What is the Function and Diagnostic Process of the Neutral Safety Switch in the Park/Neutral Position and back up Lamp Switch Assembly on Chevrolet Corvette?

The external component of the park/neutral position (PNP) and back up lamp switch assembly that attaches to the transmission manual shaft operates through four internal switches which track the transmission gear range selector lever position. When the lever moves the pcm applies ignition voltage to each switch circuit so the switch states can transition between open and closed. The pcm determines the selected gear range by comparing real-time voltage combinations against stored tr switch pattern charts when high voltage means open circuit signals and low voltage signals trigger closed circuits. Diagnosing the system involves verifying the correct switch signal values in circuits a, b, c and parity where hi marks ignition voltage signals and low represents zero voltage signals. Inspect all connecters at the pcm and tr switch and other circuits between points for intermittent failures and check these circuits' wiring for possible issues. A disconnected tr switch results in the loss of ground from all tr switch circuits so the pcm detects open circuits that produce hi signals on the scan tool range information displays. To test the tr switch wiring check for an open signal voltage from the pcm through a fused jumper wire which enables the pcm testing and allows the scan tool range signal to show low when properly grounded. The process can be performed multiple times to verify correct device operation.
