DIAGNOSIS
Required Special Tools:
-
MB991223: Harness Set
-
MB992006: Extra Fine Probe
STEP 1. Check joint connector (CAN3) C-127, joint connector (CAN4) A-14 and intermediate connector A-13 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-127, joint connector (CAN4) A-14 and intermediate connector A-13 in good condition?
YES : Go to Step 2.
NO : Repair the damaged parts.
STEP 2. Check the wiring harness between joint connector (CAN3) C-127 and joint connector (CAN4) A-14 for open circuit.
CAUTION: Strictly observe the specified wiring harness repair procedure.
1. Disconnect joint connector (CAN3) C-127 and joint connector (CAN4) A-14, and check the wiring harness
