Another Scion TC steering wheel button thread
OK so I've read through all of the steering wheel button posts and I've gotten a few good results. I'll share my steps.
1. Found which/how many wires are used. (Two, Solution D :censored:)
2. Measure resistance for button presses, values are measured @20kOhms:
a. No press: 1.
b. Vol +: 0.99
c. Vol -: 3.1
d. Track +: 0.0
e. Track -: 0.33/ 0.32
f. Mode: No change. WTF?
I guess where I get retarded is... what are these values? If the multimeter is set at 20kOhms, does (a) give me a value of 20k? (b) 19800 (c) 62000 etc.
Also, any ideas as to why the MODE isn't showing up?
