COMPONENT DESCRIPTION
Ambient Sensor
Ambient Sensor Circuit
AMBIENT TEMPERATURE INPUT PROCESS
The A/C auto amp. equips a processing circuit for the ambient sensor input. However, when the temperature detected by the ambient sensor increases quickly, the processing circuit retards the A/C auto amp. function. It only allows the A/C auto amp. to recognize an ambient temperature increase of 0.33C (0.6F) per 100 seconds.
As an example, consider stopping for a few minutes after high-speed driving. Although the actual ambient temperature has not changed, the temperature detected by the ambient sensor increases. This is because the heat from the engine compartment can radiate to the front bumper area, the location of the ambient sensor.

DTC CONFIRMATION PROCEDURE
1.CHECK WITH SELF-DIAGNOSIS FUNCTION OF CONSULT
NOTE:
Diagnosis Procedure
1.CHECK VOLTAGE BETWEEN AMBIENT SENSOR AND GROUND
1 - Ground: Approx. 5V
2.CHECK CONTINUITY BETWEEN AMBIENT SENSOR AND A/C AUTO AMP.
2 - 37: Continuity should exist.
3.CHECK AMBIENT SENSOR
Check ambient sensor.
4.CHECK CONTINUITY BETWEEN AMBIENT SENSOR AND A/C AUTO AMP.
1 - 35: Continuity should exist.
1 - Ground: Continuity should not exist.

AMP on signal circuit
Description
When the audio system is turned on, a voltage signal is supplied from the AV
control unit to the BOSE speaker
amp. When this signal is received, the BOSE speaker amp. will turn on.
