2024 Prologue Model Series: New Body Repair Information
APPLIES TO
2024 Prologue Model Series

• This publication contains a summary of new body and vehicle technologies that may affect collision and other body repairs. Always refer to the service information and body repair manual (BRM) for complete repair information. A subscription may be purchased at techinfo.honda.com.
• The Prologue was co-developed in partnership with General Motors (GM). The Prologue’s service and body repair information reference GM information and may have the GM logo and likeness of GM’s format.

POST-COLLISION VEHICLE STORAGE

A damaged Prologue can be stored in either an Open Perimeter Isolation or Barrier Isolation.
Open Perimeter Isolation
Vehicle is stored in an outdoor area separated from all combustibles and structures by a minimum distance of 50 feet (15.2 m) from all sides.

Barrier Isolation

• Vehicle is stored in an outdoor area separated from all combustibles and structures with a barrier constructed of earth, steel, concrete, or solid masonry designed to contain a fire and/or prevent the fire from extending to adjacent vehicles.
• The barriers should be of sufficient height to direct any flame or heat away from adjacent vehicles.
• If the barrier is only on three of the four sides of the vehicle, the open side would need to maintain the separation distance referenced above.
• It is not recommended to fully enclose the vehicle in a structure due to the risk of post-incident fire extending to the structure, and the possibility of trapped explosive or harmful gases. Therefore, a roof is not recommended for barrier isolation.

HIGH-VOLTAGE POWER CUT-OFF

The supplemental inflatable restraint sensing and diagnostic module determines the severity of a collision with the assistance of impact sensors located at strategic points on the vehicle. The battery energy control module will open the high-voltage contactor  relays, placing the vehicle in a high-voltage lockout state and disabling the vehicle whenever a crash event of sufficient intensity has been detected.
In addition to the opening of the high-voltage contactor relays, a single-use pyro-fuse will be activated whenever the supplemental inflatable restraint system is deployed. An activated pyro-fuse will inhibit high-voltage current flow out of the battery pack to the under-hood components. Once activated, it cannot be reset and the high-voltage battery assembly must be replaced.

HIGH-VOLTAGE DISABLING

Always perform the high-voltage disabling procedure prior to removing any high-voltage components and connections.
Refer to the High-Voltage Disabling procedure in SIS for step-step-step instructions.
The procedure will cover:

• How to disable high-voltage.

• How to test for the presence of high-voltage.

• Identifying conditions under which high-voltage is always present and personal protection equipment (PPE) and proper procedures must be followed.

• The use of digital multi-meters (DMM) to disable high-voltage.

• The disable procedure only de-energizes the high-voltage circuits and components outside of the high-voltage battery.
  Dangerous voltage levels always exist within the high-voltage battery assembly.

• Refer to the Prologue Emergency Response Guide for additional information on safe practices.
  One you have safely disabled the high-voltage system, always use a lock out to prevent reconnection of the system.

VEHICLE LIFTING

The lifting points are shown in blue. Never lift the vehicle from any locations on the high-voltage battery.

Make sure to remove the Rocker Panel Molding Jacking Opening Front Cover before positioning the lift onto the vehicle.

Due to the weight of the Prologue, a 10,000-pound lift with 3-stage arms and a drive-through clearance of a minimum 95inches is required to safely lift the Prologue. Contact the Honda Tool and Equipment Program at 1-888-424-6857 for recommendations on lifts.

VEHICLE TOWING AND TRANSPORTATION

The preferred method for emergency towing is to use a flat-bed tow truck or tow dollies to transport a disabled vehicle. If tow dollies must be used, be sure to suspend the rear wheels or both front and rear wheels. DO NOT use cable-type lift equipment.

NOTE: If there is a 12-volt power failure, the vehicle cannot be shifted into neutral; Use available tow dollies.
Towing Types

Refer to the Prologue Emergency Response Guide for additional information on towing information and transportation.

BODY CONSTRUCTION & HIGH-STRENGTH STEEL CONTENT

• High-strength steel (HSS) is defined as any steel with a tensile strength of 340–440 MPa.
• Advanced-high-strength steel (AHSS) is defined as any steel with a tensile strength of 590–780 MPa.
• Ultra-high-strength steel (UHSS) is defined as any steel with a tensile strength of 980 MPa or higher.
• Steel repair and welding procedures vary depending on the tensile strength of the parts involved.
  NOTE: Some body parts are constructed from multiple layers of different tensile strength steels.
  Always refer to the body construction section of the BRM for specific steel tensile strength information.
  HSS and UHSS for the Prologue are identified below:

LASER-BRAZED ROOF

Laser-brazed roof panels require a combination of welding, use of adhesives and mechanical fasteners for replacement.
Refer to the Roof Outer Panel Replacement procedure for more details.

PAINT BOOTH CONDITIONS

• Do not use the paint booth heating system for curing applied structural adhesives. Use only infrared heaters.
• Maximum paint booth baking temperatures must not exceed 140 °F (60 °C) and 30 minutes of bake time.
• The high-voltage battery temperature must not exceed 105˚F (40.5˚C).

SHOP SAFETY

Wheel Dollies
When a vehicle has been made immobile, either through the collision repair process or a collision, avoid pushing or rolling the vehicle on its drive wheels. The wheels rotating motion may charge the high-voltage inverters and cause an electric shock to yourself and other assisting personnel if any of the high-voltage components and electrical harness is exposed. Always use wheel dollies at each wheel to move the vehicle around the repair shop.
Danger Signs
When working on high-voltage components, always place danger signs inside or around the high-voltage vehicle being repaired to inform others.

Buffer Zones
Designate a buffer zone around the vehicle and place cones around the perimeter. This will keep unauthorized personnel from entering the work area. For additional safety, cone bars with a danger sign should be used.

When removing the high-voltage battery, designate an area of the shop where it can be safely stored during repairs. A buffer zone should also be created, and cones placed for safety.

Welding Blankets
Make sure to use welding blankets when welding, cutting, and grinding around the high-voltage battery and components.

SCAN TOOLS

The Prologue will use the same vehicle communication interface tool, the MDI-2 and the Techline Connect software that is used by GM. If you already have both the MDI-2 and access to Techline Connect, they can be used for the Prologue. Do not use the DST-i or the i-HDS for this model.

SERVICE & BODY REPAIR MANUALS

The service and body repairs manuals for the Prologue will be similar to GM’s format and is integrated as part of the service manual.

DRIVING SUPPORT SYSTEMS

The Prologue features the following driving support systems:

System)
Rear Parking Sensor System| Lane Change Collision Mitigation
Low Speed Braking Function| Rear Pedestrian Alert

Refer to the information in Driver Assistance Systems Configuration Reference found on SIS for more information about each system, when to perform a learn; and how to do it.
NOTE: Some components listed may not apply to the Prologue.

There are no special paint requirements except for the front and rear parking sensors.

• Do not refinish previously painted sensors. Excess paint build-up will cause the sensor to be inoperative.
• Pay attention not to scratch the sensor. The sensor already comes prepared to be painted.
• Do not sand or prep the sensor head with a Scotch-Brite pad or equivalent. The sensor does not need to be sanded to be painted. Use only approved pre-clean solvent from your paint manufacturer.
• Apply paint, paint thickness shall not exceed 4.4 mils of paint to the head of the sensor using care to ensure the sides maintain the same paint film thickness as the top.

Refer to the specific parking sensor (referred to as Parking Assist Object Sensor) replacement procedure for more information.

COLLISION REPAIR CONSUMABLES

Structural Bonding Rivets and Adhesives
For replacement procedures on some structural components, the use of structural rivets and adhesives will be required to bond multiple structural components together. Procedures will generally list the required consumables before the removal procedure. Sourcing the required rivets will require collision centers to purchase the rivets directly from an authorized General Motors dealership. The chart below should be used when ordering these rivets.
