• Visually check status of the interlock loop control switch and the VCA and VCB connectors on the battery pack(E83). If the control switch is in position 1 and all connectors are connected perform a continuity check of the interlock loop. • Continuity check of the interlock loop vehicle side: • Disconnect the VCB connectors to the battery pack battery pack(E83) VCB connector (C and B) and perform a manual continuity measurement “Beep measurement” between pin B-2 to B-3 and C-2 to C-3 on the cable connector. Check also that the interlock pins are straight and not pushed deeply into the connector . Perform continuity measurement on the loop between the battery pack(E83) VCA connector A-10 and A-12 and the interlock loop control switch. Replace any broken cables or parts see drawing 2098187 and 2147897 for cable routing. • Dismount the battery pack according to instruction in multi and place the battery on a work bench • Continuity check of the interlock loop battery side: • Measure between pin B on the negative VCB connectors and pin C on the positive VCB connector • If no connection check the interlock loop connectors on the VCB-connector housing inside the battery pack • Measure between pin C on the negative VCB connectors and pin 12 on the VCA connector • If no connection toggle the micro switch to check it’s functionality • If no connection check the connectors to the IBU • Change the IBU NOTE! Replacing the IBU is considered an electrical work and shall only be performed by certified personnel. Vehicle shall be made safe according to electrical work procedure.
