DIAGNOSTIC TROUBLE CODE PROCEDURES
TSB Revision
SIMPLIFIED WIRING SYSTEM (SWS)
54B-52
DTC 015: Multi center Display Unit (Middle Grade Type) Time-out.
CAUTION
DTC 015 may also be set on vehicles with the
multi center display (low-grade type). This is
because the display unit does not communicate
through the CAN bus lines, and there is no fault.
CAUTION
If DTC 015 is set in the ETACS-ECU, always diag-
nose the CAN main bus line.
CAUTION
Whenever the ECU is replaced, ensure that the
communication circuit is normal.
.
TROUBLE JUDGMENT
The ETACS-ECU receives multi center dis-
play-related signal from the multi center display (mid-
dle-grade type). If the ECU cannot receive the signal,
DTC 015 will be set.
.
TECHNICAL DESCRIPTION (COMMENT)
Current trouble
• Connector(s) or wiring harness in the CAN bus
lines between the multi center display unit (mid-
dle-grade type) and the ETACS-ECU, the power
supply system to the multi center display unit
(middle-grade type), the multi center display unit
(middle-grade type) itself, or the ETACS-ECU
may be defective.
Past trouble
• If DTC 015 is stored as a past trouble, carry out
diagnosis with particular emphasis on wiring and
connector(s) in the CAN bus line between the
multi center display unit (middle-grade type) and
the ETACS-ECU, and the power supply system to
the multi center display unit (middle-grade type).
For diagnosis procedures, refer to "How to cope
with past trouble" (Refer to GROUP 00, How to
treat past trouble
NOTE: You cannot find a past trouble, by the
MUT-III CAN bus diagnostics even if there is a
failure in CAN bus lines. In this case, refer to
GROUP 00, How to Cope with Intermittent Mal-
function
and check the CAN bus lines.
You can narrow down the possible cause of the
trouble by referring to the DTC, which is set
regarding the CAN communication-linked ECUs
(Refer to GROUP 54C, CAN Bus Line Diagnostic
Flow

• The wiring harness or connectors may have
loose, corroded, or damaged terminals, or termi-
nals pushed back in the connector
