e. Transmission Neutral Start Feature
The transmission neutral start feature is a safety feature
designed to prevent the engine from starting with the
transmission in FORWARD [F] or REVERSE [R].
Shifting into NEUTRAL [N] activates the neutral relay (in
the relay and fuse panel). When the travel select lever is
in NEUTRAL [N], electrical power flows to the starter re-
lay, allowing the starter to engage and start the engine.
Test the transmission neutral start circuit as follows:
• The starter MUST NOT operate with the travel
select lever in FORWARD or REVERSE.
• The starter MUST NOT operate when the park
lock is OFF (disengaged).
MM4760
• The starter MUST operate with the travel select
lever in NEUTRAL.
If the starter fails to turn the engine with the travel select
lever in NEUTRAL [N] and the ignition switch (11) is in the
START position (12), refer to Section 10.7.12, Engine
Start Circuit and Troubleshooting . The neutral position
contacts in the shift switch are non-repairable. Replace
the switch if defective.
