DEFINITION: The automatic transmission's gear selection (PRNDL) indicating light does not illuminate with the Ignition Switch in the Run position. However, the Voltmeter on the Instrument Cluster does indicate battery voltage. This diagnostic procedure is applicable for vehicles equipped with column shift automatic transmissions only. Brake Transmission Shift Interlock Cell 138 covers this diagnosis for vehicles equipped with a floor shift automatic transmission.
