SECTION 12H - ELECTRICALLY ADJUSTABLE
REAR VISION MIRRORS
CAUTION:
This vehicle will be equipped with a Supplemental Restraint System (SRS). A SRS will
consist of either seat belt pre-tensioners and a driver's side air bag, or seat belt pre-
tensioners and a driver's and front passenger's side air bags. Refer to CAUTIONS,
Section 12M, before performing any service operation on, or around any SRS
components, the steering mechanism or wiring. Failure to follow the CAUTIONS
could result in SRS deplo yment, resulting in possible p ersonal injury or unnecessary
SRS system repairs.
CAUTION:
This vehicle may be equipped with LPG (Liquefied Petroleum Gas). In the interests of
safety, the LPG fuel system should be isolated by turning 'OFF' the manual service
valve and then draining the LPG serv ice lines, before any service w ork is carried out
on the vehicle. Refer to the LPG leaflet included with the Owner's Handbook for
details or LPG Section 2 for more specific servicing information.
1. GENERAL INFORMATION
Electrically adjustable rear vision mirrors are fitted as standard equipment on all VT Series Models.
Each exterior mirror assembly has two internal reversible motors: one to adjust the mirror face up and down
(vertical position), the other to adjust the mirror face right and left (horizontal position).
The rear vision mirrors are adjusted from the interior of the vehicle by a mirror control switch mounted in the driver's
side front door pull handle.
The control switch has two controls. A slide select switch that has two positions: Left mirror and Right mirror, and a
toggle type direction switch, which is used to control the direction of movement of the mirror face.
Figure 12H-1
1.1 CONTROL SWITCH OP ERATION
The mirror control switch is two switches in one; a
select switch which is used to select either the left
or right hand m irror, and a directional toggle s witch
which is used to move the mirror face in the
required direction.
The dire ctional toggle switch is designed to operate
in only one direction at a time and is activated by
depressing the edge of the toggle, causing the
toggle to ‘cock’ in the required direction.
Figure 12H-2
1.2 CIRCUIT OPERATION
With the switches in the positions shown in Fig.
12H-3, the LH exterior rear view mirror is moved
DOWNWARDS. Battery voltage from fuse F15 is
applied through the directional contacts of the
mir ror switch to circ uit 911 (Brown wire) to one side
of all mirror asse mbly motors.
The LH mirror vertical motor has a path to earth
through circuit 908 (Gr ey wire), through the LH s ide
select switch contacts, through the directional
contacts and circuit 156 (Black wire).
This allows the LH side vertical motor to operate
and turns the mirror DOWNWARDS until the
directional toggle switch is released.
W hen the directional toggle switch is depressed to
move the mirror UPW ARDS, the LH mirror vertical
motor receives voltage, however, the voltage is
reversed. Power is supplied through fuse F15,
through the directional toggle and LH side select
switch contacts , through circ uit 908 (Gr ey wire) and
through the motor. The motor is earthed through
circuit 911 (Brown wire), through the directional
switch contacts and circuit 156 (Black wire).
Figure 12H-3
The LH mirror INWARD and DOWNARD operation,
operates similarly. When the directional switch is
moved to the OUTWARD position, battery voltage
from fuse F15 is applied through the directional
centre contacts of the mirror control switch to circuit
911 (Brown wire) to one side of all mirr or ass embly
motors.
The LH mirror horizontal motor has a path to earth
through circuit 909 (Violet wire), through the LH
side select switch contacts, through the directional
contacts and through circuit 156 (Black wire).
This allows the LH side hor izontal motor to operate
and turns the mirror OUTWARDS until the
directional toggle switch is released.
W hen the directional toggle switch is depressed to
move the mirror INWARDS, the LH mirror
horizontal motor receives voltage, however the
voltage is reversed. Power to the motor is supplied
through fuse F15, through the directional and LH
side select switch contacts, through circuit 909
(Violet wire) and through the motor. The motor is
earthed through circuit 911 (Brown wire), through
the directional switch contacts and circuit 156
(Black w ire).
The RH mirror assembly operates in a similar
manner as the LH mirr or assem bly when the select
and directional switches contacts are selected,
except:
To m ove the RH mirr or down, power is supplied via
circuit 911 (Brown wire) and earthed through
circuits 904 (Light Blue wire) and 156 (Black wire).
To move the RH mirror up, power is supplied
through circuit 904 and earthed through circuits 911
and 156. To move the RH mirror out, power is
supplied via circ uit 911 and earthed thr ough c irc uits
905 and 156. To move the RH mirror in, power is
supplied through circuit 905 and earthed through
circuits 911 and 156.

2. SERVICE OPERATIONS
2.1 MIRROR ASSEMBLY
REMOVE
1. Disconnect battery earth lead.
2. Remove the mirror inner cover cap by gently
pryi ng cap away from door.
3. Remove door demist duct to allow access to
the exterior rear view mirror retaining screws
by pulling duct up and out of door trim.
Figure 12H-5
4. Using a right angled screwdriver, remove the
three screws securing the mirror to the door
and while supporting the mirror, disconnect the
mirror wiring harness connector.
5. Remove mirror assembly.
NOTE:
Fig. 12H-6 shows the door with the inner trim panel
removed. To remove the three exterior rear vision
mirror retaining screws, the inner door trim does
not have to be removed.
Figure 12H-6
TEST
The following operations, per formed with the m irror
assembly removed from the vehicle, check the
mirror assembly horizontal and vertical motors. If
the following operations prove that a mirror
assembly is faulty, replace the mirror assembly.
Using an ohmmeter c onnec ted to the electr ic mirror
connector, refer Fig. 12H-7, check continuity of
mirror wiring between the following terminals:
• Ter. 1 and Ter. 2
• Ter. 1 and Ter. 3
• Ter. 2 and Ter. 3
If the ohmmeter indicates an open circuit or a very
high resistance (more than 200 ohms) replace the
mirror assembly. If the mirror motor resistance is
acceptable, proceed to Step 2.
Figure 12H-7
2. Referring to Fig. 12H-8, connect leads from a
12 volt battery to the mirror harnes s connector
term inals nominated in the f ollowing c hart and
observe mirror movement.
