Inspection
1. INSPECT OUTER MIRROR SWITCH ASSEMBLY (w/o Memory)
(a) The L position of the left/right adjustment switch: Measure the resistance according to the value(s) in the table below.
Standard Resistance (for Left Side):
Tester Connection | Condition | Specified Condition |
|---|---|---|
4 (MLV) - 8 (B) 6 (M+) - 7 (E) |
UP |
Below 1 Ω |
OFF |
10 kΩ or higher |
|
4 (MLV) - 7 (E) 6 (M+) - 8 (B) |
DOWN |
Below 1 Ω |
OFF |
10 kΩ or higher |
|
5 (MLH) - 8 (B) 6 (M+) - 7 (E) |
LEFT |
Below 1 Ω |
OFF |
10 kΩ or higher |
|
5 (MLH) - 7 (E) 6 (M+) - 8 (B) |
RIGHT |
Below 1 Ω |
OFF |
10 kΩ or higher |
*a |
Component without harness connected (Outer Mirror Switch Assembly) |
If the result is not as specified, replace the switch assembly.
(b) The R position of the left/right adjustment switch: Measure the resistance according to the value(s) in the table below.
Standard Resistance (for Right Side):
Tester Connection | Condition | Specified Condition |
|---|---|---|
3 (MRV) - 8 (B) 6 (M+) - 7 (E) |
UP |
Below 1 Ω |
OFF |
10 kΩ or higher |
|
3 (MRV) - 7 (E) 6 (M+) - 8 (B) |
DOWN |
Below 1 Ω |
OFF |
10 kΩ or higher |
|
2 (MRH) - 8 (B) 6 (M+) - 7 (E) |
LEFT |
Below 1 Ω |
OFF |
10 kΩ or higher |
|
2 (MRH) - 7 (E) 6 (M+) - 8 (B) |
RIGHT |
Below 1 Ω |
OFF |
10 kΩ or higher |
*a |
Component without harness connected (Outer Mirror Switch Assembly) |
If the result is not as specified, replace the switch assembly.
2. INSPECT OUTER MIRROR SWITCH ASSEMBLY (w/ Memory)
(a) Check the switch functions. (1) Measure the resistance according to the value(s) in the table below. Standard Resistance:
If the result is not as specified, replace the outer mirror switch assembly. |
 |
