3. Wait for 30 seconds.
4. Check for DTCs with the HDS.
Go to step 5.

connections.
5. Turn the ignition switch to LOCK (0).
6. Disconnect the fuel tank unit 5P connector and the gauge control module (tach) 36P connector.
7. Connect fuel tank unit 4P connector terminals No. 1 and No. 3 to body ground with jumper wires. 8. Check for continuity between gauge control
module (tach) 36P connector terminals No. 32 and
No. 33 and body ground individually.
Go to step 9.
Repair an open in the wire between the gauge
control module (tach) and the fuel tank unit.

Description
Outside Air Temperature Indicator Logic Update to the outside air temperature
indicator while driving
Troubleshooting
22-279
Outside Air Temperature Indicator Calibration
The outside temperature sensor is located behind the
center of the front bumper. The gauge control module
(tach) uses measurements from this sensor to display
the outside air temperature.
Because of the location of the sensor, it may be affected
by heat reflection from the road, engine and radiator
heat or hot exhaust from surrounding traffic.
These conditions can heat soak the outside air
temperature sensor and cause inaccurate readings.
Logic has been written into the gauge control module
(tach) to help prevent abnormal or fluctuating outside
air temperature indicator readings.
Initial outside air temperature indication after the
ignition switch is turned to ON (II).
 If the engine coolant temperature is 60 °C (140 °F) or higher when the ignition switch is turned to ON (II),
the outside air temperature indicated the last time the
key was turned off will be displayed regardless of the
current temperature measured by the outside air
temperature sensor.
 If the engine coolant temperature is 59 °C (139 °F) or lower when the ignition switch is turned to ON (II), the
current temperature measured by the outside air
temperature sensor will be indicated. If the temperature measured by the outside air
temperature sensor is greater than the temperature on
the outside air temperature indicator, the outside air
temperature indicator will increase by 1 °C (1.8 °F) per
minute after the vehicle speed is greater than 30 km/h
(19 mph) for more than 1 minute and 30 seconds. It will
continue to increase until the current outside air
temperature is indicated. So, the first change to the
outside air temperature indicator is 1 minute and
30 seconds after the vehicle speed is greater than
30 km/h (19 mph). If the vehicle speed drops below
30 km/h (19 mph), the indicator will not update again
until the vehicle speed is increased to 30 km/h (19 mph)
or more for more than 1 minute and 30 seconds again.
If the outside air temperature is less than the indicated
temperature, the temperature will decrease 1 °C every
2 seconds (1 °F
every 1.1 seconds) until the current
outside air temperature is indicated regardless of
vehicle speed.
If the indicator displays ‘‘ ’’ for more than 2
seconds after selecting the outside air temperature
display mode, check the outside air temperature sensor
(see page 21-68), or gauge control module self-
diagnosis (see page 22-241).

Calibration
Example:
Incorrect value = 20 °C (68 °F)
Desired correction value = 1 °C ( 2 °F)
Correct value = 21 °C (70 °F)
Desired correction value = 1 °C ( 2 °F)
Correct value = 19 °C (66 °F)

Outside Air Temperature Indicator Calibration (cont’d)
B
A
C
The outside air temperature indicator’s displayed
temperature can be recalibrated 3 °C (or 5 °F) to
meet the client’s expectations. 1. Turn the ignition switch to ON (II).
2. Select the outside air temperature display.
3. Press and hold the SEL/RESET button until the trip meter resets, then release it. Press, and continue to
hold, the switch again, and the display will scroll
through temperature settings from 3 °C to 3 °C
(or 5 °F to 5 °F) as shown.
4. When the desired correction value appears on the display, release the button, and the recalibrated
outside air temperature will be displayed.
NOTE: To recalibration temperature is not the value
the sensor sees. Therefore the temperature can
only be adjusted degrees from the sensor. NOTE: To recalibrate the display to the true
temperature, remove the outside air temperature
sensor (A), but leave it connected. Submerge the sensor
and a thermometer (B) in a container of ice water (C).
Select the calibration mode as described above, then
recalibrate the display to the true temperature.

The GA-Net bus passes audio and navigation commands throughout the navigation and audio components.
These commands include navigation touch screen and hard button signals, audio/XM selections by voice, and XM
station and music title names. Because the entire bus is daisy chained between components (see diagram), any open
or short in the GA-Net bus harness will cause any or all of these functions to become inoperative. The addition of any
audio accessory must maintain the continuity of the GA-Net bus by installing the Y cable included with the accessory
kit.
