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 KOS-ECU
<vehicles with KOS> or WCM <vehicles with WCM>
diagnostic trouble code.
Check again if the DTC is set to the KOS-ECU <vehicles with
KOS> or WCM <vehicles with WCM>.
Q: Is the DTC set?
YES : Troubleshoot the KOS or WCM (Refer to GROUP
42B, Diagnosis
<KOS> or GROUP 42C,
<WCM>).
NO : Go to Step 3.
STEP 3. Recheck for diagnostic trouble code.
Check again if the DTC is set to the CAN box unit.
(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 CAN box unit.
NO : The trouble can be an intermittent malfunction (Refer
to GROUP 00, How to use

DTC U0195: Satellite radio CAN timeout
CAUTION
• If DTC U0195 is set, be sure to diagnose the
CAN bus line.
• When replacing the ECU, always check that
the communication circuit is normal. (Check
that the voltage is 10 V or more.)
.
DIAGNOSTIC FUNCTION
When the signals from satellite radio tuner cannot be
received, the CAN box unit sets DTC U0195.
.
JUDGMENT CRITERIA
With the ignition switch in the ON position, system
voltage between 10
− 16 volts (data from
ETACS-ECU), power supply fuse is OK, or odometer
value is 80.5 km (50 miles) or more, and the commu-
nications with satellite radio tuner cannot be estab-
lished for 2,500 ms or more, the CAN box unit
determines that a problem has occurred.
.
TROUBLESHOOTING HINTS
• The CAN bus line may be defective.
• The CAN box unit may be defective.
• The satellite radio tuner may be defective.
DIAGNOSIS
Required Special Tools:
• MB991958 Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: V.C.I.
• MB991827 M.U.T.-III USB Cable
• MB991910 M.U.T.-III Main Harness A
STEP 1. Using scan tool MB991958, diagnose the CAN bus
line

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

STEP 2. Using scan tool MB991958 read the satellite radio
tuner diagnostic trouble code.
Check whether a satellite radio tuner DTC are set or not.
Q: Is the DTC set?
YES : Diagnose the satellite radio tuner. (Refer to
).
NO : Go to Step 3.
STEP 3. Recheck for diagnostic trouble code.
Check again if the DTC is set to the CAN box unit.
(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.

DTC U0197: Hands free module CAN timeout
CAUTION
• If DTC U0197 is set, be sure to diagnose the
CAN bus line.
• When replacing the ECU, always check that
the communication circuit is normal. (Check
that the voltage is 10 V or more.)
.
DIAGNOSTIC FUNCTION
When the signals from hands free module cannot be
received, the CAN box unit sets DTC U0197.
.
JUDGMENT CRITERIA
With the ignition switch in the ON position, system
voltage between 10
− 16 volts (data from
ETACS-ECU), power supply fuse is OK, or odometer
value is 80.5 km (50 miles) or more, and the commu-
nications with hands free module cannot be estab-
lished for 2,500 ms or more, the CAN box unit
determines that a problem has occurred.
.
TROUBLESHOOTING HINTS
• The CAN bus line may be defective.
• The CAN box unit may be defective.
• The hands free module may be defective.
