■ Check Resistance in BMS ECU
- IG KEY OFF.
- Disconnect Aux. battery (-) cable.
- Wait for 5 minutes after turning Main Switch OFF.
- Discommend BMS ECU connector.
- Check resistance of BMS ECU H-CAN LOW and H-CAN HIGH.
Specification: Approx. 120 Ω
WARNING: * Warning & Notice
Hybrid Battery system uses around 270V voltage.
It may cause death or damage due to electrical shock, if you Do Not follow below Instructions.- Follows instructions of workshop handbook.
- Wear and use insulated gloves and tools.
- IG "OFF", Disconnect ground cable of auxiliary battery and "OFF" the safety connector of the high voltage battery.
- Check high voltage terminal on Power Relay Assembly is lower than 30V.
- Be careful that it should not be short between terminals when measuring battery cell voltage. You may be injured due to spark, parts damage or electrical shock.
- Metallic material cause high voltage short that may cause damage of life or vehicle. Therefore, get rid of all the metallic material before working. (Metallic Material: Watch, Ring, any metallic products etc.).
- After disconnect W/H goes to BMS ECU from High voltage battery, be careful not to happen short between exposed terminal and terminal on high voltage connector.
- Is the measured value within specification?
YES
- Substitute with a known-good BMS ECU sensor and check for proper operation. If the problem is corrected, replace BMS ECU and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- This is a fault of BMS ECU itself or a intermittent history DTC which is not erased. Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
