matic and Circuit Drawings in Chapter 9 -- Electrical
Diagrams).

Before testing the traction neutral switch, the switch
and its circuit wiring should be tested as an ECM input
with the Diagnostic Display (see Diagnostic Display in
the Troubleshooting section of this chapter). If the Diag-
nostic Display verifies that the traction neutral switch
and circuit wiring are functioning correctly, no further
switch testing is necessary.IftheDiagnostic Display de-
termines that the traction neutral switch and circuit wir-
ing are not functioning correctly, proceed with testing
