STEP 4. Check the harness for open circuit between
SRS-ECU connector C-36 (terminal No.43 and 44) and the
passenger's seat belt pre-tensioner connector D-40
(terminal No.2 and 1).
(1) Disconnect the negative battery terminal.
(2) While pushing the part "A" indicated in the figure of the
harness side connector, turn the lock lever to the direction
of the arrow to release the lock lever, and disconnect the
C-36 SRS-ECU connector.
DANGER
To prevent the seat belt pre-tensioner from deploying
unintentionally, disconnect the passenger’s seat belt
pre-tensioner connector D-40 to short the squib cir-
cuit.
(3) Disconnect SRS-ECU connector C-36 and passenger's
seat belt pre-tensioner connector D-40. For connector D-40,
use a flat-tipped screwdriver to unlock the locking button at
the harness side connector by withdrawing it toward you in
two stages, and then disconnect the connector.
CAUTION
Insert an insulator such as a cable tie to a depth of 4mm
(0.16 inch) or more, otherwise the short spring will not be
released.
(4) Insert a cable tie [3 mm (0.12 inch) wide, 0.5 mm (0.02 inch)
thick] between terminals 43, 44 and the short spring to
release the short spring.
