DTC U1100: CAN Communications System Time Out Error Engine Related Data DTC SET CONDITION The ABS/TCL-ECU < FWD > or TCL/ASC-ECU < AWD > receives engine
system-related signals from the powertrain control module (PCM) via CAN bus
lines. TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THESE DTCS ARE TO SET ARE:)
Damaged harness or connector. Malfunction of the PCM. Malfunction of the ABS/TCL-ECU < FWD > or TCL/ASC-ECU < AWD >.
DIAGNOSIS Required Special Tools: CAUTION:
If DTC U1100 is set in the ABS/TCL-ECU < FWD >
or TCL/ASC-ECU < AWD >, 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 < FWD > or
TCL/ASC-ECU < AWD > is replaced, ensure that
