Working Precautions - Subaru Legacy 2002 Service Manual

2. Working Precautions

A: PRECAUTIONS WHEN WORKING
WITH THE PARTS MOUNTED ON
THE VEHICLE
S903706G38
1) When working under a vehicle which is jacked-
up, always be sure to use safety stands.
2) The parking brake must always be applied dur-
ing working. Also, in automatic transmission
vehicles, keep the select lever set to the P (Park-
ing) range.
3) Be sure the workshop is properly ventilated
when running the engine. Further, be careful not to
touch the belt or fan while the engine is operating.
4) Be careful not to touch hot metal parts, espe-
cially the radiator and exhaust system immediately
after the engine has been shut off.
B: PRECAUTIONS IN TROUBLE
DIAGNOSIS AND REPAIR OF
ELECTRIC PARTS
1) The battery cable must be disconnected from
the battery's (−) terminal, and the ignition switch
must be set to the OFF position, unless otherwise
required by the diagnostics.
2) Securely fasten the wiring harness with clamps
and slips so that the harness does not interfere
with the body end parts or edges and bolts or
screws.
3) When installing parts, be careful not to catch
them on the wiring harness.
4) When disconnecting a connector, do not pull
the wires, but pull while holding the connector
body.

5) Some connectors are provided with a lock. One
type of such a connector is disconnected by push-
ing the lock, and the other, by moving the lock up.
In either type the lock shape must be identified
before attempting to disconnect the connector.
To connect, insert the connector until it snaps and
confirm that it is tightly connected.
6) When checking continuity between connector
terminals, or measuring voltage across the termi-
nal and ground, always contact tester probe(s) on
terminals from the wiring connection side. If the
probe is too thick to gain access to the terminal,
use "mini" test leads.
To check water-proof connectors (which are not
accessible from the wiring side), contact test
probes on the terminal side being careful not to
bend or damage the terminals.
7) Sensors, relays, electrical unit, etc., are sensi-
tive to strong impacts.
Handle them with care so that they are not dropped
or mishandled.
