A system and method for controlling a current draw in a transport refrigeration system (TRS) including an electronically controlled engine having an engine control unit (ECU) are disclosed. The method includes disabling the ECU in response to the electronically controlled engine entering an operating mode in which the electronically controlled engine is not running The TRS controller determines an ambient temperature based on a temperature outside an internal space of the refrigerated transport unit. The TRS controller initializes an ECU off timer when the ambient temperature is less than or equal to an ambient temperature threshold.
