Yukon 4WD V8-6.5L DSL Turbo VIN S (1997)
Shift Indicator: Description and Operation
Electronic PRNDL
Vehicles with automatic transmissions have an electronic PRNDL. The system utilizes signals from the Neutral Safety Back Up (NSBU) switch on the
side of the transmission. Signals from this switch determine which LED's in the electronic PRNDL will light. Since the system is entirely electronic, there
is no adjustment.
