B0160

Diagnostic Chart:

CIRCUIT DESCRIPTION
The DIC applies 5 volts to the ambient air temperature sensor. The ambient air temperature is a thermister which varies in resistance as the temperature changes. As the resistance of the ambient air temperature sensor increases, the DIG senses a larger voltage drop across the sensor, indicating a lower temperature. As the resistance of the ambient air temperature sensor decreases, the driver information center senses a smaller voltage drop across the sensor, indicating a higher temperature.

CONDITIONS FOR RUNNING THE DTC
The DIC must be fully operational within a continuous voltage supply of 9.0-16.0 Volts.

CONDITIONS FOR SETTING THE DTC
The DIC detects that the temperature is greater than 140°C (284°F) for more than 2 seconds.

ACTION TAKEN WHEN THE DTC SETS
SC is displayed by the DIC in the compass/temperature mode when the condition is present.

CONDITIONS FOR CLEARING THE DTC
^ The DTC will become history when the DIC no longer detects a failure.
^ The history DTC will clear after 100 fault free ignition cycles.
^ You may clear the DTC with a scan tool.

TEST DESCRIPTION
The number(s) below refer to the step number(s) on the diagnostic table.
3. Tests for the proper operation of the circuit in the high voltage range.
