(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
1 (HO) - Terminal-A	Always	Below 1 Ω
10 (AU1) - 7 (EAU)	No switch pushed	95 to 105 kΩ
	Up switch pushed	Below 2.5 Ω
	Down switch pushed	313 to 345 Ω
	Volume+ switch pushed	950 to 1050 Ω
	Volume- switch pushed	2955 to 3265 Ω
9 (AU2) - 7 (EAU)	No switch pushed	95 to 105 kΩ
	MODE/HOLD switch pushed	Below 2.5 Ω
	On hook switch pushed	313 to 345 Ω
	Off hook switch pushed	950 to 1050 Ω
	Voice switch pushed	2955 to 3265 Ω
8 (AU3) - 7 (EAU)	No switch pushed	95 to 105 kΩ
	Enter switch pushed	Below 2.5 Ω
	Back switch pushed	313 to 345 Ω
	Right switch pushed	950 to 1050 Ω
	Left switch pushed	2955 to 3265 Ω

HINT:

If the result is not as specified, replace the steering pad switch assembly.
