Pedal vibration
and noise occur
when any electric
switch is operated.Noise occurs in
body harnesses.Check that car
telephone, personal
receiver transmitter,
etc. are installed prop-
erly as required by
laws or regulations.
Check that harnesses
are routed properly.
Check that harnesses
are free from twisting
(or maintained to less
than 35-mm pitch).
Check that harnesses
are not routed too
closely to other electri-
cal units which could
serve as a source of
noise.

Check if vehicle
profile is correct.
(Front end of
vehicle tilts down
greater than rear
end.)Check wheel arch height
and adjust as required.
Warning light
comes on.Check using on-board
diagnosis system, accord-
ing to trouble code.
Warning light will
not go on for 1.5
seconds after igni-
tion switch is
turned on.Trouble in warning light
drive circuit. [T7A0].>

11) Each connector number shown in the wiring diagram
corresponds to that in the wiring harness. The location of
each connector in the actual vehicle is determined by read-
ing the first character of the connector (for example, a“F”
for F8,“i”for i16, etc.) and the type of wiring harness.
The first character of each connector number refers to the
area or system of the vehicle, as indicated in table below.

1. General Description

3. Working Precautions
1. PRECAUTIONS WHEN WORKING WITH THE
PARTS MOUNTED ON THE VEHICLE
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 during work-
ing. Also, in automatic transmission vehicles, keep the
select lever set to the P (Parking) range.
3) Be sure the workshop is properly ventilated when run-
ning 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, especially the
radiator and exhaust system immediately after the engine
has been shut off.
2. PRECAUTIONS IN TROUBLE DIAGNOSIS AND
REPAIR OF ELECTRIC PARTS
1) The battery cable must be disconnected from the bat-
tery’s () terminal, and the ignition switch must be set to the
OFF position, unless otherwise required by the diagnos-
tics.
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.
G6M0212
4) When disconnecting a connector, do not pull the wires,
but pull while holding the connector body.
