PRNDL Indicator (Park Reverse Neutral Drive Low)

The PRNDL display is a variable function electronic display located in the Instrument Panel Cluster (IPC). The PRNDL display is capable of displaying PRND321. The display electronically illuminates, or lights the back of the desired character in order to indicate the gear selection in the transmission. The IPC controls the PRNDL by use of the Class 2 messages that are received from the PCM/VCM. The vehicles with automatic transmissions have an electronic park reverse neutral drive low (PRNDL) range indicator. The system uses the signals from the neutral safety back up (NSBU) switch on the side of the transmission. Signals from this switch determine which LED is in the electronic PRNDL will light. The system is electronic. No internal adjustment is needed. Refer to Transmission/Transaxle for diagnostic information.
