Step D - Damage type 6, Repair of damaged CAN-bus
cables
Important: CAN-bus
wires are protected to outside interference by means of twisted
wires. When repairing CAN-bus wires be sure to keep this twisting
of wires intact. The wires should make one winding per 2.5 cm
length.
D6.1 Strip insulation from lead ends
- Sever defective cable at suitable location.
- Strip outer isolation over a length of approx. 4 cm. Be sure
not to damage the isolation of the inner wires.
Note: Wire strip tool
MKM-6383 can be used for this
purpose where it is used twice, removing two times approximately 2
cm of outer isolation.
- Using MKM-6383 strip isolation
from one lead as close as possible to the outer isolation
- Cut of excessive length of wire with approximately 5 mm
stripped wire remaining
- Strip isolation of other wire over a length of approx 5
mm.
- The end result is a cable end with two stripped wires where one
wire is approx. 3 cm longer than the other

D6.2 Prepare replacement piece
- Cut-off enough length from the replacement CAN-bus pigtail to
be able to bridge both ends.
- Remove isolation and shorten wire at both ends as described
above.
Note: When shortening
one wire at each end be sure to match this with the wire lengths at
the original cable ends.

D6.3 - Pull on shrink-down tube
- Select shrink-down plastic tube RBK-1 and cut in half. Guide
each half over a long lead end.

|
D6.4 - Connect and insulate lead ends
Connect the original CAN-bus wires with the replacment piece
lead ends in accordance with steps D1.1 to D1.3.
Shrink on shrink down tube in accordance with D1.4 .
Insulate wiring harness according to D1.6 .
