MB991223: Harness Set
⦆
MB992006: Extra Fine Probe
STEP 1. Check joint connector (CAN1) C-103, CAN box unit
connector C-13 and intermediate connector C-17 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
The strand end of the twisted wire should be within 10 cm
(4 inches) from the connector. For details refer to P.54D-8.

connector C-13 and intermediate connector C-17 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 CAN box unit connector C-13.
