Brake Note

NOTE
All brake fasteners are important attaching
parts in that they could affect the
performance of vital parts and systems, and/
or could result in major repair expense. They
must be replaced with one of same part
number or with an equivalent part if
replacement becomes necessary. Do not use
a replacement part or lesser quality or
substitute design. Torque values must be
used as specified during reassembly to
assure proper retention of all parts. There is
to be no welding as it may result in extensive
damage and weakening of the metal.

Electrical Circuit Inspection Procedure
S3RH0A0006001
While there are various electrical circuit inspection
methods, described here is a general method to check
its open and short circuit by using an ohmmeter and a
voltmeter.
Open Circuit Check
Possible causes for the open circuit are as follows. As
the cause is in the connector or terminal in many cases,
they need to be checked particularly carefully.
• Loose connection of connector
• Poor contact of terminal (due to dirt, corrosion or rust
on it, poor contact tension, entry of foreign object etc.)
• Wire harness being open
When checking system circuits including an electronic
control unit such as ECM, TCM, ABS control module,
etc., it is important to perform careful check, starting with
items which are easier to check.
1) Disconnect negative (–) cable from battery
2) Check each connector at both ends of the circuit
being checked for loose connection. Also check lock
condition of connector if equipped with connector
lock.
3) Using a test male terminal, check both terminals of
the circuit being checked for contact tension of its
female terminal. Check each terminal visually for
poor contact (possibly caused by dirt, corrosion, rust
entry of foreign object, etc.). At the same time, check
to make sure that each terminal is locked in the
connector fully.
4) Using continuity check or voltage check the following
procedure, check the wire harness for open circuit
(2) and poor connection with its terminals. Locate
abnormality, if any.

1. Check contact tension by inserting and removing just for once.
1. Looseness of crimping
3. Thin wire (single strand of wire)
