Outlander 4WD L4-2.4L (4B12) (2008)
CAN Communication Circuit (Part 3)
FUNCTION
If a short to power supply or ground, open circuit or line-to-line short is present at either CAN_H or CAN_L side on the CAN-B lines, this diagnosis
result will be set.
TROUBLE JUDGEMENT CONDITIONS
When CAN-B lines communication is normal, and diagnostic trouble code U0019 is set, the ETACS-ECU determines that there is a failure.
TROUBLESHOOTING HINTS
-
Malfunction of the connector (short to power supply or ground in connector or improperly connected)
-
Malfunction of the wiring harness (short to power supply or ground, open circuit or line-to-line short in CAN bus lines)
-
Faulty ECU(s) (internal short to power supply or ground)
DIAGNOSIS
Required Special Tools:
-
MB991223: Harness Set
-
MB992006: Extra Fine Probe
STEP 1. Check the wiring harness between ETACS-ECU connector C-301 and body ground for a short to ground. Measure the resistance at
ETACS-ECU connector C-301.
CAUTION:
-
Disconnect the negative battery terminal.
-
A digital multimeter should be used.
-
The test wiring harness should be used.
1. Disconnect ETACS-ECU connector C-301, and measure the voltage at the wiring harness side of ETACS-ECU connector.
