Measure at the SRS-ECU connector C-41.
D Disconnect the SRS-ECU connector C-41.
D Disconnect the driver's seat belt pre-tensioner connector

D-28* and D-26
.
Caution
Disconnect the connector and short-circuit the squib
circuit before releasing the short bar of the SRS-ECU
connector in the following operation.
D Cable bands between terminals 29, 30 and the short bar
(width:3 mm, thickness:0.5 mm) between terminals 11 and
12 and the short bar, and release the short bar.
(See Figure A.)
Caution
As the short bar may not be releasable if inserted
insufficiently, insert more than 4 mm.
D Measure at the harness side
D Continuity check between terminals 29 and 30
Caution
Do not directly insert a probe or other devices at the
front of the connector to avoid a possible decrease in
the contact pressure.
OK: No continuity
Connector C-41
Replace the SRS-ECU.

D Connect the dummy resistor (MB991865) to the resistor harness
(MB991866).
D Disconnect the driver's seat belt pre-tensioner connector D-28*
*2
D-26 and connect to the resistor harness (MB991866) behind the
harness side connector.
Caution
Do not directly insert a probe or other devices at the front of the
connector to avoid a possible decrease in the contact pressure.
D Connect the negative (- ) terminal of the battery
D Check the diagnosis code again after erasing the memory.
Is code No.26 output?
Replace the driver's seat belt pre-tensioner.
NG
Check connector: D-28*
YES
Check the trouble
symptoms.
NG
Check the harness between the driver's seat belt
pre-tensioner and the SRS-ECU, and repair if necessary.
