SRS AIR BAG DIAGNOSIS

TSB Revision

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-335

STEP 5. 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 U0176 set?

YES : Replace the SRS-ECU (Refer to 

P.52B-436

). 

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

).

DTC U0184: Audio CAN Timeout

CAUTION

• If the DTC U0184 is set, be sure to diagnose 

the CAN main bus line.

• When replacing the ECU, always check that 

the communication circuit is normal.

.

DTC SET CONDITION

When the signals from radio and CD player or CD 
changer cannot be received, the SRS-ECU sets the 
DTC U0184.

.

JUDGMENT CRITERIA

Because of the CAN-B bus circuit malfunction, if 
SRS-ECU becomes unable to perform the normal 
data transmission, SRS-ECU determines that an 
abnormality is present.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective

• The radio and CD player or CD changer may be 

defective

• The SRS-ECU may be defective

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)

SRS AIR BAG DIAGNOSIS

TSB Revision

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-336

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. Using scan tool MB991958, read the audio 
diagnostic trouble code
Check if the DTC is set to the audio.
Q: Is the DTC set?

YES : Diagnose the radio and CD player (Refer to GROUP 

54A, Diagnosis 

P.54A-658

). Then go to Step 4.

NO :  Go to Step 3.

STEP 3. Using scan tool MB991958, read diagnostic 
trouble code No. U0184 for other system.
Check if the DTC U0184 is set in ETACS-ECU, occupant clas-
sification-ECU, combination meter, A/C-ECU, KOS-ECU or 
WCM, hands free module, satellite radio tuner.
Q: Is the DTC set?

YES : Replace the radio and CD player (Refer to GROUP 

54A, Radio and CD player 

P.54A-423

).

NO :  Go to Step 4.
