Outlander 2WD V6-3.0L (6B31) (2007)
CAN Communication Circuit Part 2
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.
CAUTION: Disconnect the negative battery terminal.
CAUTION: A digital multimeter should be used.
CAUTION: The test wiring harness should be used.
1. Disconnect joint connector (CAN2), and measure the resistance at the wiring harness side of joint connector (CAN2).
