INSPECTION
PROCEDURE
1. INSPECT OUTER MIRROR SWITCH ASSEMBLY (w/ Memory)
| (a) Check the mirror retract switch. (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. |
|
(b) Check the mirror select switch.
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| 12 (E) - 14 (MSW) | R | Below 10 Ω |
| L | 90 to 110 Ω | |
| Off | 10 kΩ or higher |
If the result is not as specified, replace the outer mirror switch assembly.
(c) Check the mirror adjust switch.
(1) Select the mirror select switch to the L position or R position.
(2) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| 12 (E) - 13 (M+) | Mirror adjust switch pressed up | 90 to 110 Ω |
| Off | 10 kΩ or higher | |
| Mirror adjust switch pressed down | 437 to 503 Ω | |
| Off | 10 kΩ or higher | |
| Mirror adjust switch pressed left | 744 to 856 Ω | |
| Off | 10 kΩ or higher | |
| Mirror adjust switch pressed right | 225 to 275 Ω | |
| Off | 10 kΩ or higher |
If the result is not as specified, replace the outer mirror switch assembly.
(d) Check the switch illumination.
(1) Apply auxiliary battery voltage between the terminals of the light and check the operation of the light.
Standard:
| Auxiliary Battery Connection | Specified Condition |
|---|---|
| Auxiliary Battery positive (+) → 6 (ILL+) Auxiliary Battery negative (-) → 15 (ILL-) | Light comes on |
If the result is not as specified, replace the outer mirror switch assembly.
2. INSPECT OUTER MIRROR SWITCH ASSEMBLY (w/o Memory)
| (a) Check the mirror retract switch. (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. |
|
(b) Check the mirror select switch and mirror adjust switch.
(1) Select the mirror select switch to the L position.
(2) Measure the resistance according to the value(s) in the table below.
Standard Resistance (for left side):
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| 20 (VL) - 13 (B) 19 (M+) - 15 (E) | Up | Below 1 Ω |
| Off | 10 kΩ or higher | |
| 20 (VL) - 15 (E) 19 (M+) - 13 (B) | Down | Below 1 Ω |
| Off | 10 kΩ or higher | |
| 21 (HL) - 13 (B) 19 (M+) - 15 (E) | Left | Below 1 Ω |
| Off | 10 kΩ or higher | |
| 21 (HL) - 15 (E) 19 (M+) - 13 (B) | Right | Below 1 Ω |
| Off | 10 kΩ or higher |
If the result is not as specified, replace the outer mirror switch assembly.
(3) Select the mirror select switch to the R position.
(4) Measure the resistance according to the value(s) in the table below.
Standard Resistance (for right side):
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| 18 (VR) - 13 (B) 19 (M+) - 15 (E) | Up | Below 1 Ω |
| Off | 10 kΩ or higher | |
| 18 (VR) - 15 (E) 19 (M+) - 13 (B) | Down | Below 1 Ω |
| Off | 10 kΩ or higher | |
| 23 (HR) - 13 (B) 19 (M+) - 15 (E) | Left | Below 1 Ω |
| Off | 10 kΩ or higher | |
| 23 (HR) - 15 (E) 19 (M+) - 13 (B) | Right | Below 1 Ω |
| Off | 10 kΩ or higher |
If the result is not as specified, replace the outer mirror switch assembly.
(c) Check the switch illumination.
(1) Apply auxiliary battery voltage between the terminals of the light and check the operation of the light.
Standard:
| Auxiliary Battery Connection | Specified Condition |
|---|---|
| Auxiliary Battery positive (+) → 10 (ILL+) Auxiliary Battery negative (-) → 22 (ILL-) | Light comes on |
If the result is not as specified, replace the outer mirror switch assembly.
