M0460 – Telematics Harness Ground Wire – 2022-2024 Hino Conventional Trucks

SEOCONTENT-START

SAFETY RECALL
TELEMATICS HARNESS GROUND WIRE
RECALL NO: M0460
DATE: 2-8-2024
REFERENCE: RCB-002-24
SUBJECT VEHICLES:
2022 through 2024 model year Hino Conventional trucks that
were assembled at the Mineral Wells, West Virginia, USA
assembly plant
Note: Refer to the appropriate Vehicle Identification Number
in the warranty system to determine vehicle eligibility.
OVERVIEW:
The subject vehicle may have a ground circuit of the telematics
control unit that can become damaged because of improper
design of the telematics harness if it is not properly connected to
the battery. If a final-stage manufacturer or vehicle operator fails
to properly connect or tighten the positive or negative battery
cables, this may result in a ground loop causing unintended
currents that may cause overheating or damage to the ground
wire of the telematics harness. The following work procedure will
provide guidance for inspecting and repairing the telematics
ground circuit.
BEFORE YOU BEGIN:
• Read and understand all instructions and procedures before you begin
the work.
• Read and follow all NOTICES and WARNINGS set forth in this
publication. These alerts help to avoid damage to components, serious
personal injury, or both.
• Park the vehicle on a level and solid surface and apply the parking
brake firmly. Confirm parking brake activation.
• Confirm the engine is stopped, the starter switch is in the off (LOCK)
position, and the key is removed.
• Always wear safety glasses to prevent eye injuries.
• Place wheel chocks in front of and behind all
wheels to prevent the vehicle from moving.
PARTS:
OPTIONAL PARTS:
VEHICLE PREPARATION:
1. Park the vehicle on a level and solid surface. Confirm the engine is
stopped, the starter switch is in the off (LOCK) position, and the key is
