Test Note:

All symptoms listed above are diagnosed using the same tests.

The title for the tests will be AC PRESSURE TOO HIGH
(STORED).

When Monitored and Set Condition:

199

AUTOMATIC TEMPERATURE CONTROL

AC PRESSURE TOO HIGH (STORED)

When Monitored:

With the ignition on and the IOD fuse installed. Also monitored during

the Cooldown Test.

Set Condition:

This DTC is set if the ATC reads the A/C Pressure Sensor value and it is

above 250 A/D counts.

DRIVER BLEND DOOR NOT RESPONDING (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set if the ATC does not receive feedback pulses within 5

seconds of the drive voltage being applied.

DRIVER BLEND DOOR RANGE TOO LARGE (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set when the ATC monitors the travel range during system

initialization and the measured range is greater than expected.

DRIVER BLEND DOOR TRAVEL TOO SMALL (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set when the ATC monitors the travel range during system

initialization and the measured range is less than expected.

EVAP TEMP SENSOR OPEN (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is displayed if the ATC detects an abnormally high voltage on

the evaporator temperature sensor signal.

EVAP TEMP SENSOR SHORTED (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is displayed if the ATC detects an abnormally low voltage on the

evaporator temperature sensor signal.

FRONT IR SENSOR AND CONTROL HEAD MISMATCH (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set if the correct ATC head is not paired with the correct IR

module (i.e. left hand ATC head paired with right hand IR module).

FRONT IR SENSOR CHANGE TOO LARGE (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC will set if the ATC head detects a temperature difference greater

than 50 degrees between the front IR sensors.

FRONT IR SENSOR HIGH (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set if the ATC reads the Front IR Sensor value and it is above

250 A/D counts.

FRONT IR SENSOR LOW (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set if the ATC reads the Front IR Sensor value and it is below

5 A/D counts.

FRONT IR SENSOR NOT CALIBRATED (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set if the ATC cannot read the IR sensor values or the IR

sensor values are not within a defined range of the HVAC air door motor counts.

FRONT KEYBOARD COMMUNICATION FAULT (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC will set if there is an internal fault in the ATC head.

FRONT KEYBOARD FAULT (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC will set if there is an internal fault in the ATC head.

FRONT MODE DOOR NOT RESPONDING (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set if the ATC does not receive feedback pulses within 5

seconds of the drive voltage being applied.

FRONT MODE DOOR TRAVEL TOO LARGE (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set when the ATC monitors the travel range during system

initialization and the measured range is greater than expected.

FRONT MODE DOOR TRAVEL TOO SMALL (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set when the ATC monitors the travel range during system

initialization and the measured range is less than expected.

PASS BLEND DOOR NOT RESPONDING (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set if the ATC does not receive feedback pulses within 5

seconds of the drive voltage being applied.

initialization and the measured range is greater than expected.

PASS BLEND DOOR TRAVEL TOO SMALL (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set when the ATC monitors the travel range during system

initialization and the measured range is less than expected.

PCI BUS SHORTED HIGH (STORED)

When Monitored:

With the ignition on.

Set Condition:

This DTC is set if the ATC detects a short to voltage on the PCI Bus circuit.

PCI BUS SHORTED LOW (STORED)

When Monitored:

With the ignition on.

Set Condition:

This DTC is set if the ATC detects a short to ground on the PCI Bus circuit.

REAR BLEND DOOR NOT RESPONDING (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set if the ATC does not receive feedback pulses within 5

seconds of the drive voltage being applied.

REAR BLEND DOOR RANGE TOO LARGE (STORED)

When Monitored:

With the ignition on and the IOD fuse installed.

Set Condition:

This DTC is set when the ATC monitors the travel range during system

initialization and the measured range is greater than expected.
