Repair procedures
1. |
Measure a resistance of NTC and Heated pad.
– |
NTC resistance (Black / Gray) :
10.0 kΩ ± 3% [25 °C (77 °F)]
8.875 - 11.27 kΩ [at 23 - 27 °C (73.4 - 80.6 °F)]
|
– |
Heated pad resistance (Black / Yellow) : 1.95 ± 0.2Ω [21 - 23°C
(69.8 - 73.4 °F)]
|
|
2. |
Measure a temperature.
– |
The temperature of wheel surface grip must rise from -20 °C (-4
°F) to 20 °C (68 °F) within 6 minute
|
– |
The temperature of wheel surface grip must keep 38 ± 4 °C (100.4
± 39.2 °F) after 25 minute
|
– |
At that time switch on, all measure point (1 - 8)

|
|
3. |
Check for continuity between the terminals in each heated steering switch.
