STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set to the radio and CD player.
(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 ETACS-ECU.

as a poor connection or open circuit in the CAN bus 
lines between the ETACS-ECU and the radio and CD 
player (Refer to GROUP 00, How to Cope with 
Intermittent Malfunction 

P.00-15

).

DTC U0151: SRS-ABG CAN timeout

CAUTION

• If DTC U0151 is set, be sure to diagnose the 

CAN bus line.

• When replacing the radio and CD player, 

always check that the communication circuit 
is normal.

.

DIAGNOSTIC FUNCTION

If the signal from SRS-ECU cannot be received, the 
radio and CD player sets DTC U0151.

.

JUDGMENT CRITERIA

With the ignition switch in the ON position, system 
voltage between 10

−16 volts (data from 

ETACS-ECU), power supply fuse(IOD fuse) is OK, or 
odometer value is 80.5 km (50 miles) or more, and 
the communication with SRS-ECU cannot be estab-
lished for 2,500 ms or more, the radio and CD player 
determines that a problem has occurred.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective

• The radio and CD player may be defective

• The SRS-ECU may be defective

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 (M.U.T.-III) 

P.54A-331

."

(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 SRS-ECU 
diagnostic trouble code
Check again if the DTC is set to the SRS-ECU.
Q: Is the DTC set?

YES : Troubleshoot the SRS (Refer to GROUP 52B, 

Troubleshooting 

P.52B-31

).

NO :  Go to Step 3.

STEP 3. Using scan tool MB991958, read the A/C-ECU 
diagnostic trouble code.
Check if the DTC U0151 is set to the A/C-ECU.
Q: Is the DTC set?

YES : Go to Step 4.
NO :  Go to Step 5.

DTC U0154: OCM (occupant classification-ECU) CAN timeout

CAUTION

If DTC U0154 is set, be sure to diagnose the CAN 
bus line.

CAUTION

When replacing the radio and CD player, always 
check that the communication circuit is normal.

.

DIAGNOSTIC FUNCTION

When the signals from occupant classification-ECU 
cannot be received, the radio and CD player sets 
DTC U0154.

.

JUDGMENT CRITERIA

With the ignition switch in the ON position, system 
voltage between 10 

− 16 volts (data from 

ETACS-ECU), power supply fuse(IOD fuse) is OK, or 
odometer value is 80.5 km (50 miles) or more, and 
the communications with occupant classifica-
tion-ECU cannot be established for 2,500 ms or 
more, the radio and CD player determines that a 
problem has occurred.

.

TROUBLESHOOTING HINTS

• The CAN bus line may be defective.

• The radio and CD player may be defective.

• The occupant classification-ECU may be defec-

tive.
