Inspection [09/2014 - ]: Procedure
- INSPECT HEADUP DISPLAY SWITCH ASSEMBLY
- 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.
