DTC P1600: IMA System Malfunction: General Description

This DTC is used to determine if a malfunction is on the engine side or the IMA side when checking with the HDS. When a device on the IMA side malfunctions, the motor control module (MCM) signals the engine control module (ECM) to turn on the MIL. If the ECM receives a signal from the MCM to turn on the MIL, the MIL is turned on and a DTC is stored.
