STEP 8. Check the harness for open circuit between
SRS-ECU connector C-27 (terminal No.61 and 62) and the
ETACS-ECU connector C-313 (terminal No.4 and 2).
(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.
(3) Disconnect the ETACS-ECU connector C-313.
(4) Check for continuity between the following terminals. It
should be less than 2 ohms.
<Fuse No.12>
• SRS-ECU connector C-27 (terminal No.62) and the
ETACS-ECU connector C-313 (terminal No.2)
<Fuse No.18>
• SRS-ECU connector C-27 (terminal No.61) and the
ETACS-ECU connector C-313 (terminal No.4)
Q: Does continuity exist?
YES : Replace the ETACS-ECU (Refer to GROUP 54A,
ETACS-ECU
NO : Repair the harness wire between SRS-ECU
connector C-27 and the ETACS-ECU connector
C-313.
STEP 9. Recheck for diagnostic trouble code.
Check again if the DTC is set.
(1) Erase the DTC.
(2) Turn the ignition switch to the "ON" position.
(3) Check if the DTC is set.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC B212C <Fuse No.12 circuit> or B212D <Fuse
No.18 circuit> set?
YES : Replace the SRS-ECU (Refer to
).
NO : There is an intermittent malfunction such as poor
engaged connector(s) or open circuit (Refer to
GROUP 00, How to Cope with Intermittent
Malfunction
).

CAUTION
If DTCs are set in the SRS-ECU, always diagnose
the CAN main bus line.
.
DTC SET CONDITION
The above DTC is set if an abnormality is detected in the circuit
inside the SRS-ECU.
.
TROUBLESHOOTING HINTS
Malfunction of the SRS-ECU
DIAGNOSIS
Required Special Tools:
• MB991958: Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827: M.U.T.-III USB Cable
• MB991910: M.U.T.-III Main Harness A (Vehicles with
CAN communication system)
STEP 1. Using scan tool MB991958, diagnose the CAN bus
line
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect the
."
(2) Turn the ignition switch to the "ON" position.
(3) Diagnose the CAN bus line.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?
YES : Go to Step 2.
NO : Repair the CAN bus line (Refer to GROUP 54C,
).

STEP 2. Recheck for diagnostic trouble code.
Check again if the DTC is set.
(1) Turn the ignition switch to the "ON" position.
(2) Check if the DTC is set.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Are any "Stored" or "Active" DTCs set?

Malfunction
).
DTC B223D: OCM (occupant classification-ECU) DTC Present
CAUTION
If DTC B223D is set in the SRS-ECU, always diag-
nose the CAN main bus line.
.
DTC SET CONDITION
It is set if a DTC occurs in the occupant classifica-
tion-ECU.
.
TROUBLESHOOTING HINTS
