HOW TO DIAGNOSE THE CAN BUS LINES

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)

1. Connect scan tool MB991958 to the data link connector.
2. Turn the ignition switch to the "ON" position.
3. Select "CAN bus diagnosis" from the start-up screen.
4. When the vehicle information is displayed, confirm that it

matches the vehicle being diagnosed.

• If they match, go to Step 8.

• If not, go to Step 5.

5. Select the "view vehicle information" button.
6. Enter the vehicle information and select the "OK" button.
7. When the vehicle information is displayed, confirm again

that it matches the vehicle being diagnosed.

• If they match, go to Step 8.

• If not, go to Step 5.

8. Select the "OK" button.
9. When the optional equipment screen is displayed, choose

the one which the vehicle is fitted with, and then select the
"OK" button.

CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using scan
tool MB991958.

When detecting fault and storing the diagnostic trou-
ble code, the ECU connected to CAN bus line
obtains the data before the determination of the diag-
nostic trouble code and the data when the diagnostic
trouble code is determined, and then stores the ECU
status of that time. By analyzing each data from scan
tool MB991958, the troubleshooting can be per-
formed more efficiently. The displayed items are as
the table below.

DIAGNOSTIC TROUBLE CODE CHART

M1544012900229

DIAGNOSTIC TROUBLE CODE PROCEDURES

DTC B2222: Radio receiver internal fail

CAUTION

If there is any problem in the CAN bus lines, an
incorrect diagnostic trouble code may be set.
Prior to this diagnosis, always diagnose the CAN
bus lines.

CAUTION

Before replacing the satellite radio tuner, be sure
to check that the power supply circuit, ground
circuit, and communication circuit are normal.

TROUBLE JUDGMENT

When the ignition switch is ON and the system volt-
age is from 10 V to 16 V (data from ETACS-ECU), if
the satellite radio tuner receives abnormal status by
signal conditioning 10 times consecutively, DTC
B2222 is stored.

COMMENTS ON TROUBLE SYMPTOM

The satellite radio tuner or CAN bus line may have a
problem.

PROBABLE CAUSES

• The satellite radio tuner may be defective.

• The CAN bus line may be defective
