STEP 1. Using scan tool MB991958, diagnose the CAN bus
line.
Use scan tool MB991958 to diagnose the CAN bus lines.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to "ON" position.
(3) Diagnose the CAN bus line.
Q: Is the check result satisfactory?
YES : Go to Step 2.
NO : Repair the CAN bus lines (Refer to GROUP 54C,
Diagnosis-Can Bus Diagnostic Chart
completion, go Step 5.
STEP 2. Using scan tool MB991958, read the diagnostic
trouble code related to the other system.
Check if a DTC, which relates to CAN communication-linked
systems below, is set.
Powertrain control module
• DTC U1108: Combination meter time-out
ETACS-ECU
• DTC 014: Combination meter time-out
Q: Is the DTC set?
YES : Go to Step 3.
NO : Go to Step 4.
STEP 3. Recheck for diagnostic trouble code.
Recheck if the DTC is set.
1. Erase the DTC.
2. Turn the ignition switch to "ON" position.
3. Check if the DTC is set.
Q: Is the check result satisfactory?
YES : A poor connection, open circuit or other intermittent
malfunction is present in the CAN bus lines between
the combination meter and the multi-center display
unit (middle grade type) (Refer to GROUP 00, How to
Use Troubleshooting/Inspection Service Points-How
to Cope with Intermittent Malfunction
NO : Replace multi-center display unit (middle grade type)
and then go to step 5.

CAUTION
If DTC 019 is set in the ETACS-ECU, diagnose the
CAN main bus line.
CAUTION
Whenever the ECU is replaced, ensure that the
communication circuit is normal.
.
CIRCUIT OPERATION
The multi-center display unit (middle grade type) is
linked to CAN communication lines to communicate
with the combination meter and the powertrain con-
trol module, both of which have a terminator resistor.
.
DTC SET CONDITION
The multi-center display unit (middle grade type)
communicates with the ETACS-ECU via CAN bus
lines. If it can not receive all the necessary signals
from the ETACS-ECU, DTC 019 is set.
.
TECHNICAL DESCRIPTION (COMMENT)
Current trouble
• Connector(s) or wiring harness in the CAN bus
lines between the ETACS-ECU and the
multi-center display unit (middle grade type), the
power supply system to the display unit, the dis-
play unit itself, or the ETACS-ECU may be defec-
tive.
