Engine Speed Power Take-Off Control Module Programming and Setup
Programming
The power take-off module (PTOM) requires no programming or setup. When the PTOM is replaced, all programmable parameters will be defaulted back to factory settings. Remote start, if equipped and previously enabled, will have to be re-enabled through the body control module (BCM).
Module Setup
The power take-off module requires that several parameters be setup according to customer requirements. Refer to the table below for available parameters and recommended setting. Refer to the GM Upfitter Integration website,
Note:
When programming the PTO control module be sure to verify the ECM PTO options (stationary, variable or mobile) are synchronized with the PTOM. Example, if the PTOM is set to stationary mode then the ECM must also be set to stationary mode. If the two modules are not synchronized no PTO idle up will occur. The critical parameters are listed below:
* Remote engine shutdown
* Maximum PTO engine speed
