Inspect the left front door rearview mirror regulating switch grounding circuit.

(a) Disconnect left front door

rearview mirror adjusting switch
harness connector DR09.

(b) Inspect

resistance between left

front door rearview mirror
adjusting switch wire harness
connector DR09 terminal No. 8
and grounding circuit.

Resistance standard value :is less than
1Ω

Confirm if the resistance conforms to
standard value.

Inspect the energy conduction property of the left front door rearview mirror regulating
switch.

(a) Turn on ignition switch to ACC

position.

(b) Operate electric rearview mirror

adjusting button of left front door
rearview mirror adjusting switch.

(c) Use multimeter to measure

voltage between left front door

Replace power rearview mirror adjusting switch,

(a) Replace power rearview mirror adjusting switch. Refer to11.4.8.4 power rearview mirror

adjusting switch replacement.

Confirm whether the electric rear view mirror is working normally?

7

Inspect working condition of the electric rearview mirror of the fault side.

(a) Put left and right selection switch to the electric rearview mirror on fault side to allow up and

down, left and right adjustment.

Confirm whether the electric rearview mirror can be regulated up and down.

8

Inspect the upper and lower control signal circuit of the fault-side electric rearview
mirror.

(a) Operate electric rearview mirror

up and down adjusting button of
left front glass lifter switch

(b) Meanwhile, use multimeter to

measure voltage between
terminal A and B of electric
rearview mirror wire harness
connector DR08 (left) or DR18
(right side) on fault side.
