Lancer Sportback L4-2.4L (4B12) (2010)
CAN-C Communication Circuit [RALLIART] (Part 2)
FUNCTION
If a failure is present in the wiring harness between the joint connector (CAN2) and the joint connector (CAN3), this diagnosis result will be set.
TROUBLE JUDGEMENT CONDITIONS
If a communication flag is not set for any ECU connected to CAN-C (CAN3, and CAN4 [RALLIART]), it is determined that a failure has occurred.
TROUBLESHOOTING HINTS
-
Malfunction of the connector [joint connector (CAN2), joint connector (CAN3) or intermediate connector failed]
-
Malfunction of the wiring harness [open circuit between joint connector (CAN2) and joint connector (CAN3)]
DIAGNOSIS
Required Special Tools:
-
MB991223: Harness Set
-
MB992006: Extra Fine Probe
STEP 1. Check joint connector (CAN2) C-05, joint connector (CAN3) C-124 and intermediate connector C-128 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 (CAN2) C-05, joint connector (CAN3) C-124 and intermediate connector C-128 in good condition?
YES : Go to Step 2.
NO : Repair the damaged parts.
STEP 2. Check the wiring harness between joint connector (CAN2) C-05 and joint connector (CAN3) C-124 for open circuit.
CAUTION: Strictly observe the specified wiring harness repair procedure.
1. Disconnect joint connector (CAN2) C-05 and joint connector (CAN3) C-124, and check the wiring harness.
2. Check the wiring harness between joint connector (CAN2) C-05 (terminal 5) and joint connector (CAN3) C-124 (terminal 5)
OK: Continuity exists (2 ohm or less)
