Repair Procedures: Removal
WARNING:
- Be sure to read and follow the "GENERAL SAFETY INFORMATION & CAUTION " before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries.
- Be sure to shut off the high voltage circuit according to the "HIGH VOLTAGE SHUTOFF PROCEDURE " before doing any work related with the high voltage system to avoid serious electrical injuries.
NOTE:
The MCU is integrated into the HPCU that can't be disassembled. So refer to "HPCU
" for the removal or installation procedure of the MCU.
- Shut off the high voltage circuit.
(Refer to Hybrid Motor System - "HIGH VOLTAGE SHUT-OFF PROCEDURE ")
- Drain the coolant of hybrid motor cooling system.
(Refer to Hybrid Motor Cooling System - "COOLANT ")
- Remove the air duct and the air cleaner assembly.
(Refer to Engine Mechanical System - "AIR CLEANER ")
- Remove the reservoir by loosening the bolts (B) after separating the hoses (A).
