P1D93 Honda Code - Electric Powertrain Coolant Overheating
Quick Answer
The motor power inverter (MPI) module (traction/generator) and the voltage control unit (VCU) are cooled by the motor control module (traction) which operates the electric motor control module coolant pump monitoring the coolant temperature and the temperature of various components and sends a request for operation of the radiator fan to the Powertrain Control Module (PCM). Common causes include Faulty Radiator Fan, Faulty Electric Powertrain Coolant Pump, Electric Powertrain Coolant Pump harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
