STEP 5. Resistance measurement at the C-27 SRS-ECU
connector.
(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-27 SRS-ECU connector.
DANGER
To prevent the air bag from deploying unintentionally,
disconnect the intermediate connector D-08 to short
the squib circuit.
(3) Disconnect the D-08 intermediate connector, unlock the
connector by sliding the locking button to the direction of the
arrow as shown in the figure, and then disconnect the
connector.
CAUTION
The short spring may not be released due to the insuffi-
cient insertion. Therefore, insert the insulator for 4 mm (0.6
inch) or more.
(4) Insert a cable tie [3 mm (0.12 inch) wide, 0.5 mm (0.02 inch)
thick] between terminal 39, 40 and the short spring to
release the short spring.

STEP 6. Short circuit check between the D-104 curtain air
bag module harness side connector and the D-08
intermediate harness.
(1) Disconnect the negative battery terminal.
DANGER
To prevent the air bag from deploying unintentionally,
disconnect the curtain air bag module connector
D-104 to short the squib circuit.
(2) Disconnect curtain air bag module (RH) D-104. 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.
(3) Disconnect the D-08 intermediate connector, unlock the
connector by sliding the locking button to the direction of the
arrow as shown in the figure, and then disconnect the
connector.
(4) Because the short spring is installed to the D-08
intermediate connector (curtain air bag harness side), insert
a cable tie [3 mm (0.12 inch) wide, 0.5 mm (0.02 inch) thick]
between terminals 1, 2 and the short spring to release the
short spring.
CAUTION
Do not insert a probe into the terminal from its front side
directly, as the connector contact pressure may be weak-
ened.
(5) Check for continuity between the D-08 intermediate
connector (curtain air bag harness side) terminal No. 1 and
No. 2.
It should be open circuit.
Q: Is it open circuit?
YES : Replace the curtain air bag module (RH) (Refer to
). Then go to Step 7.
NO : Repair the wiring harness.
