Access 7 is under the cover, just under the multi control handle.
Remove the cover under the multi control handle you will see Access 7.

Kind regards,
Ram.

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.

Fact of the week
The word "robotics" was coined by Russian-born American science-fiction writer Isaac Asimov who first used the word in 1942 in his short story 'Runabout'. He characterised robots as helpful servants and as "a better, cleaner race."
