TRACTION CONTROL SYSTEM (TCL) DIAGNOSIS
TRACTION CONTROL SYSTEM (TCL)13C-8
DIAGNOSTIC TROUBLE CODE CHARTM1136003300022
During diagnosis, a DTC associated with other
system may be set when the ignition switch is
turned on with connector(s) disconnected. On
completion, confirm all systems for DTC(s). If
DTC(s) are set, erase them all.
NOTE: If the ABS-8 ECU or the active wheel
speed sensor are disconnected, or if the wiring is
an open/ short circuit, the ABS 8 ECU will shut
off power supply to the respective wheel speed
sensor. All other wheel speed sensors will oper-
ate normally. To restore the power supply, the
ignition switch must be turned to the "OFF" posi-
tion then to the "ON" position again.Follow the inspection chart that is appropriate for the
diagnostic trouble code.

DIAGNOSTIC TROUBLE CODE PROCEDURES
U1100 CAN Communications System Time Out Error Engine Related Data
If DTC U1100 is set in the ABS/TCL-ECU,
always diagnose the CAN main bus line. If
there is any fault in the CAN bus lines, an
incorrect DTC may be set.
Whenever the ABS/TCL-ECU is replaced,
ensure that the communication circuit is nor-
mal.
NOTE: If the ABS-8 ECU or the active wheel
speed sensor are disconnected, or if the wiring is
an open/ short circuit, the ABS 8 ECU will shut
off power supply to the respective wheel speed
sensor. All other wheel speed sensors will oper-
ate normally. To restore the power supply, the
ignition switch must be turned to the "OFF" posi-
tion then to the "ON" position again.
.
DTC SET CONDITION
The ABS/TCL-ECU receives engine system-related
signals from the ENGINE-ECU via CAN bus lines.

TROUBLESHOOTING HINTS (THE MOST
LIKELY CAUSES FOR THESE DTCS ARE
TO SET ARE:)
Damaged harness or connector.
Malfunction of the ENGINE-ECU.
