FUNCTION
If a short to power supply is present in the CAN-C
lines, this diagnosis result will be set.

TROUBLE JUDGEMENT CONDITIONS
The wiring harness wire or connectors may have
loose, corroded, or damage terminals, or terminals
pushed back in the connector, or an ECU may be
defective.

TROUBLESHOOTING HINTS

｠

Malfunction of the connector (short to power supply
in connector)

｠

Malfunction of the wiring harness (short to power
supply in the CAN-C main or sub bus lines)

｠

Malfunction of the ECU (ETACS-ECU, or ECUs on
CAN-C lines failed)
