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.

).
STEP 2. Using scan tool MB991958 read the satellite radio
tuner diagnostic trouble code.
Check whether a satellite radio tuner DTCs are set or not.
(1) Turn the ignition switch to the "ON" position.
(2) Check for satellite radio tuner DTCs.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?
YES : Diagnose the satellite radio tuner. (Refer to
.)
NO : Go to Step 3.
STEP 3. Using scan tool MB991958, read the SRS-ECU
diagnostic trouble code.

STEP 4. 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 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 satellite radio tuner and the CAN
box unit (Refer to GROUP 00, How to Cope with
Intermittent Malfunction
).
STEP 5. 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 such
as a poor connection or open circuit in the CAN bus
lines between the satellite radio tuner and the CAN
box unit (Refer to GROUP 00, How to Cope with
Intermittent Malfunction
).
DTC U1415: Coding not completed/Data fail
CAUTION
• If DTC U1415 is set, be sure to diagnose the
CAN bus line.
• When replacing the CAN box unit, always
check that the communication circuit is nor-
mal. (Check that the voltage is 10 V or more.)
.
DIAGNOSTIC FUNCTION
If the vehicle information data is not registered to the
CAN box unit, the CAN box unit sets DTC U1415.
.
JUDGMENT CRITERIA
With the global coding counter value "0," if all the glo-
bal coding data (vehicle information) are not stored,
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 ETACS-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)
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 ETACS-ECU
diagnostic trouble code.
Check if the diagnostic trouble code relating to the coding error
is set to the ETACS-ECU.
Q: Is the DTC set?
YES : Troubleshoot the ETACS-ECU (Refer to
),
and then go to Step 3.
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 U1417: Implausible coding data
CAUTION
• If diagnostic trouble code U1417 is set in CAN
box unit, always diagnose the CAN bus lines.
If there is any fault in the CAN bus lines, an
incorrect diagnostic trouble code may be set.
In this case, the set diagnostic trouble code is
not highly reliable.
• Before replacing the CAN box unit, ensure
that the communication circuit is normal.
(Check that the voltage is 10 V or more.)
• When the diagnostic trouble code U1417 is
set in CAN box unit, the diagnostic trouble
code may also be set in ETACS-ECU. When
the diagnostic trouble code is set in
ETACS-ECU, carry out the diagnosis of the
diagnostic trouble code for ETACS-ECU first.
.
CIRCUIT OPERATION
CAN box unit receives the vehicle information stored
in the ETACS-ECU via CAN bus lines.
.
DTC SET CONDITIONS
CAN box unit communicates with ETACS-ECU via
CAN bus lines. This diagnostic trouble code is set
when the vehicle information received from the
ETACS-ECU is invalid.
.
PROBABLE CAUSES
• Malfunction of ETACS-ECU
• ETACS-ECUs have been interchanged between
two vehicles.
• CAN box unit malfunction
• External noise interference
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
