the circuit inside the occupant classification-ECU.

.

TROUBLESHOOTING HINTS

Malfunction of the occupant classification-ECU

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicles 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 

scan tool 

P.52B-28

."

(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, 

Diagnosis 

P.54C-17

).

STEP 2. Recheck for diagnostic trouble code.
Check again if the DTC is set.
(1) Erase the DTC.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON" 

position.

(3) Check if DTC is set.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?

YES : Replace the passenger seat cushion frame assembly 

(Refer to GROUP 52A, Front Seat Assembly 

P.52A-17

).

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 

P.00-15

).

CAUTION

If DTC B210D, B210E is set in the occupant clas-
sification-ECU, always diagnose the CAN main 
bus lines.

.

TROUBLE JUDGMENT

The occupant classification-ECU sets DTC B210D if 
the power supply fuse voltage decreases to the 
specified value or less, and sets DTC B210E if the 
power supply fuse voltage increases to the specified 
value or more.

.

TECHNICAL DESCRIPTION (COMMENT)

The power supply fuse or the occupant classifica-
tion-ECU may have a problem.

.

TROUBLESHOOTING HINTS

• The power supply fuse may be defective.

• The occupant classification-ECU may be defec-

tive.

• The battery may be defective.

• The generator may be defective.

• The wiring harness or connectors may have 

loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector

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. Measure the voltage at the occupant 
classification-ECU connector.
(1) Disconnect the D-34-2 occupant classification-ECU 

connector.

(2) Measure the voltage between the D-34-2 harness side 

connector terminal No. 21 and the body ground.

• The voltage should measure 12 volts (battery positive 

voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : Go to Step 10.
NO :  Go to Step 2.

STEP 2. Power supply fuse No.17 check.
Q: Is the fuse in good condition?

YES : Go to Step 4.
NO :  Go to Step 3.

STEP 3. Wiring harness check between the C-315 
ETACS-ECU connector terminal No.4 and the D-34-2 
occupant classification-ECU connector terminal No. 21.

•  Short circuit check for SRS-ECU power supply wire

Q: Is the check result normal?

YES : Replace the power supply fuse.
NO :  Repair the wiring harness. And then replace the 

power supply fuse.
