STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set to the satellite radio tuner.
(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 WCM or KOS-ECU.
NO :  The trouble can be an intermittent malfunction such 

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

P.00-15

).

STEP 5. Recheck for diagnostic trouble code.
Check again if the DTC is set to the satellite radio tuner.
(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 satellite radio tuner.
NO :  The trouble can be an intermittent malfunction such 

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

DTC U0184: Audio CAN timeout

CAUTION

• If DTC U0184 is set to the satellite radio tuner, 

always diagnose the CAN bus line.

• Before replacing the satellite radio tuner, 

ensure that the communication circuit is nor-
mal.

.

TROUBLE JUDGMENT

If the signal from radio and CD player cannot be 
received, the satellite radio tuner sets DTC U0184.

.

JUDGMENT CRITERIA

After the following statuses continue to be true for 5 
seconds, if the communication with the radio and CD 
player cannot be established for 0.6 second or more, 
the satellite radio tuner determines that a problem 
has occurred.

• No abnormality is present to the network.

• Ignition switch is in the ON position.

• No abnormality is present to the power supply 

fuse (IOD fuse), or the odometer value is at 80.5 
km (50.0 miles) or more.

• ETACS-ECU system voltage is at 10−16 volts.

.

TROUBLESHOOTING HINTS

• The radio and CD player may be defective.

• The satellite radio tuner may be defective.

• The CAN bus may be defective.

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 

Scan Tool (M.U.T.-III) 

P.54A-655

."

(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 radio and CD 
player diagnostic trouble code.
Check if DTC is set to the radio and CD player.
Q: Is the DTC set?

YES : Troubleshoot the radio and CD player (Refer to 

P.54A-333

).

NO :  Go to Step 3.

STEP 3. Using scan tool MB991958, read the ETACS 
diagnostic trouble code.
Check if the DTC U0184 is set to the ETACS-ECU.
Q: Is the DTC set?

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