• Check DTC for water level in coolant expansion tank for the battery cooling circuit. • Check that the water level in the coolant expansion tank is OK. • If the water level is low check for leakage in the battery coolant circuit • Check for coolant leakage in the battery pack (E83). There is a small hole in the battery coolant interface where coolant will come out if there are a leakage in the internal battery coolant circuit. • If leakage in the battery. Change defect hose according to instruction in Multi. • Perform functional test of the battery coolant circuit according to instruction in Multi • Read out the SOH value via SDP3 it should be above 52% (A new battery exchange recommendation parameter will be available later) • Change battery pack(E83) according to instruction in multi and in co understanding with the vehicle owner hence it’s a very expensive part.
