AUTO A/C DIAGNOSIS
HEATER, AIR CONDITIONING AND VENTILATION55-60
DTC U1111: Multi-Center Display Unit Time-out
If DTC U1111 is set in the A/C-ECU, diagnose the
CAN main bus line.
Whenever the ECU is replaced, ensure that the
communication circuit is normal.
.
TROUBLE JUDGMENT
The A/C-ECU receives signals from the multi-center
display unit. If the ECU cannot receive the signal
r e l a t e d t o t h e m u l t i - c e n t e r d i s p l a y u n i t , D T C U 1111
will be set.
.
TECHNICAL DESCRIPTION (COMMENT)
Current trouble
Connector(s) or wiring harness in the CAN bus
lines between the A/C-ECU and the multi-center
display unit, the power supply system to the dis-
play unit, the display unit itself, or the A/C-ECU
may be defective.
Past trouble
W h e n D T C U 1111 i s s e t a s a p a s t t r o u b l e , c a r r y
out diagnosis with particular emphasis on con-
nector(s) or wiring harness in the CAN bus lines
between the A/C-ECU and the multi-center dis-
play unit, the power supply system to the display unit. If the connectors and wiring are normal, and
obviously the ECU or the multi-center display is
the cause of the trouble, replace the ECU or the
multi-center display. If in doubt, do not replace
the ECU or the display unit.
NOTE: For a past trouble, you cannot find it by
the diagnostic tool CAN bus diagnostics even if
there is a failure in the CAN bus lines. In this
case, refer to GROUP 00, How to Use Trouble-
shooting/Inspection Service Points
How to
Cope with Intermittent Malfunctions P.00-14.)
and check the CAN bus lines. You can narrow
down the possible cause of the trouble by refer-
ring to the DTC, which is set regarding the CAN
communication-linked ECUs (Refer to GROUP
54C
Explanation about the diagnostic tool CAN
bus diagnostics P.54C-6).
