Standard Resistance:
for LH Side
Tester Connection | Switch Condition | Specified Condition |
|---|---|---|
7 (BLLH) - 10 (SVSG) |
Switch off |
1.72 to 2.64 kΩ |
Switch on (Blower Min.) |
||
Switch on (Blower Max.) |
Below 510 Ω |
|
6 (SW) - 1 (RV) |
Switch off |
2.72 to 4.08 kΩ |
Switch on (Heater Min.) |
||
Switch on (Heater Max.) |
0.28 to 0.42 kΩ |
Standard Resistance:
for RH Side
Tester Connection | Switch Condition | Specified Condition |
|---|---|---|
9 (BLRH) - 10 (SVSG) |
Switch off |
1.72 to 2.64 kΩ |
Switch on (Blower Min.) |
||
Switch on (Blower Max.) |
Below 51 Ω |
|
11 (SW) - 2 (RV) |
Switch off |
2.72 to 4.08 kΩ |
Switch on (Heater Min.) |
||
Switch on (Heater Max.) |
0.28 to 0.42 kΩ |
HINT:
As the dial is being turned, the resistance changes gradually.
If the result is not as specified, replace the refreshing seat switch.
(b) Apply battery voltage to the switch connector and check that the refreshing seat switch illuminates.
OK:
Measurement Condition | Specified Condition |
|---|---|
Battery positive (+) → 4 (ILL+) Battery negative (-) → 3 (ILL-) |
Illuminates |
If the result is not as specified, replace the refreshing seat switch.
(c) Apply battery voltage to the switch connector and check that the refreshing seat switch indicator illuminates.
OK:
Measurement Condition | Switch Condition | Specified Condition |
|---|---|---|
Battery positive (+) → 5 (IG) Battery negative (-) → 12 (E) |
Switch on |
Indicator illuminates |
If the result is not as specified, replace the refreshing seat switch.
