STEP 3. Check SRS-ECU connector E-07 and driver’s seat
belt pre-tensioner connector F-27. (Using scan tool
MB991958, read the diagnostic trouble code).
(1) Disconnect the negative battery terminal.
(2) Disconnection connectors E-07 and F-27, and then
reconnect them.
(3) Connect the negative battery terminal.
(4) Erase the diagnostic trouble code memory, and check the
diagnostic trouble code.
Q: Is DTC 26 set?
YES : Go to Step 4.
NO : The procedure is complete. (It is assumed that DTC
26 set as connector E-07 or F-27 was engaged
improperly).

STEP 4. Check the driver's seat belt pre-tensioner. (Using
scan tool MB991958, read the diagnostic trouble code).
(1) Disconnect the negative battery terminal.
(2) Disconnect the driver's seat belt pretensioner connector
F-27.
(3) Connect special tool MB991865 to special tool MB991866.
CAUTION
Do not insert a test probe into the terminal from its front
side directly as the connector contact pressure may be
weakened.
(4) Insert special tool MB991866 into the harness connector by
backprobing.
(5) Connect the negative battery terminal.
(6) Erase diagnostic trouble code memory, and check the
diagnostic trouble code.
Q: Is DTC 26 set?
YES : Go to Step 5.
NO : Replace the driver's seat belt pre-tensioner (Refer to

STEP 5. Check the driver's side seat belt pretensioner
circuit at the SRS-ECU connector E-07.
(1) Disconnect SRS-ECU connector E-07.
(2) Disconnect driver's seat belt pretensioner connector F-27.
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.
(3) Insert a cable tie [3 mm (0.12 inch) wide, 0.5 mm (0.02 inch)
thick] between terminals 29, 30 and the short spring to
release the short spring.
CAUTION
Do not insert a test probe into the terminal from its front
side directly as the connector contact pressure may be
weakened.
(4) Check for continuity between E-07 harness connector
terminals 29 and 30.
It should be open circuit.
Q: Does continuity exist?
YES : Go to Step 6.
NO : Eras the diagnostic trouble code memory, and check
the diagnostic trouble code. If DTC 26 sets, replace
the SRS-ECU (Refer to
).

STEP 6. Check the harness for short circuit between
SRS-ECU connector E-07 (terminal No.29 and 30) and
driver’s seat belt pre-tensioner connector F-27 (terminal
No.1 and 2).
NOTE: After inspecting intermediate connector E-19, inspect
the wiring harness. If the intermediate connector E-19 is dam-
aged, repair or replace it (Refer to GROUP 00E, Harness Con-
nector Inspection
). Then go to Step 7.
Q: Are harness wires between SRS-ECU connector E-07
(terminal No.29 and 30) and driver’s seat belt
pre-tensioner connector F-27 (terminal No.1 and 2) in
good condition?
YES : Go to Step 7.
NO : Repair the harness wires between SRS-ECU
connector E-07 and driver’s side seat belt
pre-tensioner connector F-27. Then go to Step 7.
STEP 7. Recheck for diagnostic trouble code.
Q: Is DTC 26 set?
YES : Return to Step 1.
NO : The procedure is complete. (If no malfunctions are not
found in all steps, an intermittent malfunction is
suspected. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
− How to
Cope with Intermittent Malfunction
).
