Check battery management system control unit (N82/2)
1 | Establish communication with battery management system control unit (N82/2). |
2 | In battery management system control unit (N82/2), select menu item "Fault codes and events" and check fault memory for following fault codes: |
P0AA700 The ohmmeter for insulation resistance in the high-voltage battery module has an electrical fault.
If the listed fault code (P0AA700) is currently present, the insulation resistance measurement must also be performed in the battery management system (N82/2) (under Actuations). If the measurement result is OK, the fault code can be ignored.
If the measurement result is not OK, secure transportation of the high-voltage battery module is no longer permissible. In this case, the responsible MPC/general distributor should be contacted without delay.
P0A1F00 There is an internal fault in the battery control unit.
P0A7E00 The high-voltage battery module has overtemperature.
P142900 There is a battery-internal insulation warning in the high-voltage battery module.
If one of the listed fault codes (item 1 to 4) is current, there is an internal fault and safe transport of the high-voltage battery module is no longer permissible. In this case, the responsible MPC/general distributor should be contacted without delay.
P0E7400 There is a battery-internal insulation fault in the high-voltage battery module.
If the listed fault code (item 5) is current or stored, there is an insulation fault and safe transport of the high-voltage battery module is no longer permissible. In this case, the responsible MPC/general distributor should be contacted without delay.
P0AA100 The positive terminal contact of the contactor in the high-voltage battery is jammed closed.
P0AA400 The negative terminal contact of the contactor in the high-voltage battery is jammed closed.
If one of the listed fault codes (item 6 or 7) is current, safe transport of the high-voltage battery module is permissible, taking all other assessment criteria into account, provided that the high-voltage connections are equipped with voltage-proof caps tat are additionally fixed in place using fabric tape.
If both fault codes (item 6 and 7) are current, safe transport of the high-voltage battery module is no longer permissible. In this case, the responsible MPC/general distributor should be contacted without delay.
