STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set to the ETACS-ECU.
(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 radio and CD player or CD changer.
NO : The trouble can be an intermittent malfunction such
as a poor connection or open circuit in the CAN bus
lines between the radio and CD player or CD changer
and the ETACS-ECU (Refer to GROUP 00, How to
Cope with Intermittent Malfunction

DTC U0195: Satellite radio tuner CAN timeout
CAUTION
• If DTC U0195 is set to the ETACS-ECU, always
diagnose the CAN bus line.
• Before replacing the ECU, ensure that the
communication circuit is normal.
.
TROUBLE JUDGMENT
If the signal from satellite radio tuner cannot be
received, the ETACS-ECU sets DTC U0195.
.
JUDGMENT CRITERIA
After the following statuses continue to be true for 5
seconds, if the communication with the satellite radio
tuner cannot be established for 0.6 second or more,
the ETACS-ECU 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, 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 satellite radio tuner may be defective.
• The ETACS-ECU 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)
."
(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. Using scan tool MB991958, read the satellite radio
tuner diagnostic trouble code.
Check if DTC is set to the satellite radio tuner.
Q: Is the DTC set?
YES : Troubleshoot the satellite radio (Refer to
).
NO : Go to Step 3.
STEP 3. Using scan tool MB991958, read the SRS-ECU
diagnostic trouble code.
Check if the DTC U0195 is set to the SRS-ECU.
Q: Is the DTC set?
YES : Go to Step 4.
NO : Go to Step 5.

DTC U0197: Hands free module CAN timeout
CAUTION
• If DTC U0197 is set to the ETACS-ECU, always
diagnose the CAN bus line.
• Before replacing the ECU, ensure that the
communication circuit is normal.
.
TROUBLE JUDGMENT
If the signal from hands free module cannot be
received, the ETACS-ECU sets DTC U0197.
.
