Engine RPM Indicator

The engine RPM indicators are a series of LEDs that are set to illuminate and indicate to the driver when the engine attains a certain engine RPM. The indicators are factory preset to illuminate at certain engine RPM ranges. The total engine RPM range available to be set is 0 - 8500 RPM and there are only three possible RPM settings available for the various transmission ranges. The factory RPM presets can be changed to any preferred RPM settings but are always available at the push of a button. Pushing the reset button reverts the RPM indicator to the factory presets. The factory presets are the default settings for the engine RPM indicator. The engine RPM indicator uses the engine speed signal circuit from the PCM to determine when the engine has attained the preset RPM.

The engine RPM indicator performs a self test when the ignition is turned ON and the engine RPM indicator switch is turned ON. Refer to Supercharger Description and Operation or to Boost Control System Description in engine controls 2.0 L.
