Check again if the DTC is set.
(1)
Erase the DTC.
(2)
Turn the ignition switch to "ON" position.
(3)
Check if the DTC is set.
(4)
Turn the ignition switch to the "LOCK" (OFF) position.
Q:Is the DTC set?
YES:
Go to Step 3.
NO:
There is an intermittent malfunction such as poor
engaged connector(s) or open circuit (Refer to GROUP 00,
How to Use Troubleshooting/Inspection Service Points -
How to Cope with Intermittent Malfunctions P.00-15).
STEP 3. Check by dummy resistor connection. (Using scan
tool MB991958, read the diagnostic trouble code.)
(1)
Disconnect the negative battery terminal.
(2)
Disconnect the D-08 intermediate connector (connection
between curtain air bag harness and floor harness).

(3)
Connect special tool MB991865 to special tool MB991866.
Do not insert a probe into the terminal from its front side
directly, as the connector contact pressure may be
weakened.
(4)
Insert the probe of resistor harness, to which the dummy
resistor is installed, from the back of D-08 intermediate
connector (floor harness side).
(5)
Connect the negative battery terminal.
(6)
After erasing the diagnostic trouble code memory, check the
diagnostic trouble code again.
(7)
Disconnect the negative battery terminal.
Q:Is DTC B1B22 set?
YES:
Go to Step 4.
NO:
Go to Step 5.
STEP 4. Resistance measurement at the C-27 SRS-ECU
connector and the D-08 intermediate connector.
(1)
Disconnect the negative battery terminal.

Q:Does continuity exist?
YES:
Go to Step 6.
NO:
Repair the wiring harness between the C-27 harness
side connector terminal No. 39, 40 and the D-08
intermediate connector (floor harness side) terminal No.
2, 1.
STEP 5. Resistance measurement at the D-08 intermediate
connector terminal No. 1, 2 and the D-104 curtain air bag
module harness side connector terminal No. 1, 2.
(1)
Disconnect the negative battery terminal.
(2)
Disconnect the D-08 intermediate connector (connection
between curtain air bag harness and floor harness).
