Monitor Scantool Data

WARNING: This page is about a different variant/trim than selected.
  1. Ignition ON/Hybrid Ready (Cluster Indicator "READY" On) Vehicle Parked.
  2. Connect GDS and select "Data Analysis" mode.
  3. Select "Current Data" mode and monitor "MCU Temperature" parameter.

    Specification:  - 22 ~ 302°F (-30 ~ 150°C)

    (Fig.2-2) Check EWP is in normal operation.

  4. If the current temperature is abnormal, check below parts.

    Check the MCU cooling system because MCU cooling system failure gives influence to HSG temperature changes.

    Check the temperature changes between MCU and GCU and HSG and LDC are similar.

    Check temperature is changing as the MCU Motor Torque is increased.

    Substitute with a known-good MCU (HPCU) and check for proper operation. If the problem is corrected, replace MCU (HPCU) and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

    After Component replacement Motor/HSG Resolver Calibration must be performed using the GDS.
