A lot of can commutation codes come from bad battery or battery needing water. I would start with checking the water on the battery. 700 codes are from access 7. If you have another truck, you can try swapping the access 7. If the software is not the same, you will need to update the software.

good Morning, everyone.

it says if: event code 751 occurs with 748, 749, or 750 codes.
then replaced access 7.

also, event code 755 is present access 2 not compatible with access 7 software.
must record software part numbers and contact crown for software updates.

please any advice on this? want to know should we replace access 7 or just do the software update? we will appreciate any advice.
