1: A “change-of-state” at the “PTO-Request” circuit is required to re-invoke SEIC.

When a disabler is seen by the PCM the "PTO-Indicator" circuit changes from "ground-source" to “open-circuit". After approximately 3
seconds SEIC drops out, returning the engine speed to base idle. For vehicle-stationary operation, the automatic transmission torque
converter unlocks as engine speed proceeds below 1200 rpm. To re-initiate SEIC the operator must turn off the aftermarket PTO switch
(removing command voltage to the “PTO-Mode” circuit) and turn it back on again.
2: SEIC is automatically re-activated after approximately 3 seconds after the disabling condition is removed.

NOTES:
(1) Affects the "holding power" of the aftermarket PTO clutch.
(2) Requires battery voltage applied to “PTO” (diesel engine) or “PTO-Mode” (gas engine) circuit, engine at 1200 rpm, and torque converter locked.
(3) Vehicle road speed must be greater than zero.
(4) Consult the PTO manufacturer for more complete detail.
(5) Although actual lock-up occurs above 1050 rpm, and unlocks below 950 rpm, drawing full torque from the PTO gear is not intended below 1200 rpm engine speed.
