1992 MAZDA PROTEGE light

IMPORTANT INFORMATION
IMPORTANT INFORMATION
BASIC ASSUMPTIONS
This workshop manual assumes that you have certain special tools that are necessary for the safe and effi-
cient performance of service operations on Mazda vehicles and that you know how to use them properly.
It also assumes that you are familiar with automobile systems and basic service and repair procedures. You
should not attempt to use this manual unless these assumptions are correct and you understand the conse-
quences described below.
SAFETY RISK
This manual contains certain notes, warnings, and other precautionary information that you should carefully
read and follow to reduce the risk of personal injury to yourself or others and the risk of improper service
that may damage the vehicle or render it unsafe. If there is no such information in regard to any specific
service method, this does not mean there is no possibility that personal safety or vehicle safety will be
jeopardized by the use of incorrect methods or tools.
POSSIBLE LOSS OF WARRANTY
The manufacturer’s warranty on Mazda vehicles and engines can be voided if improper service or repairs
are performed by persons other than those at an Authorized Mazda Dealer.
WARNING ON LUBRICANTS AND GREASES
Avoid all prolonged and repeated contact with mineral oils, especially used oils. Used oils contaminated
during service (e.g., engine sump oils) are more irritating and more likely to cause serious effects, including
skin cancer, in the event of gross and prolonged skin contact.
Wash skin thoroughly after work involving oil.
Protective hand cleaners may be of value provided they can be removed from the skin with water. Do not
use gasoline, paraffin, or other solvents to remove oil from the skin.
Lubricants and greases may be slightly irritating to the eyes.
Repeated or prolonged skin contact should be avoided by wearing protective clothing if necessary. Particu-
lar care should be taken with used oils and greases containing lead. Do not allow work clothing to be con-
taminated with oil. Dry clean or launder such clothing at regular intervals.

Test Light
The test light, as shown in the figure, uses a 12V bulb. The
two lead wires should be connected to probes.
The test light is used for simple voltage checks and for check-
ing for short circuits.
Caution
l When checking the control unit, never use a bulb
over 3.4W.

Jumper Wire
The jumper wire is used for testing by shorting across switch
terminals and ground connections.
Caution
l Do not connect a jumper wire from the power source
line to a body ground; this may cause burning or
other damage to harnesses or electronic com-
ponents.
Voltmeter
The DC voltmeter is used to measure of circuit voltage. A volt-
meter with a range of 15V or more is used by connecting the
positive (-t-) probe (red lead wire) to the point where voltage
is to be measured and the negative (-) probe (black lead
wire) to a body ground.
-,’
Diagnosis Connector
Insert the probe into the service hole when connecting a jum-
per wire to the diagnosis connector.
Caution
. Do not insert the jumper wire probe into the diag-
nosis connector terminal, which may damage the
terminal.
Ohmmeter
The ohmmeter is used to measure the resistance between two
points in a circuit and also to check for continuity and diagno-
sis of short circuits.
Caution
l Do not attempt to connect the ohmmeter to any cir-
cuit to which voltage is applied; this may burn or
otherwise damage the ohmmeter.

2. Check the terminals of waterproof connectors from the con-
nector side, as they cannot be accessed from the wire har-
ness side.
Caution
l Use fine wire to prevent damage to the terminal.
l Do not damage the terminal when inserting the
tester lead.

Terminals
Inspection
Pull lightly on individual wires to check that they are secured
in the terminal.
Replacement of terminals
Use the appropriate tools to remove the terminal as shown.
When installing the terminal, be sure to insert it until it locks
securely.
< Female >
Insert a thin piece of metal from the terminal side of the con-
nectar, and then, with the terminal locking tab pressed down,
pull the terminal out from the connector.
< Male >
Sensors, Switches, and Relays
Handle sensors, switches, and relays carefully. Do not drop
them or strike them against other parts.

Fuse
Replacement
1. When replacing a fuse, be sure to replace it with one of
specified capacity.
If a fuse again fails after it has been replaced, the circuit
probably has a short circuit and the wiring should be
checked.
2. Be sure the negative battery terminal is disconnected be-
fore replacing a main fuse (80A).
3. When replacing a pullout fuse, use the fuse puller supplied
in the fuse box cover.
