DIAGNOSIS
CAUTION:
If DTC C1397 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
the communication circuit is normal. The A/T system-related DTC may be set when
