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. The Hybrid Control Module (HCM) is mounted to the transmission and contains all of the software to control both the hybrid power electronics as well as the transmission operation. The HCM ignition power is a fused, single 12-volt feed that runs through the HCM 38-Way Vehicle Connector.

Fault Code 8 – Loss of Switched Ignition Power (HCM) Detection

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

Output Shaft speed must be greater than 0 RPM.

Conditions to Set Fault Code Active

Conditions to Set Fault Code:
• FMI 4 is set when the HCM loses ignition power during operation for 2 seconds or greater.

Fallback When Fault Code 8 is set the following conditions occur:

Amber “Check Hybrid” light illuminates.
Fault is stored in Hybrid Control Module (HCM) memory.
Red “Service” light illuminates and an “F” flashes in the gear display, if the fault occurs prior to power up.
- Fault is stored in Transmission Electronic Control Unit (TECU) memory due to lack of communication with the HCM.
If fault occurs while the vehicle is moving, the transmission remains in place and the clutch opens when the vehicle comes to an idle. The clutch closes and the vehicle will operate in 1st and reverse from stop.
If this fault occurs at power up, the vehicle 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 4
- Ignition Power Supply to HCM
- HCM

Warning: Warning indicates an immediate hazard, which could result in severe personal injury if you do not follow the indicated procedure.
Caution: Caution indicates vehicle or property damage could occur if you do not follow the indicated procedure.

Note: Note indicates additional detail that will aid in the diagnosis or repair of a component/system.

Follow the specified procedures in the indicated order to avoid personal injury:

1. If the high-voltage cones are around the vehicle and the lockout is installed on the PEC, the only person that should be allowed to start the vehicle is the person who signed the lockout tag.
2. Before working on a vehicle or leaving the cab while the engine is running, you should place the shift lever in “N” set the parking brake, and block the wheels.
3. For safety reasons, always engage the service brakes prior to selecting gear positions from “N.”
4. Before starting a vehicle always be seated in the driver’s seat, select “N” on the shift control, and set the parking brakes.
5. In vehicles with ePTO, the engine and/or
Motor/Generator can start in ePTO mode. Never perform any maintenance or work on vehicle, while in this mode.
6. 12-Volt Battery positive (+) and negative (-) must be disconnected prior to any welding on any Hybrid equipped vehicle.

Caution: Follow the specified procedures in the indicated order to avoid equipment malfunction or damage.
Caution: Do not release the parking brake or attempt to select a gear until the air pressure is at the correct level.
Caution: To avoid damage to the transmission during towing place the shift lever in “N” and lift the drive wheels off the ground or disconnect the driveline.

High-Voltage Warnings & Cautions

Use CO2 or Dry Chemical Fire Extinguishers.
The high-voltage wiring is covered in orange insulation or convoluted tubing and marked with warning labels at the connectors.
All Eaton® Hybrid Diesel/Electric vehicles will be marked ‘Hybrid’ on the outside of the vehicle, along with the shift label on the dash.
Refer to OEM for specific location of chassis mounted hybrid components.
Do NOT cut into the orange high-voltage cables.
Do NOT cut into or open the PEC.
Do NOT cut into or open the DC/DC Converter.
Do NOT cut into or open the Inverter.

A buffer zone must be set up and high-voltage insulated rubber gloves (class 0 with leather protectors) are required prior to working on high-voltage. Failure to follow these instructions may result in severe personal injury or death.
The rubber-insulated gloves that must be worn while working on the high-voltage system are class 0 with leather protectors. The rubber gloves should be tested before EVERY use following the rubber insulation gloves testing procedure found in “Diagnostic Tools/Service Publications” on page 6. Failure to follow these instructions may result in severe personal injury or death.
Before inspecting or working on any high-voltage cables or components the “High-Voltage Service Shutdown and Power-Up Procedure” on page 4 should be followed. Failure to follow these instructions may result in severe personal injury or death.
The Lockout and Tagout devices should only be removed by the technician that placed the Lockout and Tagout devices on the vehicle. Failure to follow these instructions may result in severe personal injury or death.
High-voltage rubber insulated gloves (class 0 with leather protectors) must be worn when working on any
high-voltage cables. The “High-Voltage Service Shutdown and Power-Up Procedure” on page 4 must be followed prior to removing any high-voltage cables. Failure to follow these instructions may result in severe personal injury or death.
High-voltage cables and wiring are orange and contain a warning label at the connectors. High-voltage components are marked with a label. High-voltage rubber insulated gloves (class 0 with leather protectors) must be used when working on any of these components. Failure to follow these instructions may result in severe personal injury or death.

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=””]

Disconnect the Inverter 56-Way Connector.
3. Reconnect the Motor/Generator 2-Way Temperature Sensor Connector.
Measure resistance at the following:
- - Inverter 56-Way Connector Pin 50 to Pin 38(MY08) / 40-Way Connector Pin 37 to Pin 36, Inverter(MY09.
  - Inverter 56-Way Connector Pin 50 to ground (MY08) / 40-Way Connector Pin 37 to ground (MY09).
Note: Gently flex the Inverter 56-Way Harness near the Connector while monitoring the resistance values.
1. If resistance is 0.8K–301.7K ohms between Pin 50 and Pin 38 (37 & 37) and resistance between Pin 50 (37) and ground is 10K ohms or greater, replace the Inverter, then go to Step 3.
