Transmission Neutral Start Interlock
OEM
Description:
The Transmission Neutral Start Interlock allows the
engine ECM to monitor the J1929 ETC #7 message from
the transmission coltroller to either enable of disable the
engine from cranking. The Engine Running Output must
be programmed to a low side driver (J1/P1: 29, 30, or 31)
and the Powertrain Datalink must be programmed to
J1939 for this feature to function.
Programming the Neutral Start Interlock parameter to
Enabled when the ETC #7 message is not present or a
failure of the J1939 datalink, will result in the engine not
starting.
Available:
EPA’07 and newer C7, C9, C13 and C15 engines.
Range:
Range Cat Default
Enabled

Disabled
Advantages:
Allows integration of the truck controller and the engine
controller to assure proper starting procedure.
Recommendations:
✔ This parameter should be enabled when using an
automatic transmission.
