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

TROUBLE JUDGEMENT CONDITIONS
If DTC U1120 is set, the ETACS-ECU determines that
there is a failure.

TROUBLESHOOTING HINTS

｠

Malfunction of the connector (short to ground inside
connector)

｠

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

｠

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

STEP 1. Check the wiring harness between joint connector
(CAN2) C-04 and steering wheel sensor connector C-209 for
a short to ground. Measure the resistance at joint connector
(CAN2) C-04.

Disconnect the negative battery terminal. For details refer
to P.54D-8.
