Eaton Fuller Hybrid Transmission ePTO Test Overview

The ePTO feature allows the diesel engine to remain off for extended periods of time during PTO usage. The DC/DC Converter is energized only in ePTO mode so it can charge the 12-volt battery system. The Hybrid Control Module (HCM) operates the Motor/Generator to power the transmission mounted PTO. If the high-voltage batteries get low, the HCM starts the engine with the Motor/Generator or the standard 12-volt system.
Select ePTO mode by pressing the Mode button on the Push Button Shift Control. Some applications use a Chassis or Body Controller to control the PTO and send information to the HCM. Other applications use the HCM to control and confirm engagement of the PTO. The Body Controlled option is referred to as the J1939 option and the HCM controlled is referred to as the Analog option.
Note: To determine which module is controlling the PTO, connect ServiceRanger and select the “Roadranger Configurations” screen. Under the Hybrid Control Module option is a listing for PTO Feedback, which is either Analog Controlled (HCM), or J1939 Controlled (Body Controller).
Note: This symptom-based test should only be performed as directed by a diagnostic procedure and you have no Active fault codes.

1. Operate the Hydraulic controls until the diesel engine turns on.
2. Connect ServiceRanger and select the Data Monitor option.
3. View the high-voltage battery list and view the PID 133 “Battery State Of Charge (SOC)”:
   • If diesel engine cycles on for some time then shuts back down, test is complete.
     Go to Step 16.
   • If diesel engine never cycles on and PID 133 “Battery SOC” is less than 23%, concern with engine. The hybrid system will attempt to start the engine when the SOC goes below 23%. Contact the OEM for repair procedures.
   • If diesel engine never cycles on and PID 133 “Battery SOC” is greater than 23%, battery SOC must be below 23% before the hybrid system will request the engine to start. Continue to operate the hydraulic controls until the engine comes on.
   • If Diesel engine cycles on and never shuts down, and PID 133 “Battery SOC” is less than 68%, go to Step 5.
   • If diesel engine cycles on and never shuts down, and PID 133 “Battery SOC” is greater than 68%, go to Step 5.

1. Connect ServiceRanger to the 9-Way Diagnostic Connector.
2. View the Data Monitor parameter PID 152 “Request Engine Run”:
   • If PID 152 “Request Engine Run” reads 0 (No Request) and PID 133 “Battery SOC” is less than 68%, the current power usage is enough to require the engine to remain on so the system can deliver the power demands. If the power demands are reduced the engine should shut down because the SOC will go over 68%.
