Repair Procedures: Inspection

Measure a resistance of NTC and Heated pad.
1. NTC resistance (Brown/Black) - 10kΩ (9kΩ ~ 11kΩ), 25°C
2. Heated pad resistance (Blue, Black) - 1.73Ω (1.56Ω ~ 1.90Ω), 20°C(±1°C)
Measure a temperature.
1. The temperature of wheel surface grip must rise from -20°C to 20°C within 6 minute
2. The temperature of wheel surface grip must keep 38°C ± 4°C after 25 minute
3. Temperature measurement points (1~8)
