INSPECTION
PROCEDURE
1. INSPECT OUTER MIRROR SWITCH ASSEMBLY (w/o Memory)
(a) Check the mirror select switch and mirror surface 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 |
(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.
(b) Check the switch illumination.
(1) Apply auxiliary battery voltage between the terminals of the light and check the operation of the light.
OK:
| Measurement Condition | Specified Condition |
|---|---|
| Auxiliary battery positive (+) → Terminal 10 (ILL+) Auxiliary battery negative (-) → Terminal 22 (ILL-) | Light comes on |
If the result is not as specified, replace the outer mirror switch assembly.
2. INSPECT OUTER MIRROR SWITCH ASSEMBLY (w/ Memory)
| (a) Check the mirror select switch. (w/o Automatic Retractable Mirror) (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 surface adjust switch. (w/o Automatic Retractable Mirror)
(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 (E1) - 13 (M+) | Mirror surface adjust switch pressed up | 90 to 110Ω |
| Off | 10 kΩ or higher | |
| Mirror surface adjust switch pressed down | 437 to 503Ω | |
| Off | 10 kΩ or higher | |
| Mirror surface adjust switch pressed left | 744 to 856Ω | |
| Off | 10 kΩ or higher | |
| Mirror surface adjust switch pressed right | 225 to 275Ω | |
| Off | 10 kΩ or higher |
If the result is not as specified, replace the outer mirror switch assembly.
(c) Check the switch illumination. (w/o Automatic Retractable Mirror)
(1) Apply auxiliary battery voltage between the terminals of the light and check the operation of the light.
OK:
| Measurement Condition | Specified Condition |
|---|---|
| Auxiliary battery positive (+) → Terminal 6 (ILL+) Auxiliary battery negative (-) → Terminal 15 (ILL-) | Light comes on |
If the result is not as specified, replace the outer mirror switch assembly.
| (d) Check the mirror retract switch. (w/ Automatic Retractable Mirror) (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. |
|
(e) Check the mirror select switch. (w/ Automatic Retractable Mirror)
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| 12 (E1) - 14 (MSW) | R | Below 10 Ω |
| L | 90 to 110 Ω | |
| Off | 10 kΩ or higher |
(f) Check the mirror surface adjust switch. (w/ Automatic Retractable Mirror)
(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 (E1) - 13 (M+) | Mirror surface adjust switch pressed up | 90 to 110 Ω |
| Off | 10 kΩ or higher | |
| Mirror surface adjust switch pressed down | 437 to 503 Ω | |
| Off | 10 kΩ or higher | |
| Mirror surface adjust switch pressed left | 744 to 856 Ω | |
| Off | 10 kΩ or higher | |
| Mirror surface adjust switch pressed right | 225 to 275 Ω | |
| Off | 10 kΩ or higher |
(g) Check the switch illumination. (w/ Automatic Retractable Mirror)
