• Check and tighten the ground connections to the battery pack (E83), DCC(E84), MGU(E82), electric machine(M33), VCB central electric unit (P7) and the grounding point in the HRU/HPU(G63) • Perform a visual inspection of the VCB-connectors in the battery pack (E83), DCC(E84), MGU(E82) and electric machine(M33) • Disconnect the connector from the component and measure that there is a connection between the connector housing and the component via the cable shielding and the ground connection. • If any connector has bad shielding connection change the harness according to instruction in Multi • Measure the capacitance of the filter components in the MGU, VCB central electric unit and the DCC. Measure from + to GND and – to GND. It should be 1,4µF in the MGU, 0,68µF in the central electric unit and 28nF in the DCC. Disconnect the components from the VCB central electric unit before measurement. • If any component have incorrect capacitance, change the component according to instruction in Multi • Even if the problem is solved the battery pack might still be damaged. If the DTC is still set change battery pack (E83) according to instruction in multi and in co understanding with the vehicle owner hence it’s a very expensive part. NOTE! Performing measurements within the VCB central electric unit is considered an electrical work and shall only be performed by Scania certified personnel. Vehicle shall be made safe according to electrical work procedure.
