Set Multimeter to Resistance 
Remove connector X6 from the PCB
Measurement:
Test 1: Measure the resistance between pins 1 and 2 on connector X6.
Test 2: Measure the resistance between pins 6 and 7 on connector X6.
Resistances vary with temperature and should conform
approximately to the table below:
Test 2: Measure the resistance between pins 6 and 7 on connector X6.
Resistances vary with temperature and should conform
approximately to the table below:
| Temperature °C | Resistance in ohms | 0-10 | 28.8k - 19.0k |
| 10-20 | 19.0k - 12.0k |
| 20-30 | 12.0k - 8.0k |
| 30-40 | 8.0k - 5.0k |
| 40-50 | 5.0k - 3.5k |
| 50-60 | 3.5k - 2.5k |
| 60-70 | 2.5k - 1.7k |
| 70-80 | 1.7k - 1.2k |
