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).

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.

5. Check to see if there is a specific speaker that has
no sound.
Speaker(s) failed the test:
 If at least one speaker is OK, go to step 6.
 If all speakers fail to sound: – With premium audio system: Go to step 14.
– Without premium audio system: Go to step 9.
Speakers all work, but sound quality is poor in
step 1.
 If sound is poor only with XM radio, or the XM radio does not function, go to poor or no sound
with XM radio (see page 23-72).
 If the sound is poor only with AM or FM, go to poor AM or FM radio reception or interference
(see page 23-29).
 If the sound is poor only with disc. – Try several known- good disc in the navigation
unit.
– If the sound quality is normal, the original disc is faulty.
– If the sound quality is still poor, replace the navigation unit.
 If the sound is poor in all modes, go to sound quality diagnosis (see page 23-74).
6. Turn the ignition switch to LOCK (0).
7. Remove the speaker(s) with no sound (see page 23-83), and disconnect its connector.
8. Check the speaker 2P connector for a loose or poor connection.
Go to step 9.
Operation is normal.
9. Make sure the ignition switch is in LOCK (0). 10. Measure the resistance between terminals No. 1
and No. 2 of the speaker connector.
 With premium audio system: Go to step 20.
 Without premium audio system: Go to step 11. Faulty speaker(s).
11. Remove the navigation unit (see page 23-155). Disconnect navigation unit connector A (17P).
NOTE: Eject all the discs before removing the navigation unit to prevent damaging the CD player’s load
mechanism.
 Remove the PC card before removing the navigation unit.
12. Measure the resistance between the following terminals of navigation unit connector A (17P)
accordingtothetable.
