6
If controller now responds correctly, check that NA6 connector and 6-pin connection to controller are properly connected; replace controller if not.
7
If controller does not respond after shorting, remove harness from thermistor assembly connector and measure resistance.
8
Compare resistance to Table 1: at 50F/10C expect 18.0kΩ, at 70F/21C expect 11.7kΩ, at 90F/32C expect 7.7kΩ, at 110F/43C expect 5.2kΩ, at 130F/54C expect 2.9kΩ.
9
If resistance is out of range, replace thermistor assembly.
10
If resistance is in range, check harness-linking connector for continuity.
