| *a | Component without harness connected (Headup Display Switch Assembly) |
(a) Check the resistance.
Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Switch Condition | Specified Condition |
|---|---|---|
| 12 (ILU) - 6 (CH) | HUD switch off (Not pushed) | 100 kΩ |
| 10 (ILD) - 6 (CH) | 100 kΩ | |
| 12 (ILU) - 6 (CH) | HUD switch on (Pushed) | Below 1 Ω |
| 10 (ILD) - 6 (CH) | 100 kΩ | |
| 12 (ILU) - 6 (CH) | TILT switch (UP) on (Pushed) | 100 kΩ |
| 10 (ILD) - 6 (CH) | 3210 Ω | |
| 12 (ILU) - 6 (CH) | TILT switch off (Not pushed) | 100 kΩ |
| 10 (ILD) - 6 (CH) | 100 kΩ | |
| 12 (ILU) - 6 (CH) | TILT switch (DOWN) on (Pushed) | 100 kΩ |
| 10 (ILD) - 6 (CH) | 1010 Ω | |
| 12 (ILU) - 6 (CH) | RHEOSTAT switch (ILL UP) on (Pushed) | 100 kΩ |
| 10 (ILD) - 6 (CH) | 330 Ω | |
| 12 (ILU) - 6 (CH) | RHEOSTAT switch off (Not pushed) | 100 kΩ |
| 10 (ILD) - 6 (CH) | 100 kΩ | |
| 12 (ILU) - 6 (CH) | RHEOSTAT switch (ILL DOWN) on (Pushed) | 100 kΩ |
| 10 (ILD) - 6 (CH) | Below 1 Ω | |
| 12 (ILU) - 6 (CH) | DISP switch off (Not pushed) | 100 kΩ |
| 10 (ILD) - 6 (CH) | 100 kΩ | |
| 12 (ILU) - 6 (CH) | DISP switch on (Pushed) | 330 Ω |
| 10 (ILD) - 6 (CH) | 100 kΩ |
If the result is not as specified, replace the headup display switch assembly.
| (b) Check the illumination. Apply battery voltage to the connector and check the illumination condition. OK:
If the result is not as specified, replace the headup display switch assembly. |
