Assessment of battery management system

Topical note

Notes on battery

AH54.10-P-0001-01A

Engine

780.703 in model 910

The diagnostic system must have been connected for this purpose.

Check the battery management system control unit

1

Establish communication with battery management system control unit.

2

In the battery management system control unit, select the menu item "Fault codes and events" and read out the fault memory.

Possible existing fault codes:
(P0AA700)  The ohmmeter for insulation resistance in the high-voltage battery module has an electrical fault.
(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.
(P0E7400)  There is a battery-internal insulation fault in the high-voltage battery module.
(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.

3

Evaluating fault codes.

If the listed fault code (P0AA700) is currently present,

perform the insulation resistance measurement in the battery management system (beneath actuations).


If the measurement result is OK, the fault code (P0AA700) can be ignored.
If the measurement result is not OK, secure transportation of the high-voltage battery module is no longer permissible.

If the listed fault code is currently (P0AA700) or (P0A1F00) or (P0A7E00) or (P142900),

there is an internal fault, and thus safe transportation of the high-voltage battery module is no longer permissible.

If the listed fault code (P0E7400) is currently present or has been saved,

there is an insulation fault, and thus safe transportation of the high-voltage battery module is no longer permissible.

If the listed fault code is currently (P0AA100) or (P0AA400),

safe transportation of the high-voltage battery module is permissible with due regard to all other assessment criteria, provided that the high-voltage plugs are fitted with voltage-proof covers and these are also fixed in place with fabric tape.

If both listed fault codes are currently (P0AA100) and (P0AA400),

safe transport of the high-voltage battery module is no longer permissible.

If, due to the fault code, safe transport of the high-voltage battery module is no longer permissible,

contact the relevant MPC/the general representative immediately.
