connector pulled out of the control unit.
Are there disconnection, breakage and short circuit in the engine heater
connections (the engine terminals and control unit)?
Is the engine heater normal to meet the following requirements?
Insulation resistance: One (1) M or more at 500 VDC
Dielectric strength: 1000 V for one (1) minute
Leakage current: 0.3 mA or less
Resistance (in cold condition): 58.0 to 62.9
Dielectric strength: 1000 V for one (1) minute
Leakage current: 0.3 mA or less
