Section 16 (Instrument Cluster): Clock: Operation
The clock gives an indication to the vehicle operator of the current time. The electronic digital clock is controlled by the instrument cluster microprocessor based upon cluster programming. The clock display is completely controlled by the instrument cluster logic circuit, and that logic will only allow this indication to be viewed when the multi-function indicator Liquid Crystal Display (LCD) is activated. However, the clock remains functional regardless of the ignition switch position.
The vehicle operator can choose to have the optional ambient temperature indicator displayed instead of the clock information, but the clock and ambient temperature indicator cannot be displayed at the same time. The clock or ambient temperature indicator display option is selected using the multi-function indicator clock switch on the instrument cluster circuit board. This switch is actuated manually by depressing the clock switch push button that extends through the lower edge of the cluster lens below the left end of the multi-function indicator. Actuating this switch momentarily will toggle the display between the clock and ambient temperature indicator modes. Actuating this switch twice within about one second will cause the display to toggle, but then automatically revert to the originally selected mode after about twenty seconds.
See the owner's manual in the vehicle glove box for more information on the features, use, operation and setting procedures for the clock. For proper testing of the instrument cluster circuitry that controls the clock functions, a diagnostic scan tool is required. Refer to BODY DIAGNOSTIC PROCEDURES .
