Outlander 2WD V6-3.0L (6B31) (2007)
FUNCTION
If the scan tool MB991958 cannot communicate with the occupant classification-ECU, this diagnosis result will be set.
TROUBLE JUDGMENT CONDITIONS
If a communication flag is not set for the occupant classification-ECU, the ETACS-ECU determines that there is a failure.
TROUBLESHOOTING HINTS
-
Malfunction of the connector [joint connector (CAN1), occupant classification-ECU connector improperly connected]
-
Malfunction of the wiring harness [open circuit between the occupant classification-ECU connector and the joint connector (CAN1), power supply
circuit to the occupant classification-ECU]
-
Malfunction of the occupant classification-ECU
DIAGNOSIS
Required Special Tools:
-
MB991223: Harness Set
-
MB992006: Extra Fine Probe
STEP 1. Check joint connector (CAN1) C-103, occupant classification-ECU connector D-34, D-34-2 and intermediate connector C-31 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 (CAN1) C-103, occupant classification-ECU connector D-34, D-34-2 and intermediate connector C-31 in good condition?
YES: Go to Step 2.
NO: Repair the damaged parts.
STEP 2. Check the wiring harness between joint connector (CAN1) C-103 and occupant classification-ECU connector D-31-2.
CAUTION: Strictly observe the specified wiring harness repair procedure.
1. Disconnect joint connector (CAN1) C-103 and occupant classification-ECU connector C-301, and check the wiring harness.
2. Check the wiring harness between joint connector (CAN1) C-103 (terminal No.11) and occupant classification-ECU connector D-31-2 (terminal
No.24)
3. Check the wiring harness between joint connector (CAN1) C-103 (terminal No.24) and occupant classification-ECU connector D-31-2 (terminal
No.25)
Q: Is the wiring harness between joint connector (CAN1) C-103 and occupant classification-ECU connector D-31-2 in good condition?
YES: Check the power supply circuit of the occupant classification-ECU. Refer to SRS, Air Bag Diagnosis.
NO: Repair the wiring harness between joint connector (CAN1) C-103 and occupant classification-ECU connector D-31-2.
Diagnostic Item 19
DIAGNOSTIC ITEM 19: Diagnose when the scan tool cannot receive the data sent by A/ C-ECU.
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.
