Electronic Shift Indicator (VF)

The electronic shift indicator (PRNDL) is a class 2 serial data message to the instrument cluster from the VCM. The Vacuum Florescent (VF) display utilizes the fixed gear position labels P, R, N, D, 3, 2,1 surrounded by a moveable square flag in order to indicate the selected gear position. Since the system is entirely electronic, there is not internal adjustment. The PRNDL display will operate as follows:
^ The VF PRNDL display will indicate the park position if the park position is indicated by both a class 2 serial data message and the column park switch is closed (low input).
^ The VF PRNDL display will indicate a gear position if a class 2 serial data message from the VCM is received indicating a gear position.
^ If the instrument cluster has not received a class 2 serial data message within 5 seconds of entering the UNLOCK or the RUN position, the gear position flag will be blank in order to show no selected gear position.
