Inspection [08/2013 - 08/2016]: Procedure
- INSPECT STEERING PAD SWITCH ASSEMBLY (w/ Back Switch of Steering Pad Switch Assembly)
- Measure the resistance according to the value(s) in the table below.
*a Component without harness connected
(Steering Pad Switch Assembly)*b Volume+ *c Volume- *d Back *e MODE/HOLD *f Up *g Down *h Left *i Right *j Enter *k Off hook *l On hook *m Voice *n DISP Standard Resistance
Tester Connection Condition Specified Condition z5-1 (HO) - A-1 (HO) Always Below 2.5 Ω z5-11 (AU1) - z5-8 (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 z5-10 (AU2) - z5-8 (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 z5-9 (AU3) - z5-8 (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 z5-2 (+DP) - z5-3 (-DP) No switch pushed 10 kΩ or higher DISP switch pushed Below 2.5 Ω z5-6 (SUP) - z4-2 (SUP) Always Below 2.5 Ω z5-7 (ECC) - z4-7 (ECC) Always Below 2.5 Ω z5-12 (SDN) - z4-3 (SDN) Always Below 2.5 Ω HINT:
If the result is not as specified, replace the steering pad switch assembly.
- Check the illumination.
*a Component without harness connected
(Steering Pad Switch Assembly)- - - Connect a battery positive (+) lead to terminal 5 (IL+2) and a negative (-) lead to terminal 3 (-DP) of the steering pad switch assembly connector.
- Check that the switch illumination comes on.
OK
Steering pad switch illumination comes on.
HINT:
If the result is not as specified, replace the steering pad switch assembly.
- Measure the resistance according to the value(s) in the table below.
