Outlander 2WD V6-3.0L (6B31) (2007)
CAN Communication Circuit Part 2
FUNCTION
If the scan tool MB991958 cannot communicate with the ASC-ECU, this diagnosis result will be set.
TROUBLE JUDGEMENT CONDITIONS
If a communication flag is not set for the ASC-ECU, the ETACS-ECU determines that there is a failure.
TROUBLESHOOTING HINTS
-
Malfunction of the connector [joint connector (CAN3) or ASC-ECU connector improperly connected]
-
Malfunction of the wiring harness [open circuit between the ASC-ECU and the joint connector (CAN3), power supply circuit to the ASC-ECU]
-
Malfunction of the ASC-ECU
DIAGNOSIS
Required Special Tools:
-
MB991223: Harness Set
-
MB992006: Extra Fine Probe
STEP 1. Check joint connector (CAN3) C-01 and ASC-ECU connector A-02 for loose, corroded or damaged terminals, or terminals pushed
back in the connector.
CAUTION: The strand end of the twisted wire should be within 10 cm (4 inches) from the connector.
Q: Are joint connector (CAN3) C-01 and ASC-ECU connector A-02 in good condition?
YES: Go to Step 2.
NO: Repair the damaged parts.
STEP 2. Check the wiring harness between joint connector (CAN3) C-01 and ASC-ECU connector A-02.
CAUTION: Strictly observe the specified wiring harness repair procedure.
1. Disconnect joint connector (CAN3) C-01 and ASC-ECU connector A-02, and check the wiring harness.
2. Check the wiring harness between joint connector (CAN3) C-01 (terminal No.6) and ASC-ECU connector A-02 (terminal No.11)
3. Check the wiring harness between joint connector (CAN3) C-01 (terminal No.19) and ASC-ECU connector A-02 (terminal No.15)
Q: Is the wiring harness between joint connector (CAN3) C-01 and ASC-ECU connector A-02 in good condition?
YES: Check the power supply circuit of the ASC-ECU. Refer to Active Skid Control System (ASC), Troubleshooting.
NO: Repair the wiring harness between joint connector (CAN3) C-01 and ASC-ECU connector A-02.
Diagnostic Item 11
DIAGNOSTIC ITEM 11: Diagnose when the scan tool cannot receive the data sent by ECM.
CAUTION: When servicing a CAN bus line, ground yourself by touching a metal object such as an unpainted water pipe. If you fail to do so, a
component connected to the CAN bus line may be damaged.
