WARNING:
To prevent the risk of high-voltage shock, always follow
precisely all warnings and service instructions, including instructions
to depower the system. The high-voltage system utilizes approximately
450 volts DC, provided through high-voltage cables to its components and
modules. The high-voltage cables and wiring are identified by orange
harness tape or orange wire covering. All high-voltage components are
marked with high-voltage warning labels with a high-voltage symbol.
Failure to follow these instructions may result in serious personal
injury or death.

PINPOINT TEST H : P0CDF:00, P0CE2:00, P0CE3:00|
Refer to Wiring Diagrams Cell 21 for schematic and connector information. Normal Operation and Fault Conditions The electric powertrain cooling system incorporates a high voltage battery coolant diverter valve. This valve opens/closes to bypass or allow the coolant flow through the high voltage battery coolant chiller. The high voltage battery chiller cools the coolant using the HVAC system that provides additional cooling to the high voltage battery when needed. The coolant valve is controlled by the BCMC via internal relay. The BCMC monitors the coolant valve for electrical faults and sets an appropriate DTC. The SOBDMC also known as the Inverter System Controller (ISC) sends a message over the HS-CAN to request the BCMC to open or close the valve. The BCMC and SOBDMC set DTC P0CDF:00, P0CD2:00, and/or P0CE3:00. DTC Fault Trigger Conditions

Normal Operation and Fault Conditions When the ignition is turned on, the BECM makes various vehicle checks. If these checks are normal, the BECM sends a signal to the contactors to close, which will supply high-voltage power to the vehicle. During the contactor close sequence the main negative contactor closes first then the pre-charge contactor to limit the amount of inrush current flow prior to closure of the positive main contactor, which supplies high-voltage power to the vehicle. The BECM utilizes a counter to prevent greater than 15 precharge events within a calibrated period of time. The counter will increment for every successful pre-charge and decrement within a calibrated parameter and period of time.

PINPOINT TEST AK : HIGH VOLTAGE BATTERY PACK CELL BALANCING FAULTS|
Normal Operation and Fault Conditions The high voltage battery pack is consisted of multiple series-connected cells. To preserve battery life and insure the battery pack good performance, it is essential to minimize the deviations between individual cell state-of-charge (SOC). Cell balancing circuit, located inside BECM, is used to achieve the objective by closing the electric circuit to discharge the cells with high SOC. Cell Balancing occurs when the high voltage battery state-of-charge (SOC) is equal or greater than 15% and the ignition has been turned off for greater than 24 hours. When cell balancing circuit is stuck open or closed, the corresponding cells SOCs are higher or lower than the other cell SOCs, and the wrench indicator will illuminate. After BECM replacement, the cell balancing circuit stuck open or closed DTC might be returned because of the unbalanced cell SOCs, and cell re-balancing is necessary to resolve the fault symptom. The stop safely hazard (red triangle) warning indicator and MIL illuminates. For DTC's P0B24:00 electric motor propulsion will be limited reducing vehicle power. DTC Fault Trigger Conditions
