Transmission Shift Position Indicator Lamp: Description and Operation

TRANSMISSION RANGE INDICATOR (PRNDL)
The shift position indicator is located in the instrument cluster. It indicates the position of the manual valve lever by illuminating an LED located under the P R, N, D, 3, or L (or Autostick) gear symbol.

The Transmission Range Sensor (TRS) sends a signal to the Transmission Control Module (TCM) regarding the position of the manual valve lever. The TCM converts this signal into a Shift Lever Position (SLP) and sends the information to the BCM (Body Control Module) and the instrument cluster.

Refer to Instrument Panel And Gauges for repair procedures.

TRANSMISSION RANGE INDICATOR ILLUMINATION
The floor console mounted Transmission Range Indicator Lamp display utilizes electroluminescent technology as the light source. The only diagnostics that should be performed is to check for the presence of 12 volts on the mating wire harness connector. The electroluminescent lamp requires a 120 volt AC signal that is provided by a power converter included in the assembly. Because of a potential shock hazard, diagnostics testing of the electroluminescent lamp and power converter should be avoided. The module is not serviceable.
