Current data Analysis
WARNING: This page is about a different variant/trim than selected.
- IG key "ON"/Ready, Transmission Shift Lever "P" range.
- Select "Current Data" with GDS.
- Operate the vehicle within DTC Enable conditions in General information.
- Monitor "MCU (GCU) Temperature" parameter.
Reference Data
MCU TEMPERATURE REFERENCENormal □ MCU (GCU) Temperature: -20°C~105°C Abnormal □ MCU (GCU) Temperature: -30 °C momentarily displayed.
□ MCU (GCU) Temperature: 180 °C momentarily displayed.
□ MCU (GCU) Temperature: Not changed.
□ MCU (GCU) Temperature: 214°C or 215°C - Is the displayed current data normal?
YES
- Fault is intermittent caused by Poor Contact in the inside temperature sensor's connector of GCU*.
→ Repair or replace as necessary, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Check for EWP* fault and amount of coolant.
- Substitute with a known-good GCU (HPCU)* and then check for proper operation.
→ If the problem is corrected, replace GCU (HPCU)*.
→ Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NOTE:
GCU*: "HYBRID INVERTER"
EWP*: "ELECTRIC WATER PUMP (HEV)"
GCU (HPCU)*: "HYBRID POWER CONTROL UNIT_HPCU"
EWP*: "ELECTRIC WATER PUMP (HEV)"
GCU (HPCU)*: "HYBRID POWER CONTROL UNIT_HPCU"
NOTE:
After Drive Motor is replaced or reinstalled, must perform the following.
- Perform "Motor/HSG Resolver Calibration" procedure in "HCU/LDC" system →"Vehicle S/W Management"
WARNING:
Non-compliance with the following instructions can induce death or injury caused by electric shock.
- Carefully read and follow service information instructions.
- Wear insulated gloves, safety glasses and use insulated tools for your safety.
- Turn IG key switch off and disconnect ground cable of auxiliary battery and remove the safety plug.
- Wait for more than 5 minutes so that the inverter capacitor can be naturally discharged.
- Check the high voltage terminal on the power relay assembly is lower than 30V.
