The values of the resistances of mine steering wheel command are:
“ENTER”, “+” and “-” switch resistance
All switches released (OFF): 4700 - 5600 kΩ I read 5,17k
A) “ENTER” switch (1) pushing on (ON): 50 - 60 Ω I read 0,06K
B) “+” switch (2) pushing on (ON): 120 - 140 Ω I read 0,13K
“-” switch (3) pushing on (ON): 220 - 260 Ω I read 0,24K
“MODE”, and switch resistance
All switches released (OFF): 4700 - 5600 kΩ I read 5,17K
C) “MODE” switch (4) pushing on (ON): 370 - 460 Ω I read 0,42K
D) witch (5) pushing on (ON): 680 - 820 Ω I read 0,7K
switch (6) pushing on (ON): 1400 - 1700 Ω I read 1,57K
SWC reads the values of enter and those of volume + or - too much near.
