Instrument Cluster with Compass and Temperature Display
The compass mini-trip computer and temperature display functions are available on the mid level instrument cluster. The compass and temperature readout is displayed in the lower left part of the instrument cluster (28) below the fuel (1) and engine coolant temperature (4) gauges. The display shows the current ambient temperature and one of eight compass readings identifying which direction the vehicle is facing. Pressing and holding the CMTC RESET button (29) allows setting of the variance zone and manual calibration of the compass. This button also is used to disable the vehicle park assist feature.
The display in the lower right part of the instrument cluster (13) below the tachometer (10) shows the vehicle odometer related functions. These functions include trip odometer, Trip A and Trip B readouts. The instrument cluster right push button (14) can be used to scroll through the different odometer functions. Refer to => [ Instrument Cluster ] Instrument Cluster.
The compass temperature display system is comprised of several different components. Those components are:
• Instrument cluster.
• Ambient temperature sensor.
• Remote compass module.
• Controller area network data bus.
• Local interface network data bus.
• Totally integrated power module.
The compass temperature display and the instrument cluster button are part of the instrument cluster assembly and cannot be serviced as separate components. If the display or button are inoperative the complete instrument cluster assembly must be replaced. Refer to => [ Instrument Cluster ] Instrument Cluster.
Instrument Cluster with Temperature Display
The temperature display function is available on the base level instrument cluster. The temperature readout for the base level cluster is displayed in the lower right part of the instrument cluster (13) along with the odometer reading. The display shows the current ambient temperature. The display also shows the vehicle odometer related functions. These functions include trip odometer, Trip A and Trip B readouts. The instrument cluster left push button can be used to scroll through the different odometer functions. Refer to => [ Instrument Cluster ] Instrument Cluster.
The compass temperature display system uses both non-switched and ignition switched sources of battery current so that some of its features remain operational at any time, while others may only operate with the ignition switch in the ON position. When the ignition switch is turned to the ON position, the display will return to the last function being displayed before the ignition was turned to the OFF position. Pressing and holding the instrument cluster push button allows setting variance zones and manual calibration of the compass.
The compass temperature display system is comprised of several different components that communicate over the controller area network and local interface network data bus circuits. If the system is inoperative a scan tool and the appropriate diagnostic information must be used to diagnose the system and related data buses.
