Toyota’s confidence in its products and commitment to cus-
tomer satisfaction are demonstrated by outstanding warranty
coverage — including a lifetime guarantee on replacement
mufflers, exhaust pipes, shock absorbers, struts and strut
cartridges. When purchased at and installed by a Toyota dealer-
ship, these Genuine Toyota Parts are guaranteed to the original
purchaser for the life of the vehicle. This includes coverage for
parts
and labor.
Compare the guarantees offered on these parts by aftermarket
repair shops — many don’ t offer the extensive coverage Toyota
does. And remember that only Genuine Toyota Parts are manu-
factured to your vehicle’s exact specifications. So don’ t com-
promise; when replacement time comes, count on your Toyota
dealer for quality, performance and the peace of mind that
comes with a factory- backed lifetime guarantee.
For complete details of the Toyota Lifetime Guarantee, see an authorized
Toyota dealer.

circuit shown in the SYSTEM CIRCUITS SECTION.

B
The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.

FINDING A SHORT CIRCUIT
(a)Remove the blown fuse and disconnect all loads of the fuse.
(b)Connect a test light in place of the fuse.
(c)Establish conditions in which the test light comes on.
Example:
[A] ± Ignition SW on
[B] ± Ignition SW and SW 1 on
[C] ± Ignition SW, SW 1 and Relay on (Connect the
Relay) and SW 2 off (or Disconnect SW 2)
(d)Disconnect and reconnect the connectors while watching the
test light.
The short lies between the connector where the test light
stays lit and the connector where the light goes out.
(e)Find the exact location of the short by lightly shaking the
problem wire along the body.
CAUTION:
(a) Do not open the cover or the case of the ECU unless
absolutely necessary. (If the IC terminals are touched,
the IC may be destroyed by static electricity.)
(b) When replacing the internal mechanism (ECU part) of
the digital meter, be careful that no part of your body or
clothing comes in contact with the terminals of leads
from the IC, etc. of the replacement part (spare part).
DISCONNECTION OF MALE AND FEMALE
CONNECTORS
To pull apart the connectors, pull on the connector itself, not
the wire harness.
HINT : C h e c k t o s e e w h a t k i n d o f connector you are
disconnecting before pulling apart.

* The titles given inside the components are the names of the terminals (terminal codes) and are not treated as being
abbreviations.
