1. Precaution

Before disassembling or reassembling parts, always
disconnect battery ground cable. When repairing
radio, control modules, etc. which are provided with
memory functions, record memory contents before
disconnecting battery ground cable. Otherwise, these
contents are cancelled upon disconnection.

Reassemble parts in reverse order of disassembly
procedure unless otherwise indicated.

Adjust parts to specifications contained in this
manual if so designated.

Connect connectors and hoses securely during
reassembly.

After reassembly, ensure functional parts operate
smoothly.
CAUTION:

Airbag system wiring harness is routed near the
electrical parts and switch.

All Airbag system wiring harness and connectors
are colored yellow. Do not use electrical test equip-
ment on these circuit.

Be careful not to damage Airbag system wiring har-
ness when servicing the ignition key cylinder.

7) Use engine grounding terminal or engine proper as the
grounding point to the body when measuring voltage and
resistance in the engine compartment.
8) Every MFI-related part is a precision part. Do not drop
them.
9) Observe the following cautions when installing a radio
in MFI equipped models.
CAUTION:

The antenna must be kept as far apart as possible
from the control unit.
(The ECM is located under the steering column, inside
of the instrument panel lower trim panel.)

The antenna feeder must be placed as far apart as
possible from the ECM and MFI harness.

Carefully adjust the antenna for correct matching.

When mounting a large power type radio, pay spe-
cial attention to the three items above mentioned.

Incorrect installation of the radio may affect the
operation of the ECM.
10) Before disconnecting the fuel hose, disconnect the
fuel pump connector and crank the engine for more than
five seconds to release pressure in the fuel system. If
engine starts during this operation, run it until it stops.
11) Problems in the electronic-controlled automatic trans-
mission may be caused by failure of the engine, the elec-
tronic control system, the transmission proper, or by a com-
bination of these. These three causes must be distin-
guished clearly when performing diagnostics.
12) Diagnostics should be conducted by rotating with
simple, easy operations and proceeding to complicated,
difficult operations. The most important thing in diagnostics
is to understand the customer’s complaint, and distinguish
between the three causes.
13) In AT vehicles, do not continue the stall for more than
five seconds at a time (from closed throttle, fully open
throttle to stall engine speed).
14) On ABS or ABS/TCS vehicle, when performing driving
test in jacked-up or lifted-up position, sometimes the warn-
ing light may be lit, but this is not a malfunction of the sys-
tem. The reason for this is the speed difference between
the front and rear wheels. After diagnosis of engine control
system, perform the ABS or ABS/TCS memory clearance
procedure of self-diagnosis system. [T9K0], 4-4c [T6D2] or [T9J0].>
