Fault code for Eaton Hybrid Drive Systems models (MY08) EH-8E306A-U, EH-8E306A-UPG, EH-8E306A-UP, EH-8E306A-CD, EH-8E306A-T, EH-6E606B-CD, (MY09) EH-8E406A-U/P, EH-8E406A-UP, EH-8E406A-UPG, EH-8E406A-CD, EH-8E406A-CDG, EH-8E406A-CDR, EH-8E406A-T, EH-6E706B-CD, EH-6E706B-P and EH-6E706B-UPG. Read below to learn how to test, clear and fix fault code errors for your Freightliner, Mack, Peterbilt, Kenworth, Volvo, International, and heavy-duty truck and equipment. The Transmission Electronic Control Unit (TECU) is connected to the shift device, which sends driver mode selection data. The only compatible shift device is the Eaton® Push Button Shift Control (PBSC) and OEM supplied shift lever (if equipped with park). The TECU checks the vehicle for the type of shift device during the first power up.

Fault Code 84 – Shift Control Device Not Configured Detection

The following preconditions must be met before the system detects the fault:

TECU ignition voltage is greater than 7 volts and less than 16 volts.
TECU System Battery Voltage Low Fault is Inactive.
TECU is being powered up for the first time and no shift device has been configured.

Note: When troubleshooting an Inactive code refer to the Product Diagnostic Mode (PDM)

Conditions to Set Fault Code Active

FMI 13 is set when the TECU powers-up the first time and fails to recognize any valid shift device connected to the vehicle within five seconds.

Fallback When Fault Code 84 is set the following conditions occur:

Red “Service” light may or may not come on depending on the failure.
Fault is stored in TECU memory.
TECU changes to “AutoShift Fallback” mode.
The engine does not crank.

Conditions to Set Fault Code Inactive

Only Inactive faults can be cleared from the Transmission Electronic Control Unit (TECU) or HCM history using ServiceRanger. The TECU automatically clears the faults from history after 200 hours and the HCM automatically clears the faults from history after the fault has been Inactive for 200 hours.

This fault code can be caused by any of the following:

FMI 13
- OEM Wiring Harness between TECU and shift control device is disconnected
- PBSC
FMI 14
- OEM Wiring Harness between TECU and shift control device is disconnected
- Shift Lever

High-Voltage Service Shutdown Procedures

1. Follow “High-Voltage Work Area” procedure.
2. Locate the red PEC Service Switch on the front of the PEC and push switch off.
3. Remove the Service Switch Cover and install the Lockout Bracket (J48506).
4. Fasten tag to the Lockout Bracket.
5. Ensure the PEC Service Switch can not move from the off position.
6. Allow the system to set for a minimum of 5 minutes to discharge high voltage.
7. Connect ServiceRanger and view the Data Monitor PID 116 called “High-Voltage Battery Potential.” Use SPN 520323 for J1939 connection “Battery Voltage RB” (Relay Box).
8. The voltage should be 30 volts or less. If the voltage is above 30 volts, do not work on the vehicle and contact Eaton® at 1-800-826-HELP (4357).
9. Turn ignition key off and proceed to repair or troubleshooting step.
Note: The voltage drops to zero when the key is off.

High-Voltage Service Power-Up Procedure

1. Install all high-voltage connectors into their locked positions.
2. If you are the person working on the vehicle, remove the Lockout Bracket and tag.
3. Reinstall the Lockout Bracket over the Service Switch.
4. Pull the Service Switch out and let vehicle set for 2 minutes.
5. Start vehicle when appropriate.[/fusion_modal][fusion_modal name=”component_location” title=”Eaton Hybrid Component and Connector Location ” size=”large” background=”#ffffff” border_color=”” show_footer=”yes” class=”” id=””]
