   • A pending DTC is a DTC that is stored in the rear motor generator control ECU during the 1st trip when 2 trip detection logic is used.
   • Freeze frame data is stored for each of the latest result DTCs, pending DTCs and confirmed DTCs.

1. If a DTC is present, select it in order to display its freeze frame data.
2. Read the freeze frame data recorded when the DTC was stored.

HINT: 

The rear motor generator control ECU maintains communication with other ECUs, such as the hybrid vehicle control ECU, ECM, skid control ECU assembly and motor generator control ECU. Therefore, if the rear motor generator control ECU outputs a DTC, it is necessary to check for and make a note of any DTCs stored for other systems.

1. If DTCs are present, check the relevant systems.

   HINT: 

   If DTCs for the CAN communication system are present in addition to other DTCs, first troubleshoot and repair in the CAN communication system malfunctions.

1. Connect the Techstream to the DLC3.
