joined wires come loose the splice is de-
fective, so replace the sleeve and repeat the procedure.
(f) Crimp both ends of the sleeve with the crimping tool at the
ºINSº position.
3. PROTECT JOINED SECTION
Wrap silicon tape around the joins to protect them from water.
HINT:
wBefore starting the operation, thoroughly wipe dirt and
grease off the sections to be joined.
wIf the adhesive surfaces of 2 tapes come in contact, they
will stick together and will not come apart, so do not
remove the backing film except when using the tape.
wDo not let oil and dust, etc., get on the tape surface.
(a) Ready about 100 mm (3.94 in.) of silicon tape
(Part No. 08231±00045) and peel off the film.
(b) Stretch the silicon tape until its width is reduced by half.
(c) About 10 mm (0.39 in.) from the end of the pressure contact
sleeve, wrap the silicon tape around the sleeve 3 or more
times while stretching the tape.
(d) Wrap the remaining part of sleeve with half of the tape
overlapping at each turn.
(e) Firmly wrap the tape 2 times or more about 10 mm (0.39 in.)
from the other end of the pressure±contact sleeve, then wrap
the tape back towards the start again and firmly finish winding
the tape around the center of the sleeve.

(f) Fix the corrugated tube to the wire using silicon tape.
(g) After applying the silicon tape, apply vinyl tape on the
corrugated tube of repair wire side over to the corrugated
tube of vehicle wire harness side. RS±40

DIAGNOSIS INSPECTION
SRS warning light check
(a) Turn the ignition switch to ACC or ON and check that the SRS
warning light lights up.
(b) Check that the SRS warning light goes out after approx. 6
seconds.
HINT:
wWhen the ignition switch is at ACC or ON and the SRS
warning light remains on or flashes, the center airbag
sensor assembly has detected a malfunction code.
wIf, after approx. 6 seconds have elapsed, the SRS
warning light sometimes lights up or the SRS warning
light light up even when the ignition switch is OFF, a
short in the SRS warning light circuit can be considered
likely. Proceed to ºSRS warning light systemº on page
RS±97.
Diagnostic trouble code check
Using diagnosis check wire:
1. OUTPUT DIAGNOSTIC TROUBLE CODE
(a) Turn the ignition switch to ACC or ON position and wait
approx. 20 seconds.
(b) Using SST, connect terminals Tc and E
1 of the DLC1 or
DLC2.
SST 09843±18020
NOTICE: Never make a mistake with the terminal connec-
tion position as this will cause a malfunction. RS±44
± SUPPLEMENTAL RESTRAINT SYSTEMTROUBLESHOOTING
Page 1728 of 2543

2. READ DIAGNOSTIC TROUBLE CODE
Read the 2±digit diagnostic trouble code as indicated by the
number of times the SRS warning light blinks. As an example,
the blinking patterns, normal, 11 and 31 are as shown on the
illustration.
wNormal code indication
The light will blink 2 times per second.
wMalfunction code indication
The number represented by the first blinking code out-
put indicates the first digit of a 2±digit diagnostic trouble
output.
After a 1.5 second pause, the second blinking code will
indicate the second digit.
If there are 2 or more codes, there will be a 2.5 second
pause between each code. After all the codes have
been output, there will be a 4.0 second pause and they
will all be repeated.
HINT:
wIn the event of a number of trouble codes, indication will
start from the smallest numbered code.
wIf it does not output a diagnostic trouble code or outputs
a diagnostic trouble code without terminal connection,
proceed to the Tc terminal circuit inspection on page
RS±99.
Using TOYOTA hand±held tester:
(a) Hook up the TOYOTA hand±held tester to the DLC1 or DLC2.
(b) Read the diagnostic trouble codes by following the prompts
on the tester screen.
HINT: Please refer to the TOYOTA hand±held tester opera-
tor 's manual for further details.
