Warnings in diagnosis section

Details regarding warnings

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, a component 
connected to the CAN bus line may be broken.

−

CAUTION

A digital multimeter should be used.

When measuring resistance value or voltage in 
CAN bus lines, use a digital multimeter. If not 
using a digital multimeter, the equipments, which 
are connected through the CAN communication 
lines, may be damaged.

CAUTION

When measuring the resistance, disconnect the 
negative battery terminal.

Disconnect the negative battery terminal when 
measuring the resistance value in the CAN bus 
line. If you fail to do so, the equipments, which 
are connected through the CAN communication 
lines, may be damaged.

PRECAUTIONS ON HOW TO REPAIR THE CAN BUS LINES

PRECAUTIONS ON HOW TO REPAIR THE CAN BUS LINES

M1548301900370

.

PRECAUTIONS ON HOW TO REPAIR THE CAN 
BUS LINES

• If the CAN bus line(s) are repaired, renew all the twisted 

wires between the end connectors. If the wiring harness is 
partially repaired, or only CAN_L or CAN_H line is repaired, 
noise suppression is deteriorated, causing a communica-
tion error.

CAUTION

The test wiring harness should be used.

Always use the test harness when measuring the 
voltage or resistance value at the female 
connector. If you fail to do so, connectors may be 
damaged.

CAUTION

The strand end of the twist wire should be within 
10 cm from the connector.

If you repair the wire due to a defective 
connector or its terminal or harness wire, you 
should cut the wire so that the strand end of the 
twist wire should be within 10 cm (4 inches) from 
the connector as shown. If it exceeds 10 cm (4 
inches), twist the wiring harness just like the 
original twisted wire. If the strand end exceeds 
10 cm (4 inches), a communication error may be 
caused.

CAUTION

Strictly observe the specified wiring harness 
repair procedure.

When you repair a CAN bus line, observe the 
precautions on how to repair the CAN bus line 
strictly. Refer to 

P.54C-8

. If a new wire is added 

or a splice point is modified for the CAN_L or 
CAN_H line, an error in the CAN communication 
may be caused.
