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 
rearview mirror adjusting switch 
wire harness connector DR09 
corresponding terminals (note: do 
not disconnect wire harness 
connector DR09).

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.
