Instrument Cluster Gauges
The Instrument Cluster is made up of four analog gauges.
Speedometer
The speedometer has a 0-160 Miles Per Hour (MPH) primary scale with Kilometers Per Hour (km/h) on the secondary scale. The speedometer receives wheel speed data from the CAB via the CAN data bus and can be verified by comparing the speed signal viewed by the scan tool from the wheel speed sensors and the output seen on the Instrument Cluster. The Electronic Stability Program (ESP) indicator lamp located between the left and right turn signals in the speedometer face illuminates when it is activated by the Controller Antilock Brake (CAB), indicating the need to adjust driving behavior to the prevailing road conditions. Also located in the speedometers face are the trip odometer and the Flexible Service System (FSS) indicator/odometer (1). To the right and left of the speedometer face, mounted in the Instrument Cluster, are the control dials (2-3) for the FSS and the digital clock.
Tachometer
The 7000 RPM tachometer is red-lined at 6200 RPM. An engine speed signal is generated by the crankshaft position sensor and sent to the PCM. The PCM transmits the engine speed signal to the tachometer.
The tachometer also contains the digital clock and the transmission range indicator.
Coolant Temperature
The temperature gauge is displayed as C (Cold) and H (Hot). There are varying incremental designations between C and H.
Fuel Level
The fuel level gauge is displayed in increments of one-quarter marks displaying F (Full), 1/2 (one half tank) and E (Empty).
