■ 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 C-CAN LOW and C-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.
